The rough-scaled death adder (Acanthophis rugosus) is a species of venomous snake in the family Elapidae. [3]
They are native to northern Australia, particularly Arnhem Land. Rough-scaled death adders are native to deserts. [4]
Death adders are generalists that feed upon small mammals, birds, lizards, and frogs. It is likely that allometric (size-related) shifts occur, with smaller specimens feeding more upon lizards and frogs and larger specimens including more mammals in their diets. Regional and interspecific differences in diet may also occur, although these are poorly documented. Like other species in the Elapidae family, they are ground hunters, and can wait for days and days in grass for food. [4]
Body slender to stout, unicolour or with a patterning of crossbands, with smooth or keeled scales in 19-23 rows at midbody, head angular with elevated supraocular scales, 6-7 supralabials with temporolabial scale present, eyes small with vertically elliptical pupils, tail slender, extremely distinct from the body, terminating in a flattened spinous tip which may be black or yellow and contrasts with the dorsal body colouration. [4]
Elapidae is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus Emydocephalus. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the 18 cm (7.1 in) white-lipped snake to the 5.85 m king cobra. Most species have neurotoxic venom that is channeled by their hollow fangs, and some may contain other toxic components in various proportions. The family includes 55 genera with some 360 species and over 170 subspecies.
The slender glass lizard is a legless lizard in the glass lizard subfamily (Anguinae). The species is endemic to the United States. Two subspecies are recognized. The lizard was originally believed to be a subspecies of the eastern glass lizard. Their name comes from their easily broken tail which they can break off themselves without ever being touched. It is difficult to find a specimen with an undamaged tail. The lizard eats a variety of insects and small animals, including smaller lizards. Snakes and other animals are known to prey on the species. Humans have a part in destroying their environment and killing their food supply with insecticides. The lizard is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though it is vulnerable in Iowa and endangered in Wisconsin. It is important to note that the streamlined, legless species is often confused with snakes. Glass Lizards, however, differ from snakes as they possess a moveable eyelid, which is absent in snakes. Another way to distinguish glass lizards from snakes is the presence of an external ear opening, which are absent in snakes.
Acanthophis is a genus of elapid snakes. Commonly called death adders, they are native to Australia, New Guinea and nearby islands, and are among the most venomous snakes in the world. Despite their common name, they are not adders at all and belong to the Elapidae family. The name of the genus derives from the Ancient Greek akanthos/ἄκανθος ('spine') and ophis/ὄφις ('snake'), referring to the spine on the death adder's tail.
Vipera berus, also known as the common European adder and the common European viper, is a species of venomous snake in the family Viperidae. The species is extremely widespread and can be found throughout much of Europe, and as far as East Asia. There are three recognised subspecies.
The eastern brown snake, often referred to as the common brown snake, is a species of highly venomous snake in the family Elapidae. The species is native to eastern and central Australia and southern New Guinea. It was first described by André Marie Constant Duméril, Gabriel Bibron, and Auguste Duméril in 1854. The adult eastern brown snake has a slender build and can grow to 2 m (7 ft) in length. The colour of its surface ranges from pale brown to black, while its underside is pale cream-yellow, often with orange or grey splotches. The eastern brown snake is found in most habitats except dense forests, often in farmland and on the outskirts of urban areas, as such places are populated by its main prey, the house mouse. The species is oviparous. The International Union for Conservation of Nature classifies the snake as a least-concern species, though its status in New Guinea is unclear.
The sand goanna is a species of large Australian monitor lizard, also known as Gould's monitor, sand monitor, or racehorse goanna.
Pseudechis is a genus of venomous snakes in the family Elapidae. It contains the group of elapid species commonly referred to as the black snakes. Species of Pseudechis are found in every Australian state with the exception of Tasmania, and some species are found in Papua New Guinea. They inhabit a variety of habitat types, from arid areas to swampland. All species are dangerous and can inflict a potentially lethal bite. Most snakes in this genus reach about 2 m (6.6 ft) in total length, and vary in colour. Some species are brown, whereas others are black. The most recognisable and widespread species in the genus are the red-bellied black snake and the mulga snake. These snakes feed on lizards, frogs, birds, small mammals, and even other snakes. All species of Pseudechis lay eggs with the exception of the red-bellied black snake P. porphyriacus which is viviparous. The genus Pailsus is a synonym of Pseudechis, and more work is needed to understand species limits among the smaller species of the group.
The common death adder 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, it is facing increased threat from the ongoing Australian cane toad invasion.
The desert death adder is a species of snake native to Australia and is one of the most venomous land snakes in the world. The desert death adder is under threat due to the destruction of habitat.
Paroplocephalus is a genus of venomous snake in the family Elapidae. The genus is monotypic, containing only the species Paroplocephalus atriceps, the Lake Cronin snake. The species is endemic to western Australia.
Echiopsis curta is a terrestrial, elapid species of snake, also commonly known from the Aboriginal name as the bardick. It is a short, highly venomous snake with variable color which is mainly nocturnal, reaching a maximum length of 57 cm. It is endemic to Australia, most commonly found in three distinct populations through southern Australia. They are considered venomous to humans, however there is very little information. Their population is decreasing due to habitat degradation and destruction but considered least concern on the IUCN Red List.
The blue-bellied black snake, also known commonly as the spotted black snake, is a species of venomous snake in the family Elapidae. The species is native to Australia.
The curl snake is a species of venomous, heavily built snake in the family Elapidae. The species, which is native to Australia, is also known more commonly in Western Australia as the myall snake. The curl snake is often confused with a similar species named the Ord curl snake.
Anchieta's cobra, sometimes referred to as the Angolan cobra, is a species of venomous snake in the family Elapidae. The species is native to Southern Africa.
Ichnotropis capensis is a species of African lizard, which is native to the southern Afrotropics. It is the type species for the genus Ichnotropis, and is commonly called the Cape rough-scaled lizard due to them being found in southern Africa's Cape region. They are also called ornate rough-scaled lizard or Smith's rough-scaled sand lizard. The small lizards are terrestrial and occur in grassland, desert and brush areas of southern Africa.
The northern death adder is a species of venomous snake in the family Elapidae.
The Barkly Tableland death adder is a species of venomous snake in the family Elapidae. The exact distribution of the species is unclear, but suitable habitat for the plains death adder consists of flat, treeless, cracking-soil riverine floodplains. Based on the presence of suitable habitat, the potential geographic range for this species extends from Western Queensland, across the north of the Northern Territory to north-east Western Australia. Disjunct populations of the plains death adder are known to occur in the Mitchell Grass Downs of western Queensland, the Barkly Tableland on the Northern Territory/Queensland border and east of Darwin in the Northern Territory. The snake is named after former Prime Minister of Australia Bob Hawke.
The Kimberley death adder is a species of venomous snake in the family Elapidae native to northwestern Australia.
The Pilbara death adder, also known commonly as Wells' death adder, is a species of venomous snake in the family Elapidae. The species is one of the eight members of the genus Acanthophis, a genus which is found throughout northwestern and southwestern Australia and some parts of southern Papua New Guinea. The species Acanthophis wellsi is endemic to Western Australia.
Pachydactylus barnardi, also known commonly as Barnard's rough gecko or Barnard's thick-toed gecko, is a species of lizard in the family Gekkonidae. The species is indigenous to Southern Africa.
