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 (' ...

Dipsadinae
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). Species of the subfamily Dipsadinae are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 member species. Dipsadinae are an ecologically and morphologically diverse group of mostly small to moderate-sized snakes, typically less than in total length. Some are arboreal, but others are aquatic or terrestrial and may even burrow. Most are oviparous. Many eat frogs or lizards, and some consume mammals and birds. Several genera (e.g. '' Adelphicos'', '' Atractus'', '' Geophis'', '' Dipsas'', '' Ninia'', '' Sibon'', '' Sibynomorphus'', '' Tropidodipsas'') are specialized feeders on gooey and slimy prey, such as frog eggs, earthworms, snails, and slugs. Almost all species are completely harmless to humans, although a few genera (e.g. '' Borikenophis'', '' Cubophis'', '' Heterodon'', '' Hydrodynastes'', ''Philodryas'') ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Richard Thomas (herpetologist)
John Paul Richard Thomas (born 1938) is an American taxonomist and systematist, and retired professor of herpetology and evolution at University of Puerto Rico-Rio Piedras (San Juan, Puerto Rico). (Kindle edition). (hardcover). He described several species new to science, mostly amphibians and reptiles, from throughout the Caribbean islands including the common coquí (''Eleutherodactlys coqui)'', the national animal of Puerto Rico.

Later, he went to Louisiana State University and obtained a PhD in 1976. Research Thomas' research has focused mostly on amphibians and reptiles, spanning several fields from natural history to systematics and evolution. His studies have yielded descriptions of new species of dwarf geckos (''Sphaerodactylus''), blind snakes ( Scolecophidia), and rain frogs (''Eleutherodactylus''). ...
