The recent fossil record of Eunectes is relatively sparse compared to other vertebrates and other genera of snakes. The fossil record of this group is effected by an artifact called the Pull of the Recent. [6] Fossils of recent ancestors are not known, so the living species 'pull' the historical range of the genus to the present.
This is a list of extant snakes, given by their common names. Note that the snakes are grouped by name, and in some cases the grouping may have no scientific basis.
Asian cobras, coral snakes, and American coral snakes also appear to be monophyletic, while African cobras do not. [12] [13] The type genus for the Elapidae was originally Elaps, but the group was moved to another family. In contrast to what is typical of botany, the family Elapidae was not renamed.
The Boidae, commonly known as boas or boids, [3] are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium ...
Colubridae (/ k ə ˈ l uː b r ɪ d iː /, commonly known as colubrids / ˈ k ɒ lj ʊ b r ɪ d z /, from Latin: coluber, 'snake') is a family of snakes. With 249 genera, [2] it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. [1]
The majority of snakes eat a variety of prey animals, but there is some specialization in certain species. King cobras and the Australian bandy-bandy consume other snakes. Species of the family Pareidae have more teeth on the right side of their mouths than on the left, as they mostly prey on snails and the shells usually spiral clockwise.
The following is a list of the classes in each phylum of the kingdom Animalia. There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by ...
