Homalopsidae

The Homalopsidae are a family of snakes which contains about 30 genera and more than 50 species. They are commonly known as Indo-Australian water snakes, mudsnakes, or bockadams. These snakes live near water and are good swimmers, often found in rivers, swamps, and coastal areas across parts of Asia and Australia.

They are typically stout-bodied water snakes, and all are mildly venomous. This venom helps them catch prey but is not dangerous to humans in large amounts. Two special kinds of these snakes stand out because of their 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 includes around 30 different groups, called genera, each with several species of snakes. Some of these genera are Bitia, Brachyorrhos, Calamophis, Cantoria, and Cerberus, named by scientists from different years starting in the 1800s. Others, like Djokoiskandarus, Gyiophis, and Karnsophis, were identified more recently in the 2000s and 2010s.
