Achalinus niger, common name black odd-scaled snake [1] [2] [3] or black burrowing snake, [4] is a snake in family Xenodermatidae [5] that is endemic to Taiwan. [1] [2] [3] [6]
This Taiwan endemic is widespread at elevations of 1,000–3,000 m (3,300–9,800 ft) asl. [1] [2] [3] Genetic analyses have indicated three distinct clades, a northern one from the Xueshan Range, a southern one from the Alishan Range and southern Central Mountain Range, and Meifeng, a small but very distinct location at the middle of the Central Mountain Range. [7]
Achalinus niger is a small snake growing to a total length of about 80 cm (31 in). The whole body is iridescent under light. Head is small, oval, and without distinct neck. Body is slender and tail is moderately short. Eyes are small, bead-like; iris is black and indistinct. Upper head, body and tail is uniform olive, grayish tan, or black. Mid-dorsal row of scales on body and tail show a dark longitudinal line. Ventral surface is olive-yellow or dark gray. The young are usually black. [3]
It is a nocturnal and terrestrial snake that preys on earthworms, slugs, and frogs. It is non-venomous and not aggressive. [3] Female lays about seven eggs weighing about 1.6 g (0.056 oz) each. [3] [4]
Achalinus niger occurs in forests, and sometimes, in caves. It is often found in dark and wet microhabitats such in leaf litter or rotten logs. [1] [3]
No significant threats are known. [1] It is a Class II protected species. [1] [3]
Pantherophis obsoletus – also known as the western rat snake, black rat snake, pilot black snake, or simply black snake – is a non-venomous species of Colubridae found in central North America. No subspecies are currently recognized. Its color variations include the Texas ratsnake. Along with other snakes of the eastern United States, like the eastern indigo snake or the eastern racer, it is called 'black snake'.
The slender glass lizard is a legless lizard in the family Anguidae. 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.
Tiger snakes are a highly venomous snake species found in the southern regions of Australia, including its coastal islands, such as Tasmania. These snakes are often banded like a tiger, and highly variable in their colour and forms in their regional occurrences. All populations are in the genus Notechis, and their diverse characters have been described in further subdivisions of this group; they are sometimes described as distinct species and/or subspecies.
The woma python, also known commonly as Ramsay's python, the sand python, and simply the woma, is a species of snake in the family Pythonidae, endemic to Australia. Once common throughout Western Australia, it has become critically endangered in some regions.
The Namaqua chameleon is a ground-living lizard found in the western desert regions of Namibia, South Africa and southern Angola.
Atheris barbouri is a small and rare terrestrial species of viper endemic to the Uzungwe and Ukinga mountains of south-central Tanzania in Africa. No subspecies are recognized.
The Chinese cobra, also called the Taiwan cobra, is a species of cobra in the family Elapidae, found mostly in southern China and a couple of neighboring nations and islands. It is one of the most prevalent venomous snakes in China and Taiwan, which has caused many snakebite incidents to humans.
The blackbelly salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are rivers, intermittent rivers, and freshwater springs. It is threatened by habitat loss.
The Balkan whip snake is a species of snake in the family Colubridae. It is found in Italy, Greece and most of the Balkan countries where its natural habitats are Mediterranean-type shrubby vegetation, pastureland, plantations and rural gardens. It is threatened by habitat loss in parts of its range but overall is assessed by the IUCN as being of "least concern".
Carphophis amoenus, commonly known as the worm snake, is a species of nonvenomous colubrid endemic to the eastern United States. C. amoenus can be found east of the Mississippi, from southwest Massachusetts south to southern Alabama west to Louisiana and then north to Illinois. This species of snake protects a large range, and normally prefers a moist habitat in the rocky woodlands, under rotten wood of logs and stumps. Though this snake is quite abundant over its range, it is rarely seen because of its dormant lifestyle and where it usually resides. This snake is most common on the edges or in the ecotonal areas of open to thick woodlands, and the borders of wetlands. It may also be found in the grasslands next to woodlands. The best chance to spot it is after heavy rains, when its small size and distinct color make it easy to spot. This species prefers moist soil inhabited by earthworms, which are its main prey, so the soil needs to be sufficiently moist. The snake's skin naturally evaporates water; so the soil needs to be moist enough to offset this. C. amoenus is mostly found under rocks and in sufficient leaf litter during the extreme daytime heat.
Plagiopholis styani, also known by the common name Chinese mountain snake, is a species of colubrid snake. Its type locality is Kuatun in Wuyishan, Fujian. It is found in southern and central China, Taiwan, and northern Vietnam. It is an uncommon species, and very rare in Taiwan. It is named after Frederick William Styan, a Shanghai-based English tea merchant and ornithologist.
Achalinus jinggangensis, commonly known as Zong's odd-scaled snake, is a species of snake in the family Xenodermatidae. The species is endemic to the Jinggang Mountains of China.
Lycodon cardamomensis, also known as the Cardamom Mountains wolf snake, is a species of non-venomous colubrid snakes found in south-western Cambodia and eastern Thailand.
Nephrurus levis, commonly known as the three-lined knob-tailed gecko, smooth knob-tailed gecko, or common knob-tailed gecko, is a native Australian gecko species. The smooth knob-tailed gecko is part of the Carphodactylidae family, a family endemic to Australia. A common, alternative, name for this family is barking geckos due loud barks they make during threat displays, which includes swaying their bodies, winding their tail and attacking with an open mouth. There are multiple sub-species of Nephrurus levis, these include N.l. levis, N.l. occidentalis and N.l. pibarenis. Its aboriginal name is Illchiljera.
Achalinus formosanus, common name Formosan odd-scaled snake or Taiwan burrowing snake, is a non-venomous snake in family Xenodermidae that is found in Taiwan and in the southern Ryukyu Islands (Japan).
Rhabdophis swinhonis is a species of snake in the subfamily Natricinae of the family Colubridae. The species is endemic to Taiwan. It is also known commonly as the Taiwan keelback and Swinhoe's grass snake.
The variable fat-tailed gecko or burrow-plug gecko is a diplodactylid gecko endemic to central and arid inland areas of Australia. Widespread across the continent, the variable fat-tailed is most commonly found in sandy desert habitats dominated by Spinifex grasses. They have also been bred in captivity by zoos and as pets.
Uropeltis shorttii, also known as the Shevaroy Hills earth snake or Shortt's shieldtail snake, is a species of non-venomous snake endemic to the Southern Eastern Ghats of India. This species was first described as Silybura shorttii by Richard Henry Beddome, in 1863. It is found only in the Shevaroy Hills of Salem district in Tamil Nadu state in South India. This species was misclassified into Uropeltis ceylanica, a snake endemic to the Western Ghats, for a long time, till a recent taxonomic study proved it to be a distinct species with a very narrow geographic range. It is a burrowing snake, presumed to be nocturnal; feeding on soft-bodied worms. Becomes active during the rains. This is a "data deficient" species, as it is yet to assessed for its conservation status.
