From Wikipedia, the free encyclopedia

 

Chionactis palarostris, commonly known as the Sonoran shovelnose snake, is a species of small nonvenomous colubrid which is a native of the Sonoran Desert in North America. It is one of only two species in the genus Chionactis.[2]

Chionactis palarostris

Conservation status

Scientific classification :

Kingdom:Animalia

Phylum:Chordata

Subphylum:Vertebrata

Class:Reptilia

Order:Squamata

Suborder:Serpentes

Family:Colubridae

Subfamily:Colubrinae

Genus:Chionactis

Species:C. palarostris

Binomial name :

Chionactis palarostris
(Klauber, 1937)

- - Shovel-nosed snake :

Etymology :

 

The specific name, palarostris, is from Latin: pāla (shovel) and rōstrum (beak or snout).

 

Geographic range :

 

C. palarostris is found in the southwestern United States and northwestern Mexico. In the United States it is found only in Organ Pipe Cactus National Monument of western Pima County, Arizona. Thesubspecies occurring there is called the Organ Pipe shovelnose snake (C. p. organica). In Mexico it is found only in the state of Sonora.[3]

 

Description :

 

C. palarostris is cross-banded with black, yellow (or whitish), and red bands. Consequently, it resembles the Sonoran coral snake (Micruroides euryxanthus). The mnemonic "red on yellow kill a fellow, red on black, friend of Jack" doesn't work with this snake. However, unlike the coral snake, which has a black snout, Chionactis palarostris has a yellow snout and is not venomous. Also on a coral snake, the bands go all the way around, but C. palarostris has a solid yellow belly.[4]

 

The smooth dorsal scales are arranged in 15 rows at midbody; ventrals, 141-181; subcaudals, 34-64, divided.[4]

Maximum total length (including tail) of adults is 43 cm (17 in).

Subspecies :

 

Two subspecies are recognized, including the nominotypical subspecies.

  • Chionactis palarostris organica Klauber, 1951 - Organ Pipe shovelnose snake

  • Chionactis palarostris palarostris (Klauber, 1937) - Sonoran shovelnose snake[5]

Synonyms

  • Sonora palarostris Klauber, 1937

  • Chionactis occipitalis palarostris— H.M. Smith & Taylor, 1950

  • Chionactis palarostris— Stebbins, 1985[1]

Behavior :

 

C. palarostris is active in the evening and at night, mostly near washes.

 

Diet :

 

Snakes of the genus Chionactis prey upon insects and other arthropods such as centipedes, scorpions, and spiders. They also eat the pupae ofants, butterflies and moths, and other insects; and they have been known to eat the eggs of small species of lizards.[6]

 

Reproduction :

 

Sexually mature Chionactis mate in spring, and the female lays a clutch of up to five eggs in summer.

WESTERN SHOVEL-NOSED SNAKE   

WESTERN SHOVEL-NOSED SNAKE   

 Chionactis occipitalis

 

courtesy to :  www.reptilesofaz.org/Snakes-Subpages/h-c-occipitalis 

DESCRIPTION: A small (up to 369 mm or 15" in total length) snake with more than 20 dark brown to black bands on a cream to light yellow background. Some subspecies have secondary orange saddles between the black bands (see subspecies descriptions below). The orange saddles are separated from the black by a margin of cream to light yellow background color. The posterior black bands usually completely encircle the body but the anterior bands do not. The snout is cream or light yellow. A black mask crosses the top of the head and covers the eyes. The underside is cream. With its countersunk jaw, valves in the nasal passages, concaved belly, and relatively flat snout, this snake is well equipped for burrowing under fine sand and loose gravel. The pupils are round and the scales are smooth and shiny. The Western Shovel-nosed Snake's light snout distinguishes it from the similar looking Sonoran Coralsnake which has a black snout. The similar Sonoran Shovel-nosed Snake has fewer than 21 black body bands. 

DISTRIBUTION: This snake is found in the low deserts of western and south-central Arizona at elevations ranging from near sea level to ca. 2,500'. Populations in the eastern portion of this snake's range appear to be in decline. Populations near Tucson and Paradise Valley have been extirpated.

 

HABITAT: Lower Colorado River Sonoran Desertscrub and Mohave Desertscrub communities are home to this snake. It is usually found in or near sandy washes or dunes in desert flats or on gently sloping bajadas.

