Tropidechis

Tropidechis is a small genus in the family Elapidae, the front-fanged venomous snakes that include cobras, mambas, taipans, and most of Australia's terrestrial snake fauna. The genus is best known for the rough-scaled snake, Tropidechis carinatus, found along the eastern coast of Australia. As elapids, members have fixed front fangs and potent venom, which sets the genus apart from the superficially similar but harmless keelbacks it often shares habitat with.

The rough-scaled snake lives in wet forests, rainforest margins, and well-watered gullies of coastal eastern Australia, often near creeks and damp ground. The defining feature is its strongly keeled body scales, which give the snake a rough, ridged texture and a matte appearance rather than a glossy sheen. The coloration is typically olive to brown with darker crossbands or blotches, and the build is moderate, with adults usually under a meter in length. This keeled, banded look is exactly why it is so often confused with the non-venomous keelback, Tropidonophis mairii, a mistake that can have serious consequences.

This snake is venomous and considered dangerous to humans. Its venom contains neurotoxins and components that can affect blood clotting and muscle tissue, and bites are treated as a medical emergency. It hunts frogs, lizards, small mammals, and other small prey, and like many Australian elapids it gives birth to live young rather than laying eggs. It is not aggressive but will defend itself if cornered or handled. Never handle a wild snake you suspect is a rough-scaled snake, and never rely on the keelback resemblance to judge safety. If a bite occurs, treat it as life-threatening, keep the person still, and seek emergency care immediately, in the US via Poison Control at 1-800-222-1222 or local emergency services.
