Family Bolyeriidae

Bolyeriidae or mauritius snakes, round island boas and splitjaw snakes, is a family of of snakes native to Mauritius and a few islands around it, especially Round Island. In the past they also occurred on the island of Mauritius, but were extirpated there due to human influence and foraging pigs in particular. These snakes were formerly placed in the Boidae, but are now classed as a separate family. Currently, two monotypic genera are recognized, but only a single species is extant.


Both of these monotypic gena once inhabited Mauritius and/or a number of islands around it. However, Bolyeria hasn't been reported since 1975 and is believed to be extinct, while Casarae is presently known to survive only on Round Island.