 

BEHAVIOR: This snake is a ground dweller. It is primarily crepuscular but is occasionally active into the night and on mild days. Most surface activity occurs in spring. A good burrower, this snake spends most of its time under sand or sandy soil. It hibernates under the sand or soil during the cold months of fall and winter. 

 

DIET: The Western Shovel-nosed Snake feeds on a variety of invertebrates including insects, spiders, centipedes, and scorpions. It may occasionally eat reptile eggs.

 

REPRODUCTION: Mating takes place in spring and a clutch of up to 9 eggs is laid in the summer.
 

 

SUBSPECIES FOUND IN AZ:
COLORADO DESERT SHOVEL-NOSED SNAKE Chionactis occipitalis annulata. This subspecies usually has relatively narrow black bands, more space between bands, and orange saddles that are "clean" (not flecked with black or brown). 
TUCSON SHOVEL-NOSED SNAKE Chionactis occipitalis klauberi.The orange secondary saddles are usually heavily flecked with black or purplish-black on the sides but are usually immaculate mid-dorsally.
MOHAVE SHOVEL-NOSED SNAKE Chionactis occipitalis occipitalis.Narrow secondary saddles are usually very faint or lacking. Only the tail bands and the most posterior body bands cross the belly.

Sri Lankan wolf snake

 

 

Lycodon aulicus, commonly known as the Indian wolf snake, is a species of nonvenomous snake found in South Asia and Southeast Asia. Early naturalists have suggested its resemblance to the venomous common krait as an instance of Batesian mimicry.[2]

Binomial name:

Lycodon aulicus
(Linnaeus, 1758)

Synonyms :

Coluber aulicus Linnaeus, 1758
Lycodon aulicus - F. Boie, 1827[1]

Description:

 

The colouration of this snake is variable.

 

This snake is often confused with the common krait. The presence of a loreal shield can be used to distinguish it from kraits.

The following is a description of various forms from Albert Günther's Reptiles of British India (1864).

 

 

Snout broad, much depressed, long, spatulate, with the upper lip swollen, and without canthus rostralis. Rostral shield very low, broad, slightly bent backwards on the upper surface of the snout; anterior frontals [= internasals] very small; posterior frontals [= prefrontals] longer than broad, much more so in adult specimens than in young ones; there is a lateral notch between the anterior and posterior frontals, in which the inner anterior angle of the loreal is received; the posterior frontals have an obtuse lateral angle corresponding to the suture between loreal and praeocular; occipitals elongate. Nostril small, directed upwards, between two nasals, the anterior of which is situated on the foremost part of the snout. Loreal single, large, nearly twice as long as broad. Praeocular single, in contact with the vertical [= frontal] and with the third labial; specimens in which it does not reach the vertical are very scarce. Two postoculars; supraciliary rather small. Nine upper labials, the third, fourth, and fifth of which enter the orbit. Temporals numerous, scale-like. Scales smooth, with a minute apical groove, in seventeen rows. Abdomen and tail with an angular ridge on each side. Ventrals 183-209; anal bifid, in a few specimens entire; subcaudals 57-77. Each maxillary is armed with two fangs in front, placed in a transverse line, the outer being much larger than the inner; the lateral longitudinal series of teeth commences at some distance from the fangs; they are small, from four to twelve in number, the last being considerably larger than the others; pterygoido-palatine teeth small, of equal size; mandible with two or three fangs on each side and with a series of small teeth.

 

 

 

 

Coloration variable.

  • I. Continental varieties. The posterior frontals are moderately elongate-in young specimens nearly as broad as long. Each upper labial with a brown spot. [To this category belong also specimens from the Philippine Islands.]

    • Var. a. Uniform brown above, without collar: Malayan peninsula, Bengal, Madras.

    • Var. b. Uniform brown above, with a while collar: Madras.

    • Var. c. Brown or greyish brown, With indistinct traces of a white network, and with a white collar, more distinct in young specimens than in old ones: Coast of Malabar, Pinang, Malayan peninsula, Gamboja, Philippine Islands, Timor.

    • Var. d. Ferruginous or chestnut-brown, with white, brown-edged cross bars on the back, which are sometimes bifid on the sides, the branches of one band joining a branch of the preceding and following bands. The first band forms a collar; those on the hind part of the body gradually become indistinct. This variety is very common, and similar to, but specifically distinct from, the snake figured by Russell (i. pl. 16): we have received it from Pinang, Bengal, Nepal, Kangra (Himalayas), the Dekkan, and the Anamallay Mountains.

