  Map 40  Tropidechis carinatus



Tropidechis lives in wet forested areas and scrub, where they mostly hunt at night. These snakes are also not uncommonly found in low scrub and bushes, which is unusual for elapids. Of the Australian elapids, the genus Hoplocephalus is the only other that is arboreal, and rarely tiger snakes (Notechis sp.).

With a body length of under 1 m, the fangs are relatively long (up to 5 mm). Tropidechis is very aggressive when threatened and even under slight provocation will strike fiercely and repeatedly.



Tropidechis possesses only small quantities of venom and, compared to the most dangerous Australian species, the venom is only moderately toxic. However, there is one documented fatality.
