Gerrhopilidae
The Gerrhopilidae (Indo-Malayan blindsnakes) are a family of blindsnakes that contains at least 16 species in the genus ''Gerrhopilus'', and possibly others (the genus '' Cathetorhinus'' and the species known as either ''Malayotyphlops manilae'', ''Gerrhopilus manilae'', or ''Typhlops manilae'') as well. These blindsnakes are found in India (including the Andaman Islands), Sri Lanka, Nepal, Thailand, the Philippines, Indonesia (including Java, Ternate, Sulawesi, Halmahera, Waigeu, Salawati, Irian Jaya, and Bali), and Papua New Guinea. These blindsnakes were considered to be part of the family Typhlopidae and were formerly known as the ''Typhlops ater'' species group. In 2010, they were discovered to be distantly related to other typhlopids and separated into their own family. Gerrhopilidae, Xenotyphlopidae, and Typhlopidae are grouped together in the superfamily Typhlopoidea to emphasize their closer relationship to one another than to the other two families of scolecophidians ( ...

Scolecophidia
The Scolecophidia, commonly known as blind snakes or thread snakes, are an infraorder of snakes. They range in length from . All are fossorial (adapted for burrowing). Five families and 39 genera are recognized. The Scolecophidia infraorder is most likely paraphyletic. Taxonomy The infraorder name Scolecophidia derives from the two Ancient Greek words or σκώληκος (, genitive ), meaning "earthworm", and (), meaning "snake". It refers to their shape and fossorial lifestyle. Families Evolution Despite only having fossils as early as the Cretaceous, Scolecophidia itself likely originated in the Middle Jurassic, with Anomalepididae, Leptotyphlopidae, and Typhlopoidea diverging from one another during the Late Jurassic. Within Typhlopoidea, Gerrhopilidae likely diverged from the Xenotyphlopidae-Typhlopidae clade during the Early Cretaceous, and Xenotyphlopidae and Typhlopidae likely diverged from one another during the Late Cretaceous. Scolecophidians are believed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Typhlopidae
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands. The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. Typhlopids do not have dislocatable lower jaw articulations restricting them to prey smaller than their oral aperture. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, 18 genera are recognized containing over 200 species. Geographic range They are found in most tropical and many subtropical regions all over the world, particularly in Africa, Asia, islands in the Pacific, tropical America, and southeastern Europe.

Xenotyphlopidae
''Xenotyphlops'' is a genus of snakes, the only genus of the family Xenotyphlopidae, comprising two species found only in Madagascar. These snakes are also known as the Malagasy blind snake. Physical characteristics The family Xenotyphlopidae is composed of small blind snakes. These members lack cranial infrared receptors in pits or durface indentations. It is thought that these snakes used to have eyes but lost use of them over time. Members of the genus ''Xenotyphlops'' are distinguishable externally from the Typhlopidae by possessing a greatly enlarged and nearly circular rostral shield and a single enlarged anal shield. This shield is nearly vertical in a lateral aspect; as a result, the two species have a "bulldozer" appearance. ''Xenotyphlops'' get no larger than an earthworm and have translucent pink scales. ''Xenotyphlops'' species are internally unique in that they lack a tracheal lung and possess an unexpanded tracheal membrane. Like many other snake families they are ...

Leptotyphlopidae
The Leptotyphlopidae (commonly called slender blind snakes or thread snakes) are a family of snakes found in North America, South America, Africa and Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized. Description Relatively small snakes, leptotyphlopids rarely exceed in length; only ''Trilepida macrolepis'' and ''Leptotyphlops occidentalis'' grow larger. The cranium and upper jaws are immobile and no teeth are in the upper jaw. The lower jaw consists of a much elongated quadrate bone, a tiny compound bone, and a relatively larger dentary bone. The body is cylindrical with a blunt head and a short tail. The scales are highly polished. The pheromones they produce protect them from attack by termites.''Field Guide to Snakes of Southern Africa'' - Bill Branch (Struik 1988) Among these snakes is what is believed to be the world's smallest: '' L. carlae'' ( Hedges, 2008).

Anomalepididae
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. Common names include primitive blind snake and dawn blind snake. Description Species in the family Anomalepididae are small snakes, in total length (including tail) usually less than , with blunt heads and short, blunt tails. They are mainly burrowing snakes, and due to their life style their eyes are vestigial. Geographic range The family Anomalepididae is found from Southern Central America to northwestern South America. Disjunct populations occur in northeastern and southeastern South America. Genera ) Type genus In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name.
