Coelognathus radiatus, commonly known as the radiated ratsnake, copperhead rat snake, or copper-headed trinket snake, is a nonvenomous [2] [3] species of colubrid snake.
These snakes are usually defensive in nature which makes it hard to catch or control them. [4] [5]
Type locality: Java [7]
Rat snakes are members – along with kingsnakes, milk snakes, vine snakes and indigo snakes – of the subfamily Colubrinae of the family Colubridae. They are medium to large constrictors and are found throughout much of the Northern Hemisphere. They feed primarily on rodents. Many species make attractive and docile pets and one, the corn snake, is one of the most popular reptile pets in the world. Like all snakes, they can be defensive when approached too closely, handled, or restrained. However, rat snake bites are not dangerous to humans. Like nearly all colubrids, rat snakes pose no threat to humans. Rat snakes were long believed to be completely nonvenomous, but recent studies have shown that some Old World species do possess small amounts of venom, though the amount is negligible relative to humans.
Pantherophis obsoletus, also known commonly as the western rat snake, black rat snake, pilot black snake, or simply black snake, is a nonvenomous species of snake in the family Colubridae. The species is native to central North America. There are no subspecies that are recognized as being valid. Its color variations include the Texas rat snake. Along with other snakes of the eastern United States, like the eastern indigo snake and the eastern racer, it is called “black snake”.
The beauty rat snake, also called the beauty ratsnake, the beauty snake, or the cave racer, is a species of snake in the family Colubridae. The species is native to the eastern and southeastern regions of Asia. It is a long, thin, semi-arboreal species of snake with several recognized subspecies. This constrictor feeds on rodents, and though it is favored in some locations as a natural pest control or pet, it is also considered an invasive species in other locations.
Pantherophis is a genus of nonvenomous colubrid snakes endemic to central and eastern regions of North America. It consists of the North American ratsnakes, the foxsnakes, and the cornsnakes. The genus, which contains 10 recognized species, first appeared in the fossil record in the Middle Miocene around 16.3 million years ago. They are a large terrestrial snake genus that lack subocular scales. Originally classified in the genus Elaphe, phylogenetic studies have found this taxon to be closely related to Pituophis. As with all snakes Pantherophis is an obligate faunivore with a diet that consists of small mammals, birds, reptiles and amphibians, and even insects. While many species conservation status is categorized as "least concern", many local populations in some species have declined where some places have them listed as federally protected. The corn snake is a popular pet reptile, due to the availability of captive-bred animals, their low maintenance and calm disposition, and the variety of color morphs. There are other species of Pantherophis that are in the pet trade, though are not as popular as the corn snake.
Boiga multomaculata, also called the many-spotted cat snake, large-spotted cat snake and marbled cat-eyed snake, is a species of rear-fanged colubrid snakes.
Braid snake or Jan's cliff racer is a species of snake found in Central Asia.
The common trinket snake is a nonvenomous constrictor species of colubrid snake native to south Central Asia.
The Mandarin rat snake is a species of nonvenomous colubrid snake endemic to Asia. It is closely related to Euprepiophis conspicillata, the Japanese forest rat snake. Mandarin rat snakes are one of the most popular rat snakes found in the pet trade.
Oreocryptophis porphyraceus is a rat snake species, commonly called the black-banded trinket snake, red bamboo snake,, found in mid to upper-level elevations of forested hills in southeastern Asia, ranging from evergreen tropical to dry seasonal forests depending on the subspecies and locality. It is the only member of the genus Oreocryptophis, but it was formerly placed in Elaphe.
Gonyosoma prasinum is a species of colubrid snake found in Asia.
The eastern trinket snake is a species of snake in the family Colubridae. The species is endemic to South Asia.
Gonyosoma oxycephalum, known commonly as the arboreal ratsnake, the red-tailed green rat snake, and the red-tailed racer, is a species of snake in the family Colubridae. The species is endemic to Southeast Asia.
Ptyas mucosa, commonly known as the oriental ratsnake, Indian rat snake, darash or dhaman, is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia. Dhamans are large snakes. Typical mature total length is around 1.5 to 1.95 m though some exceed 2 m. The record length for this species was 3.7 m, second only to their cousin Ptyas carinata among living colubrid snakes. Despite their large size, oriental ratsnakes are usually quite slender with even a specimen of 2 m commonly measuring 4 to 6 cm only around in diameter. Furthermore, the average weight of ratsnakes caught in Java was around 877 to 940 g, though larger males of over 2.3 m may easily weigh over 2.5 kg (5.5 lb). Their color varies from pale browns in dry regions to nearly black in moist forest areas. Rat snakes are diurnal, semi-arboreal, non-venomous, and fast-moving. Rat snakes eat a variety of prey and are frequently found in urban areas where rodents thrive.
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo snakes.
Coelognathus is a genus of seven rat snakes from South and Southeast Asia that were formerly assigned to the genus Elaphe. Based on morphological evidence and protein similarities, in 2001, Helfenberger revalidated the name Coelognathus that had originally been proposed by Leopold Fitzinger in 1843. The distinction between Coelognathus and Elaphe was further supported by mitochondrial DNA sequence and additional morphological evidence in 2005.
The twin-barred tree snake is a species of snake found in Southeast Asia. It is also called the banded flying snake. It can glide, as with all species of its genus Chrysopelea, by stretching the body into a flattened strip using its ribs. It is mostly found in moist forests and can cover a horizontal distance of about 100 metres in a glide from the top of a tree. It is an oviparous snake.
Coelognathus flavolineatus, the black copper rat snake or yellow striped snake, is a species of colubrid snake found in Southeast Asia. This species was previously recognized in the genus Elaphe.
Euprepiophis perlaceus, also known as Sichuan rat snake or pearl-banded rat snake, is a species of snake in the family Colubridae snake. It is endemic to western Sichuan Province in China. This snake is designated as Endangered by the IUCN Red List. It is found in the Palearctic.