  • II. Ceylonese varieties. The posterior frontals are much elongate, much longer than broad in every age. Upper labials while or shaded with brown.

    • Var. e. Uniform brownish grey above.

    • Var. f. Brown, with three or four broad, distant, white cross bands on the anterior half of the body; the anterior forms a collar, the others being broadest on the sides.

    • Var. g. Brown or greyish, with pure-while or reticulated while cross bands extending downwards to the belly, where they are broadest.

A south Indian specimen

The following description is from Boulenger's Fauna of British India, Reptilia and Batrachia volume (1890):

 

Snout much depressed, with swollen lips, spatulate in the adult; eye rather small. Rostral much broader than long, just visible from above: internasals much shorter than the prefrontals; frontal usually shorter than its distance from the end of the snout or than the parietals ; loreal elongate, not entering the eye; one praeocular, usually in contact with the frontal; two postoculars; temporals small, scale-like, 2+3 or 3+3; 9 upper labials, third, fourth, and fifth entering the eye; 4 or 5 lower labials in contact with the anterior chin-shields, which are longer than the posterior. Scales smooth, in 17 rows. Ventrals 183-209, obtusely angulate laterally; anal divided; subcaudals 57-77, in two rows. Coloration variable; uniform brown above, or with white transverse bands, or with white reticulation; upper lip uniform white, or with brown spots; lower parts uniform white.

 

Total length 51 cm (20 inches); tail 11 cm (4¼ inches).[3]

Habitat: India and Ceylon, Himalayas, Burma, Siam, Malay Peninsula, Java, Philippines, Timor. A common snake in India.

Scalation :

 

The rostral touches six shields. The frontal touches the parietals, supraoculars, prefrontals and preoculars. The supraoculars are small. The parietals are one and a half times the size of the frontal. The preoculars are entire, while the postoculars and temporals are divided into two shields. There are nine supralabials, with the 3rd, 4th, and 5th touching the eye. The ventrals are 170 to 224 in number. The anal shield is divided. The subcaudals are 56 to 80 and are divided.

 

 

 

Distribution

 

Lycodon aulicus is found in Pakistan, Sri Lanka, India (north to Himalayas and Assam;Maharashtra), Bangladesh, Nepal, Myanmar (= Burma), Thailand (incl. Phuket), W Malaysia,Indonesia (southward as far as Timor), Philippines, Seychelles, The Maldives (accidental introduction), Mascarenes, Mauritius (introduced), S China (from Fujian and Guangdong westward to Yunnan, incl. Hong Kong). It is one of the most common snakes of India and Ceylon, but becomes scarcer on the coasts of the southeastern parts of India. It occurs on only a few of the islands in the Philippines.

Another south Indian specimen (melanistic) from Sholayar reserve forests, Kerala.

Behaviour :

 

The Indian wolf snake is nocturnal and is inactive in the day. Günther (1864) writes that it is of fierce habits and defends itself vigorously, however it is nonvenomous. It is known to defend itself when barred of escape, and can cause severe lacerations with its fine sharp "fangs".

 

Diet:

 

Lycodon aulicus feeds on lizards and frogs. According to Günther (1864) it is one of the most formidable enemies of the skinks, which form almost its sole food, the "fangs" in the front of its jaws being admirably adapted for piercing and making good its hold on the hard smooth scales with which those lizards are coated.

 

Reproduction :

 

Females may be larger than males. They breed prior to the monsoons and lay 4-11 eggs.

The eggs hatch in September or October, and the hatchlings are 14-19 cm (5½-7⅜ inches) long.[4]

Western hognose snake 

From Wikipedia, the free encyclopedia

 

The western hognose snake (Heterodon nasicus) is a species of non-venomous colubrid endemic to North America.

Western hognose snake

Etymology

Scientific classification:

Kingdom:Animalia

Phylum:Chordata

Subphylum:Vertebrata

Class:Reptilia

Order:Squamata

Suborder:Serpentes

Family:Colubridae

Subfamily:Xenodontinae

Genus:Heterodon

Species:H. nasicus

Binomial name :

Heterodon nasicus
Baird & Girard, 1852

Western hognose snake

Conservation status

The subspecific name, gloydi, is in honor of American herpetologist Howard K. Gloyd (1902-1978).[2] The subspecific (or specific) name,kennerlyi, is in honor of American naturalist Caleb Burwell Rowan Kennerly (1829-1861).[2]

 

Common names for this species include western, texas or prairie hognose snake, blow snake, bluffer, faux viper, spoonbill snake, spreadhead snake, and Texas rooter.

