Twig snakes are among the few rear-fanged colubrids whose bite is highly venomous and potentially fatal. [4] The venom is hemotoxic, and although its effects are very slow, and bites are rare, no antivenom has been developed and several fatalities (such as Robert Mertens) have occurred.
The eastern indigo snake was first described by John Edwards Holbrook in 1842. For many years the genus Drymarchon was considered monotypic with one species, Drymarchon corais, with 12 subspecies, until the early 1990s when Drymarchon corais couperi was elevated to full species status according to the Society for the Study of Amphibians and Reptiles, in their official names list.
The snakes do not have a true venom gland, but they do have an analogous structure called the Duvernoy's gland derived from the same tissue. [4] Most subspecies are rear-fanged with the last maxillary teeth on both sides of the upper jaw being longer and channeled; [ 4 ] the notable exception is D. p. edwardsii , which is fangless. [ 7 ]
Despite the fact that many Australian snakes have unusually potent venom, wide access to antivenom, which is available for all dangerous species, [38] has made deaths exceedingly rare. It is believed that up to 1,500 definite or suspected snakebites occur in Australia each year, of which about 200 are serious enough to warrant antivenom therapy.
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:
Coloration ranges from charcoal gray, silver-gray, light yellow-beige, purplish, or infrequently albino, the ventral surface more pale. Coloration of the juvenile form is similar to that of the adult. Behavior ranges from lethargic in appropriate habitat to energetic, quickly seeking the cover of soil or leaf litter to avoid light.

There is currently no available antivenom for Atractaspis engaddensis. [12] This snake's fangs are able to be directed outside of its mouth, granting it the ability to side stab with a closed mouth. This makes capturing this snake particularly dangerous because it can unexpectedly bite sideways even when it is captured by the head to lock its ...
Crotalus cerastes, known as the sidewinder, horned rattlesnake or sidewinder rattlesnake, [3] is a pit viper species belonging to the genus Crotalus (the rattlesnakes), and is found in the desert regions of the Southwestern United States and northwestern Mexico.
