Behaviour :

C. tennentii is diurnal, and therefore is usually only active in the day. Very little is actually known about the behaviour of this unusual lizard.

Habitat  :

C. tennentii is found in the wet tropical montane cloud forests of the Knuckles mountains in Sri Lanka at elevations of 760–1,220 m (2,490–4,000 ft). It has also been recorded in several other forest habitats.

Diet :

C. tennentii is reported to feed on insects and other small arthropods.

Reproduction :

C. tennentii lays eggs and is a sexually reproducing animal.

Threats :

Threats to C. tennentii include deforestation, pesticides, climate change, forest fires, and bioaccumulation. Much of its habitat has been cleared for illegal logging and the cardamom, coffee, tea, and rubber plantations over the past two centuries.

Captivity :

As of 2006, the leaf-nosed lizard is protected because of its endangered status, making its trade illegal.

Conservation efforts :

In 2000, areas above 1,067 m (3,501 ft) above sea level were protected and labeled as conservation forest. Cardamom cultivation had to be abandoned in this area. However, rather than natural regeneration, the cardamom range was taken over by invasive weeds such as mistflower (Eupatorium riparium) and lantana (Lantana camara). C. tennentii was placed on the endangered list by the IUCN in 2006.
