Xenotyphlops is an ancient group that diverged from other blind snakes during the Cretaceous, following the separation of Madagascar from India.On the newly-isolated Madagascar, the ancestral Xenotyphlopidae and Typhlopidae diverged from one another; Typhlopidae dispersed worldwide from Madagascar while leaving behind a single Malagasy genus (Madatyphlops), while the Xenotyphlopidae remained ...

The Scolecophidia, commonly known as blind snakes or thread snakes, [2] are an infraorder [2] of snakes. [3] They range in length from 10 to 100 centimeters (4 to 40 inches). All are fossorial (adapted for burrowing). [ 4 ]
All species in the family Typhlopidae are fossorial and feed on social fossorial invertebrates such as termites and ants. The tracheal lung is present and chambered in all species. One species, the Brahminy's blind snake, is the only unisexual snake, with the entire population being female and reproducing via parthenogenesis.

Madatyphlops is a genus of snakes in the family Typhlopidae. Madatyphlops may represent a surviving clade of the ancestral Typhlopidae, which are thought to have originated on Madagascar during the Cretaceous , before later dispersing to mainland Africa and then worldwide.
Madagascar's varied fauna and flora are endangered by human activity. [24] Since the arrival of humans around 2,350 years ago, Madagascar has lost more than 90 percent of its original forest. [25] This forest loss is largely fueled by tavy ("fat"), a traditional slash-and-burn agricultural practice imported to Madagascar by the earliest ...
The Anomalepididae are a family of nonvenomous snakes, native to Central and South America. They are similar to Typhlopidae, except that some species possess a single tooth in the lower jaw. Currently, four genera and 15 species are recognized. [2] Common names include primitive blind snake [2] and dawn blind snake.