 

Taxonomy:

 

Some authors elevate H. n. kennerlyi, also known as the Mexican hognose snake, to species level. Those same authors have subsumedH. n. gloydi into H. nasicus so that there are only 2 species (H. nasicus and H. kennerlyi) and no subspecies.[citation needed]

 

Distribution and habitat :

 

The western hognose snake occurs from southern Canada throughout the United States to northern Mexico. It frequents areas with sandy or gravelly soils, including prairies, river floodplains, scrub and grasslands, semi-deserts and some semiagricultural areas.[1] It has been found at elevations of up to 2500 m.[3]

 

Description :

 

Western hognose snakes are relatively small, stout-bodied snakes. Their color and pattern is highly variable between subspecies, although most specimens appear much likerattlesnakes to the untrained eye, which appears to be defensive mimicry. Males are considerably smaller than females, with adult lengths rarely exceeding 15–20 inches (38–51 cm). These snakes get their common name from the modified rostral (nose) scale that is formed in an upturned manner, providing a very "hog-like" look. Additionally, this adaptation makes these snakes adept burrowers.[4]

The species is non-venomous, but possesses a potentially irritating saliva that may cause symptoms like negligible to localized slight swelling and itching. The extremely rare bite from this rear-fanged snake is not regarded as of medical importance to humans.[3]

Ecology :

 

Behavior:

 

The western hognose snake is primarily diurnal. It is typically a docile snake (though known to be highly aggressive in some individuals). If threatened (or perceiving a threat), it may flatten its neck (much like a cobra), hiss, and make mock strikes if harassed. Occasionally, if stressed enough, it even plays dead. Although it is more common that they will flatten their heads out, some individuals may puff up, filling their throats with air. This is more common with adolescent males.[citation needed]

 

Diet :

 

In the wild, they feed predominately on amphibians, such as large and medium-sized tree frogs, as well as small or medium-sized toads and small lizards. There have been accounts of H. nasicus eating the occasional rodent in the wild as well. Not being a true constrictor, Heterodon bites and chews, driving the rear fangs into the prey as a way of introducing the saliva to help break down the toxins from toads. There have been many cases of hognose snakes in captivity that will not eat for about two to three-and-a-half months, from the months January to mid March. This is because hognose snakes' instinct is to brumate underground during the winter months.[citation needed]

 

Reproduction :

 

 

Western hognose snakes have been observed in copulation as early as February and March. They are oviparous, with females laying 4-23 elongate, thin-shelled eggs in June–August. The eggs take approximately 60 days to hatch. Hatchlings are 13–23 cm (5–9 inches) in total length and reach sexual maturity after approximately two years (this is predominantly based on size, not so much age).[5]

Subspecies

Conservation :

 

Although some local declines have been reported, the species is widespread, has a large overall population size (>100,000), and is effectively protected by a variety of conservation programs. It is therefore currently classified as Least Concern by the IUCN. The eastern hognose snake (Heterodon platirhinos) is classified as a threatened species in some regions of its range and is therefore protected under those state's laws.[1]

Western Hognose Snake Care Sheet

 

courtesy to :  www.reptilesmagazine.com/Western-Hognose-Snake-Care-Sheet/

BY JEFF CLAYTON

 

 

This is a “pink pastel” western hognose snake.

Western hognose snakes come in a variety of colors. This is a “peach” specimen.
 

It has a stout build, is covered in keeled scales, and possesses a sharply upturned snout that is used for digging and burrowing in loose sandy soils and to hunt for prey. Dorsally, the Western hognose has a ground color of tan, brown, gray or olive, with darker, somewhat square blotches or bars, or rows of parallel spots that run longitudinally along the body. Ventrally, the Western hognose has glossy black scales, often interspersed with white, yellow or orange.

 

The Western hognose is probably best known for its wide array of harmless defensive ploys, sometimes accompanied by a loud hiss that is achieved by the snake forcing air through its unique skull and rostral bone structure. Added to this is the Western hognose’s ability to compress, or flatten, its body when threatened (this might be an attempt on the snake’s part to appear larger and more dangerous to would-be predators). Often while in hissing mode, a Western hognose will also flatten out the ribs along its neck, or “hood” like a cobra. This bluff is most impressive with mature animals; in younger snakes it’s quite amusing.

 

An alarmed Western hognose will also strike, often repeatedly with a closed mouth in a series of either forward or sideways movements. When a Western hognose does strike, it hits the predator with its heavily keeled snout, but does not bite.

