Homalopsidae

The Homalopsidae are a family of snakes with about 30 genera and more than 50 species. They are often called Indo-Australian water snakes, mudsnakes, or bockadams. These snakes live near water and are good swimmers. You can find them in rivers, swamps, and coastal areas in parts of Asia and Australia.

They have strong bodies and are mildly venomous. This venom helps them catch food but is not dangerous to humans.

Two special kinds of these snakes have unique looks: Erpeton has small, fleshy bumps on its nose, and Bitia has unusually large teeth on the roof of its mouth.

Some Homalopsidae snakes have interesting ways to move and hunt. For example, Cerberus species use a special crawling motion called sidewinding to travel over very slippery mud flats when the tide is out. Fordonia and Gerarda are the only snakes known to tear their food apart before eating it. They catch soft-shelled crabs and use their bodies like a coil to pull the crabs apart, making it easier to eat them.

Genera

The Homalopsidae family has about 30 groups, called genera. Each group has many types of snakes. Some of these genera are Bitia, Brachyorrhos, Calamophis, Cantoria, and Cerberus. Scientists named them in the 1800s. Others, like Djokoiskandarus, Gyiophis, and Karnsophis, were found more recently in the 2000s and 2010s.
