Bolyeriidae

The Bolyeriidae are a family of snakes native to Mauritius and a few nearby islands, especially Round Island. These snakes are also known as Mauritius snakes, Round Island boas, or splitjaw snakes. Sadly, they used to live on Mauritius but are no longer found there because of human actions and pigs that disturbed their habitat.

These snakes were once grouped with another family of snakes called the Boidae, but scientists now consider them to be their own special family. There are two different groups within this family, but only one species of these snakes is still alive today. Research shows that these snakes are most closely related to a group of snakes found in Asia called the genus Xenophidion.

Geographic range

These snakes live on the island of Mauritius and nearby small islands such as Serpent Island, Round Island, and Flat Island. They were once found on Mauritius itself, but are no longer seen there because of changes made by people and animals like pigs.

Genera

There are two groups of these special snakes, and both used to live on Mauritius and nearby islands. One group, called Bolyeria, hasn't been seen since 1975 and is thought to no longer exist. The other group, called Casarea, still lives only on Round Island.