 

Finally, on occasion the Western hognose—most often younger animals—will play dead when it has exhausted its other defenses to ward off danger. The snake rolls over onto its back, with mouth agape and lolling tongue. When flipped upright by hand, it will resume its death feign by rolling back onto its back, which can be quite amusing to witness. This death act is also sometimes accompanied with the Western hognose squirting a foul-smelling musk from anal glands located on either side of the cloaca (not as amusing to witness).

 

With increasing varieties of color phases, patterns and genetic mutations, its ease in care, and its uniqueness, the Western hognose is a great choice for new and seasoned reptile enthusiasts. I have worked with the Western hognose for many years, and it is my absolute favorite snake to keep and work with.

 

Western Hognose Snake Availability

 

Due to the growing number of Western hognose breeders around the world, there is now a greater availability of animals, along with increasing choices of pattern and genetic mutations and great color phases.

 

Western Hognose Snake Size

 

Female Western hognoses can grow to a maximum size just short of 3 feet, with a weight that normally does not exceed 800 grams. Males are somewhat smaller, averaging between 14 to 24 inches.

 

Western Hognose Snake Life Span

 

Western hognoses may live up to 18 years in captivity.

 

Western Hognose Snake Caging :

 

A Western hognose does require a secure cage, even though it is not as adept at escape as other snakes. A plastic, 5-gallon terrarium with a secure lid is ideal for a hatchling. These are inexpensive and widely available at most pet stores that sell reptile supplies. An adult Western hognose can be kept in a 20-gallon aquarium set up. The Western hognose is a ground-dwelling species, so opt for an enclosure with a greater amount of floor space; height is not as important.

 

If housing several specimens, it can be more economical to use large, clear, plastic shoe or sweater boxes, the size of which depends on the size of the animals. I normally use three different sizes: 5-liter boxes for established hatchlings, 30-quart boxes for adult males and 40-quart boxes for adult females. Shoe and sweater boxes should have ample ventilation, especially in more humid regions, which can be achieved by drilling holes into them.

 

I recommend keeping the cage furniture simple.  A sturdy water bowl and a hide box or two will suffice.

 

Western Hognose Snake Substrate

 

For hatchling Western hognoses, the best substrate is newspaper. While it is not the most aesthetically pleasing, it is inexpensive, inhibits the growth of bacteria and eliminates the threat of a hatchling ingesting substrate that could cause an abdominal impaction. 

 

Shredded aspen bedding is the most popular substrate for adult Western hognoses. It is easy to clean, allows the snakes to burrow, and, unlike cedar and pine, it is not hazardous to a snake’s respiratory system. Also popular, and generally safe, are recycled newspaper products that make cleaning up after the snakes easy. They also absorb odors fairly well and allow the snakes to burrow, which is important to hognoses, especially younger snakes.

 

Although wild Western hognoses inhabit regions of sandy, loose soils, it is not recommended that sand be used in their enclosures due to the threat of impaction. Some keepers prefer to feed their snakes in a separate enclosure or receptacle to prevent their possibly ingesting substrate.  

 

Western Hognose Snake Lighting and Temperature

 

Heat is especially important for proper digestion of food items, for gestation of eggs in females, and, when combined with light, it provides Western hognose snakes with seasonal breeding cues.  Failure to maintain proper temperatures can lead to health problems in your pet, and worse.

 

The upturned snout of the western hognose snake helps it to burrow.

For these diurnal snakes, full-spectrum lighting should be provided 14 to 16 hours per day during the spring and summer and eight to 10 hours during the autumn. There are a range of full-spectrum lighting products available at local pet retail outlets that will fulfill the requirements of your Western hognose. 

 

Under-tank heaters are available at pet stores and are specifically designed for use with most types of aquariums. One of these can be used to provide a hot spot basking area maintained at about 90 degrees Fahrenheit for your Western hognose. Be sure to get an appropriately sized heater to allow for a heat gradient—you don’t want it to heat more than one-third of the enclosure, so the snake can get away from the heat if desired—and never use medical heat pads found in pharmacies. While these may be adjustable, they can be potential fire hazards, or overheat the enclosure. Hot rocks are also to be avoided. The cooler end of the enclosure can be maintained in the high 70s.

 

Many Western hognose breeders house many snakes in rack systems. In a rack set-up, heat tape and a programmable thermostat or rheostat combination is most commonly used to provide heat. These can be purchased from reptile specialty stores or online. Heat tape is normally affixed to the shelving the enclosure sits on or in, and is a very good and easily manageable method for heating the enclosures in a rack.  

