Spilotes pullatus, commonly known as the chicken snake, tropical chicken snake, [3] or yellow rat snake, [3] is a species of large nonvenomous colubrid snake endemic to the Neotropics.
Including the nominotypical subspecies, the following five subspecies are recognized: [3]
It is found in southern Mexico, Central America, northern and central South America, and Trinidad and Tobago in the Caribbean. [3]
Adults may attain a maximum total length of 2.7 m (8.9 ft). [3]
Dorsally, S. pullatus is black with yellow spots which may form crossbands. The tip of the snout is yellow. The head shields may be mostly yellow, or mostly black, or crossbanded with a combination of yellow and black, but the sutures between the shields are always black. Ventrally, it is yellow with irregular black crossbands.
The body is relatively slender and somewhat laterally compressed. The head is distinct from the neck. The eye is moderate in size with a round pupil. There are no suboculars, and the loreal is either very small or absent. There are 6 or 7 upper labials, the 3rd and 4th entering the eye, the last two very large. The dorsal scales are pointed and overlapping.
The dorsal scales are arranged in 16 (or 14) rows at midbody. Ventrals 198-232; anal plate entire; subcaudals 90-120, divided.
It tends to inhabit forested areas, and is often found near water. [3]
It is mainly arboreal, but also terrestrial. [3] It is diurnal and an active forager.
It feeds on a wide variety of prey, including small mammals (such as rodents and bats), [4] birds, lizards, other reptiles, amphibians, and eggs. [4]
Bothrops atrox — also known as the common lancehead, fer-de-lance, barba amarilla and mapepire balsain — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes, as well as the Caribbean island of Trinidad. No subspecies are currently recognized.
The tiger snake is a large and highly venomous snake of southern Australia, including its coastal islands and Tasmania. These snakes are often observed and locally well known by their banding, black and yellow like a tiger, although the species can be highly variable in coloration and patterning. All populations are classified within the genus Notechis (Elapidae). Their diverse characteristics have been classified either as distinct species or by subspecies and regional variation.
Tantilla melanocephala, commonly known as the black-headed snake or neotropical black-headed snake, is a species of small colubrid snake endemic to Central America and South America.
Spilotes sulphureus, commonly known as the yellow-bellied hissing snake or Amazon puffing snake, is a species of snake in the family Colubridae. The species is found in South America, as well as the Caribbean island of Trinidad.
Mastigodryas boddaerti, commonly known as Boddaert's tropical racer, is a species of snake in the family Colubridae. The species is native to tropical South America including Trinidad and Tobago.
Leptophis ahaetulla, commonly known as the lora or parrot snake, is a species of medium-sized slender snake of the family Colubridae. It is endemic to Central America and northern South America.
Atractus trilineatus, commonly known as the three-lined ground snake, is a species of small burrowing snake in the family Colubridae. The species is native to South America.
Pseudoboa neuwiedii, commonly known as the dark-headed red false boa or Neuwied's false boa, is a species of snake in the family Colubridae. The species is endemic to northern South America.

Erythrolamprus aesculapii, also known commonly as the Aesculapian false coral snake, the South American false coral snake, and in Portuguese as bacorá, or falsa-coral, is a species of mildly venomous snake in the family Colubridae. The species is endemic to South America.
Ptyas mucosa, commonly known as the Oriental rat snake, or Indian rat snake, 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.
Uropeltis nitida is a species of nonvenomous shieldtail snake. The species is endemic to southern India. There are no subspecies that are recognized as being valid.
The viperine water snake or viperine snake is a semiaquatic, fish-eating natricine water snake. Despite its common names, it is not a member of the subfamily Viperinae. It was given its common names due to exhibiting a dorsal colour pattern that superficially resembles that of sympatric adder species. In comparison to other Natrix species its head is also somewhat wider and more distinct from the neck. Like most members of the Natricinae it possesses a venom gland on each side of the upper jaw that produces a mild venom that may play a role in swallowing or digestion. The gland is not associated with an enlarged specialized tooth and the venom has to be applied by chewing. The species usually does not bite as a means of defense, and the effect of a bite would be harmless to humans.
The horseshoe whip snake is a species of snake in the family Colubridae. The species is native to southwestern Europe and northern Africa.
The military ground snake is a species of snake in the family Colubridae. The species is endemic to South America.
Dolichophis jugularis, also known commonly as the black whipsnake and the large whip snake, is a species of snake in the family Colubridae. The species is native to West Asia. There are three subspecies.
Spilotes is a genus of snakes in the family Colubridae. The genus is endemic to the New World.
