Dwarf crocodiles are found in West and West-central Africa, and are one of the least known crocodilians in the wild. Adult males reach 1.7 to 1.9 metres (5.6 to 6.2 feet), although it seems that some individuals (males) are restricted to even smaller sizes. There are two subspecies (at least) and this may explain differences in temperament, appearance and maximum size. They have a similar ecology to the dwarf caimans of South America, being primarily nocturnal and spending much of their time during the day in burrows or under tree roots. Hatchlings tend to be exceptional at climbing, so ensure that your enclosure is escape proof! Opinion about this species' temperament varies: whilst many believe this to be one of the more docile species, others have found adults to be extremely aggressive and territorial animals which do not get on well with other crocodilians - being quite capable of killing animals larger than themselves. In the wild, this species feeds on prey such as crustaceans and molluscs (plus fish and amphibians), and they have very broad and powerful crushing jaws more like a caiman or alligator which are capable of inflicting a very serious bite. Despite their smaller size, some owners caution others about this species because of its potentially aggressive nature - in other words, don't be fooled by a crocodilian simply because it reaches a smaller adult size. However, much of an adult's nature can also be influenced by the way it is raised. 

Other crocodilian species may be available legally for purchase in captivity, and this will vary depending on the country you live in. In Australia, for example, both the saltwater crocodile (Crocodylus porosus) and Johnston's crocodile (Crocodylus johnstoni) can be purchased with appropriate documentation. However, always find out more about the species you intend to buy before making the purchase. Saltwater crocodiles, for example, are one of the most aggressive of all crocodilian species and have a maximum size exceeding 6 metres (18 to 19 feet) which makes them totally unsuitable for just about anyone outside of a zoological park or a crocodile farm. Just because a species is available to buy, that does not mean it is suitable as a pet or even suitable for captivity period. Pet stores and private individuals will, and often do, try and sell anything to someone they consider gullible enough.
