Pareidae
Pareidae is a small family of snakes found largely in southeast Asia, with an isolated subfamily endemic to southwestern India. It encompasses 42 species in four genera divided into two subfamilies: Pareinae and Xylophiinae. Both families are thought to have diverged from one another during the early-mid Eocene, about 40-50 million years ago. Pareidae was once considered a subfamily of Colubridae (called "Pareatinae"), but since 2013 it is known that pareids are not closely related to colubrids. The correct spelling is Pareidae, not Pareatidae. Members of the subfamily Pareinae are active, predatory snakes. Many are snail A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial molluscs, terrestrial pulmonate gastropod molluscs. However, the common name ''snail'' is also used for most of the members of the molluscan class Gas ...-eating snakes that have asymmetrical lower jaws, allowing them to pry the soft bodies of snails from their sp ...

Snakes Of Asia
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, 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 only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times 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 ...

Aplopeltura
''Aplopeltura'' is a genus of snakes of the family Pareidae. It contains a single species, ''Aplopeltura boa'', the blunthead slug snake or blunt-headed slug-eating snake. It is a small, non-venomous snake. The species can be found in southern Thailand, Malaysia, Indonesia, Brunei and the Philippines. ''A. boa'' eats mainly snails, especially operculate species. Their jaws are more mobile than those of most other vertebrates. With their mandibles, they cut the operculum off from their prey with a unique "sawing" motion. ''A. boa'' has been observed performing simple death feigning behavior. The snake rolls itself into a spiral with its belly up, staying still until the threat leaves. Unlike other death feigning snakes, ''A. boa'' does not emit a foul odor or open its mouth.

Colubridae
Colubridae (, commonly known as colubrids , from , 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. Colubrid snakes are found on every continent except Antarctica. Description Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters. A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals. However, the bites of some can escalate quickly to emergency situations. Furthermore, within the Colubridae, the South African boomslang and twig snakes, as well as the Asian keelback snakes (' ...

Iwasaki's Snail-eater
Iwasaki's snail-eater (''Pareas iwasakii)'' is a species of snake in the family Pareidae. The species is endemic to the Yaeyama Islands in the southern Ryukyu Islands, Japan. Etymology The specific name, ''iwasakii'', is in honor of Japanese meteorologist Takuji Iwasaki. Habitat The preferred natural habitats of ''P. iwasakii'' are forest, shrubland, and grassland. Ecology ''P. iwasakii'' is a snail-eating specialist; even newly hatched individuals feed on snails. It has asymmetric dentition on its jaws, with more teeth on the right mandible (about 25 teeth compared to 15 teeth on the left mandible) which facilitates feeding on snails with dextral (clockwise coiled) shells. A consequence of this asymmetry is that ''P. iwasakii'' is much less adept at preying on sinistral (counterclockwise coiled) snails. It systematically directs its attack on snails from the right in order to insert its lower jaw into the shell opening. The selection pressure of this predator on snails of ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Alfred Romer
Alfred Sherwood Romer (December 28, 1894 – November 5, 1973) was an American paleontologist and biologist and a specialist in vertebrate evolution. Biography Alfred Romer was born in White Plains, New York, the son of Harry Houston Romer and his wife, Evalyn Sherwood. He was educated at White Plains High School. He studied at Amherst College for his Bachelor of Science Honours degree in biology, then at Columbia University for an M.Sc. in biology and a doctorate in zoology in 1921. Romer joined the department of geology and paleontology at the University of Chicago as an associate professor in 1923. He was an active researcher and teacher. His collecting program added important Paleozoic specimens to Chicago's Walker Museum of Paleontology. In 1934 he was appointed professor of biology at Harvard University. In 1946, he became director of the Harvard Museum of Comparative Zoology (MCZ). Romer was elected to the American Academy of Arts and Sciences in 1937. In 1951, he w ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
