Collared Blind Snake
The collared blind snake (''Habrophallos collaris'') is a species of snake in the family Leptotyphlopidae. It was previously placed in the genus Leptotyphlops and then Epictia, until in 2019 a phylogenetic analysis found it couldn't be placed in either genus, and a new genus was created for it. It is Monotypic taxon, monotypic in the genus ''Habrophallos''. References Leptotyphlopidae Reptiles described in 1977 Taxobox binomials not recognized by IUCN {{Scolecophidia-stub ...

Snake
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaen ...

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).

Leptotyphlops
''Leptotyphlops'' is a genus of nonvenomous blind snakes, commonly known as slender blind snakes and threadsnakes, in the family Leptotyphlopidae. The genus is endemic to and found throughout Africa. Eleven species have been moved to the genus ''Trilepida'', and other species have been moved to the genera ''Epacrophis'', ''Epictia'', '' Mitophis'', '' Myriopholis'', ''Namibiana'', '' Rena'', ''Siagonodon'', '' Tetracheilostoma'', and ''Tricheilostoma''. Description Most species of ''Leptotyphlops'' look much like shiny earthworms. They are generally black, grey, or blackish-brown and their scales give them a segmented appearance. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies. Behavior All blind snakes including those of the genus ''Leptotyphlops'' are burrowing snakes, spend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epictia
''Epictia'' is a genus of snakes in the family Leptotyphlopidae. The genus is native to South America, Central America, and Mexico. Taxonomy Prior to 2009 all species of ''Epictia'' were placed in the genus ''Leptotyphlops''. Species The genus ''Epictia'' contains the following 44 species which are recognized as being valid: www.reptile-database.org. *'' Epictia albifrons'' *'' Epictia albipuncta'' *'' Epictia alfredschmidti'' *'' Epictia amazonica'' *'' Epictia antoniogarciai'' *'' Epictia ater'' *'' Epictia australis'' – Freiberg's blind snake *'' Epictia bakewelli'' – Bakewell's blind snake *'' Epictia borapeliotes'' *'' Epictia clinorostris'' *'' Epictia columbi'' – San Salvador blind snake *'' Epictia diaplocia'' – common Peru blind snake *'' Epictia fallax'' *'' Epictia goudotii'' *'' Epictia guayaquilensis'' *'' Epictia hobartsmithi'' *'' Epictia magnamaculata'' *'' Epictia martinezi'' *'' Epictia melanura'' – dark blind snake *'' Epictia mun ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Reptiles Described In 1977
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...
