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. Contents:
Heterodon is a genus of harmless colubrid snakes endemic to North America. [1] They are stout with upturned snouts and are perhaps best known for their characteristic threat displays. Three species are currently recognized. [ 2 ]
The corn snake is named for the species' regular presence near grain stores, where it preys on mice and rats that eat harvested corn (). [9]The Oxford English Dictionary cites this usage as far back as 1675, whilst other sources maintain that the corn snake is so-named because the distinctive, nearly-checkered pattern of the snake's belly scales resembles the kernels of variegated corn.
It has been suggested that all snakes may be venomous to a certain degree, with harmless snakes having weak venom and no fangs. [84] According to this theory, most snakes that are labelled "nonvenomous" would be considered harmless because they either lack a venom delivery method or are incapable of delivering enough to endanger a human.
The Pythonidae, commonly known as pythons, are a family of nonvenomous snakes found in Africa, Asia, and Australia. Among its members are some of the largest snakes in the world. Ten genera and 39 species are currently recognized. Being naturally non-venomous, pythons must constrict their prey to induce cardiac arrest prior to consumption.
The eastern hog-nosed snake [3] (Heterodon platirhinos), is a species of mildly venomous rear-fanged snake in the family Colubridae. The venom is specifically adapted to amphibian prey and is harmless to humans. However, some people may have an allergic reaction, and experience local swelling and other symptoms.
This species is classified as Vulnerable (VU) on the IUCN Red List of Threatened Species with the following criteria: C1+2a(i) (v3.1, 2001). [9] A species is listed as such when the best available evidence indicates that the population size is estimated to number fewer than 10,000 mature individuals, a decline of at least 10% is estimated to continue within 10 years or three generations ...
Both milk snakes and coral snakes possess transverse bands of red, black, and yellow. Experts now recognize that common mnemonics that people use to distinguish between the deadly coral snake and the harmless milk snake are not 100% reliable. Some coral snakes do not have the typical banding colors or patterns. [14]