 

Western Hognose Snake Feeding

 

Established Western hognoses are usually eager feeders; some will come at you with open mouths appearing to say, “Feed me!” For stocky snakes, Western hognoses can be quick, and they often don’t follow the standard practice of striking at prey head-on—they will strike at food items from any direction. For these reasons, it’s best to use tongs, forceps or hemostats when feeding Western hognoses.

 

It is best to feed an appropriately sized meal—meaning a prey item that’s about the same diameter as the snake’s head—one to two times per week. Once it has been swallowed it should produce a noticeable lump, but not one that is so large that it is still noticeable 24 hours later. In the wild, Western hognoses consume a variety of prey items, including small rodents, lizards, amphibians and the eggs of ground-nesting animals. Pets do very well on a diet of pre-killed or frozen/thawed mice. Many Western hognose keepers prefer frozen/thawed rodents because they are easier for the snake to digest; at the cellular level, the food item has been broken down by about half. Also, as with pre-killed mice, the risk of your Western hognose being injured by a live mouse is eliminated.

 

When buying a neonate Western hognose, get one that has eaten three to four times on its own.  Ask before you buy the snake. Responsible breeders will not offer Western hognoses for sale unless they are established feeders. It is best to feed babies with small hemostats so you can better manipulate the prey item, and use it to draw the attention of the baby hognose. Most babies will readily accept as their first meal a thawed pinky mouse dipped in warm water (and it’s interesting to watch a young hognose drink the water dripping off the mouse just before it begins eating it). Repeating this a few times during the first several meals will result in a young Western hognose becoming an established feeder that looks forward to mealtime. 

 

Some hatchling Western hognoses can be challenging to get to accept mice. Scenting a thawed pinky mouse with canned tuna or salmon juice is easy and may encourage these snakes to eat. It usually gets good results, and it’s easy to wean the snakes off this form of scenting in a very short time. Sometimes “braining” a pinky works well, too, although this is not for the squeamish. It involves making a small pinhole in the skull of a frozen/thawed pinky, and squeezing a bit of brain matter out to smear on the mouse’s nose.

 

It is not recommended that toads be used as a scenting medium for Western hognoses. Using toads can introduce dangerous parasites to the snake, and it can also be difficult to wean small Western hognoses off toad-scented mice. Finding toads throughout the year can present problems, too.     

 

Western Hognose Snake Water

 

Even though wild Western hognoses inhabit areas that are semi-arid, pets still need a ready supply of clean water at all times. Change the water and wash the water bowl at least every week, and more often if the snake fouls the water.

 

Western Hognose Snake Handling and Temperament

 

The Western hognose is a docile, easy-to-handle snake. While individuals may exhibit spectacular bluffing displays as mentioned previously, these are not signs of aggression. Do not bother a snake that is exhibiting bluffing behavior, so as not to cause it undue stress. Wait until the snake has calmed down, and then handle it.

 

Western hognose bites are very rare, and typically occur due to a snake’s overeager feeding response. Some snakes will gently take food off hemostats, or they may prefer having food left in a quiet corner of the enclosure to eat at their leisure. Others will emerge from their enclosures ready for food with mouths open. No matter which type of behavior your animal displays, use hemostats, tongs or forceps to reduce the chance of an accidental bite.

 

Of the many Western hognoses I have produced or owned in my personal collection, over the number of years I have worked with these animals, I have been bitten only once. If a bite occurs, do not force the snake off by yanking on it, which could damage its jaws. Instead, pour a small capful of mint mouthwash onto the area the snake is biting. This is harmless to the snake and will result in it releasing its bite. Sometimes a hognose bite may lead to mild swelling at and around the bite site. This is best remedied by cleaning the location of the bite with soap and water and taking Benedryl within an hour after a bite occurs.

 

For decades, there has been discussion as to whether the Western hognose should be classified as a venomous reptile. It produces a proto-lipase enzyme cocktail in its saliva (as nearly all life forms do) that many herpetological authorities believe is used to help break down food. When someone uses the term “venomous,” they are referring not only to the type of enzyme cocktail injected into a victim, but also the system used in the delivery of venom. The Western hognose has a very primitive and inefficient delivery system, and its oral secretions (saliva) are harmless to humans. One might also look at its enlarged maxillary teeth as being used primarily to secure and hold food items.
