Black-bellied swamp snake or marsh snake Hemiaspis signata

Warning: Venomous—treat bites from large specimens with caution

The marsh snake is olive to grey above with a grey to black belly. It has two narrow pale lines on each side of the face running through the upper lip and from the eye onto the neck. This snake preys on frogs and skinks and bears up to 20 live young. It is found throughout Brisbane in wet areas including rainforest, creeks and wetlands. This small snake can grow up to 50cm.

Recognisable by two distinctive narrow white lines on the face, the colour can range from pale olive to black top with a dark grey to black belly. Adults can grow to 70 cm in length, but most specimens are smaller than this. Their diet consists mainly of skinks and frogs.
