Spider-tailed Horned Viper
The spider-tailed horned viper (''Pseudocerastes urarachnoides''), also known as the spider-snake, is a species of viper, a venomous snake, in the family Viperidae and genus ''Pseudocerastes''. The genus is commonly known as "false-horned vipers". The species is endemic to western Iran and over the border region with Iraq, and was originally described in 2006. The head looks very similar to that of other ''Pseudocerastes'' species in the region, but the spider-tailed horned viper has a unique tail that has a bulb-like end that is bordered by long drooping scales that give it the appearance of a spider. (''Pseudocerastes urarachnoides'', new species). The tail tip is waved around and used to lure insectivorous birds to within striking range. Etymology The specific name, ''urarachnoides'', is derived from Ancient Greek ( tail + spider + like), and refers to this snake's spider-like tail tip, as does the common name, spider-tailed horned viper.

Caudal Luring
Caudal luring is a form of aggressive mimicry characterized by the waving or wriggling of the predator's tail to attract prey. This movement attracts small animals who mistake the tail for a small worm or other small animal. When the animal approaches to prey on the worm-like tail, the predator will strike. This behavior has been recorded in snakes, sharks, and eels. Mimicry The tail of a species may serve various functions, such as aggression, defense and feeding. Caudal luring behavior was first recorded in 1878 and is an instance of aggressive mimicry. Predators attract their prey by moving their caudal section to mimic a small animal, such as a worm, and attract prey animals. The prey is intrigued by caudal movement and will investigate assuming it is their own prey, and the predator will strike. Species Snakes Caudal luring behavior is found in over 50 different snake species. It is most common in boas, pythons, tropidophiids, colubrids and elapids of the genus ''Ac ...

Morelia Viridis
The green tree python (''Morelia viridis'') is a species of snake in the family Pythonidae. The species is native to New Guinea, some islands in Indonesia, and the Cape York Peninsula in Australia. First described by Hermann Schlegel in 1872, it was known for many years as ''Chondropython viridis''. As its common name suggests, it is a bright green snake that can reach a total length (including tail) of and a weight of , with females slightly larger and heavier than males. Living generally in trees, the green tree python mainly hunts and eats small reptiles and mammals. It is a popular pet, and numbers in the wild have suffered with large-scale smuggling of wild-caught green tree pythons in Indonesia. Despite this, the green tree python is rated as least concern on the IUCN Red List of endangered species. Taxonomy German naturalist Hermann Schlegel described the green tree python in 1872 as ''Python viridis'', from two specimens collected in the Aru Islands of Indonesia. His co ...

Acanthophis Praelongus
The northern death adder (''Acanthophis praelongus'') is a species of venomous snake in the family Elapidae. The northern death adder lives in Australia and Papua New Guinea. It hunts birds, amphibians, and small mammals both by day and night. Though it resembles a viper, it belongs to a group of snakes that includes cobras and mambas. Venom The venom of the northern death adder is highly potent against the human organism. It contains pre- and postsynaptic neurotoxins, possibly myotoxins and anticoagulants as well. An envenoming by this snake is very dangerous, and all bites should be treated as medical emergencies. Main effects include local pain and flaccid paralysis, death can be caused by respiratory failure. In the case of systemic effects of envenoming key treatment is based on antivenom applications ('Polyvalent Snake Antivenom (Australia - New Guinea)' CSL Limited, 'Death Adder Antivenom', CSL Limited). Habitat Northern death adders can be found in a wide range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthophis Antarcticus
The common death adder (''Acanthophis antarcticus'') is a species of death adder native to Australia. It is one of the most venomous land snakes in Australia and globally. While it remains widespread (unlike related species), it is facing increased threat from the ongoing Australian cane toad invasion. Taxonomy The common death adder was first described in 1802. The Common Death Adder feeds on frogs, lizards and birds and, unlike most Australian venomous snakes that actively search for prey, this snake sits in one place and waits for prey to come to it. Description The common death adder has a broad flattened, triangular head and a thick body with bands of red, brown and black with a grey, cream or pink belly. It can reach a maximum body length of . Death adders possess the longest fangs of any Australian snake. Unlike the common or European adder (''Vipera berus''), the common death adder is a member of the snake family Elapidae, rather than the family Viperidae The Viper ...

The massasauga (''Sistrurus catenatus'') is a rattlesnake species found in midwestern North America from southern Ontario to northern Mexico and parts of the United States in between. Like all rattlesnakes, it is a pit viper and is venomous. Three subspecies were recognized for more than a century, although research published in 2011 elevated two subspecies ''Sistrurus catenatus catenatus'' and ''Sistrurus catenatus tergeminus'', to full species: the eastern massasauga (''Sistrurus catenatus'') and the western massasauga (''Sistrurus tergeminus'').Kubatko, L.S.; Gibbs, H.L. & Bloomquist, E.W. 2011.
