Documented deaths resulting from snake bites are uncommon. Nonfatal bites from venomous snakes may result in the need for amputation of a limb or part thereof. Of the roughly 725 species of venomous snakes worldwide, only 250 are able to kill a human with one bite. Australia averages only one fatal snake bite per year. In India, 250,000 ...
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.
The common watersnake mates from April through June. It is ovoviviparous (live-bearing), which means it does not lay eggs like many other snakes. Instead, the mother carries the eggs inside her body and gives birth to free-living young, each one 19–23 cm (7 + 1 ⁄ 2 –9 in) long. [25]
A survey in southern Africa from 1957–1979 recorded 2,553 venomous snakebites, 17 of which were confirmed as eastern green mambas. Of these 17, 10 had symptoms of systemic envenomation, though no victims died. [29] The snake tends to bite repeatedly, [28] and one bite can contain 60–95 mg of venom by dry weight. [30]
They typically lay 12 eggs in sand or other protected areas and leave the eggs to incubate unprotected. Clutches of five to 22 eggs have been observed. The eggs are elliptical, leathery, rough, sticky, and up to 70 mm (2 + 3 ⁄ 4 in) long. [17] The eggs typically hatch in August or September. Baby bull snakes are 20–46 cm (7.9–18.1 in) at ...
The common death adder (Acanthophis antarcticus) is a highly venomous snake species with a 50–60% untreated mortality rate. [87] It is also the fastest striking venomous snake in the world. [88] A death adder can go from a strike position, to strike and envenoming their prey, and back to strike position again, in less than 0.15 seconds. [88]
They also eat birds as well as bird eggs and nestlings. They suffocate their prey by constriction, though harmless smaller mouthfuls may be eaten alive without constriction, or simply crushed on eating by jaws. Juveniles mainly eat lizards and arthropods, later small rodents. Other snakes and lizards are taken, but only found rarely in adult prey.
Dasypeltis is a genus of snakes, also known commonly as egg-eating snakes or egg-eaters, in the subfamily Colubrinae of the family Colubridae. The genus is one of only two taxonomic groups of snakes known to have adapted to feed exclusively on eggs (the other being the genus Elachistodon ).
