genus of reptiles

Naja is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Various species occur throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are often called "cobras", such as the king cobra and the rinkhals, but they are not "true cobras", in that they do not belong to the genus Naja.

Titanoboa (; ) is a genus of extinct giant boid snake (being the biological family of all boas and anacondas) that lived during the middle and late Paleocene epoch. Titanoboa was first discovered in the early 2000s by members of the Smithsonian Tropical Research Institute, which–along with students from the University of Florida–recovered 186 fossils of Titanoboa from the Cerrejón coal mines in the La Guajira department of northeastern Colombia. It was named and described in 2009 as Titanoboa cerrejonensis, and lauded as the largest snake ever found at that time. The original type

Crotalus is a genus of pit vipers, commonly known as rattlesnakes or rattlers, in the family Viperidae. The genus is found only in the Americas from southern Canada to northern Argentina. The generic name Crotalus is derived from the Greek word krótalοn, which means "rattle" or "castanet", and refers to the rattle on the end of the tail, which makes this group (genera Crotalus and Sistrurus) so distinctive. As of July 2023, 44 to 53 species are recognized as valid.

Vipera (; commonly known as the palaearctic vipers and Eurasian vipers) is a genus of snakes in the subfamily Viperinae of the family Viperidae. The genus has a very wide range, being found from North Africa to just within the Arctic Circle, and from Great Britain to Pacific Asia. The Latin name vīpera is possibly derived from the Latin words vivus and pario, meaning "alive" and "bear" or "bring forth"; likely a reference to the fact that most vipers bear live young. 21 species are recognized as being valid. Like all other vipers, the members of this genus are venomous.

Natrix is a genus of Old World snakes found mainly across Eurasia (although the range of Natrix tessellata extends into Egypt and those of N. astreptophora and N. maura into north-west Africa) in the subfamily Natricinae of the family Colubridae. They are commonly called grass snakes and water snakes, but some other snake species also known commonly as "grass snakes" and "water snakes" are not in the genus.

Echis (common names: saw-scaled vipers, carpet vipers) is a genus of vipers found in the dry regions of Africa, the Middle East, India, Sri Lanka and Pakistan. They have a characteristic threat display, rubbing sections of their body together to produce a "sizzling" warning sound. The name Echis is the Latin transliteration of the Greek word for "viper" (ἔχις). Like all vipers, they are venomous. Their common name is "saw-scaled vipers" and they include some of the species responsible for causing the most snakebite cases and deaths in the world. Twelve species are currently recognized.

Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity how

Elaphe is a genus of snakes in the family Colubridae. Elaphe is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere. Elaphe species are medium to large constrictors by nature.

The Cylindrophiidae are a monotypic family of secretive, semifossorial, non-venomous snakes containing the genus Cylindrophis found in southeastern Asia. These are burrowing snakes and most have a banded pattern on the belly. Currently, 14 species are recognized, all with no subspecies. Common names include Asian pipesnakes and Asian cylinder snakes.

Chrysopelea is a genus of snakes, commonly known as flying snakes or gliding snakes, that belong to the family Colubridae. Chrysopelea species are found in Southeast Asia, and are known for their ability to glide between trees. Flying snakes are mildly venomous, though the venom is dangerous only to their small prey. There are five species within the genus.

Bitis is a genus of vipers found in Africa and the southern Arabian Peninsula. It includes the largest and the smallest vipers in the world. Members are known for their characteristic threat displays that involve inflating and deflating their bodies while hissing and puffing loudly. The type species for this genus is B. arietans, which is also the most widely distributed viper in Africa. Currently, 18 species are recognized.

Dasypeltis is a genus of snakes, also known commonly as egg-eating snakes or egg-eaters, in the subfamily Colubrinae of the family Colubridae. The genus is one of only two taxonomic groups of snakes known to have adapted to feed exclusively on eggs (the other being the genus Elachistodon). Dasypeltis are non-venomous and found throughout the continent of Africa, primarily in forested or wooded habitats that are also home to numerous species of birds.

Coronella is a genus of harmless snakes in the family Colubridae. The genus is endemic to Europe, North Africa and West Asia. Two species are currently recognized as being valid.

Acanthophis is a genus of elapid snakes commonly referred to as 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 and resemblance to many species of vipers, they belong to a different family, the Elapidae.

genus of reptiles

Atheris is a genus of vipers known as bush vipers. They are found only in tropical subsaharan Africa (excluding southern Africa) and many species have isolated and fragmented distributions due to their confinement to rain forests. Like all other vipers, they are venomous. In an example of convergent evolution, they show many similarities to the arboreal pit vipers of Asia and South America. Seventeen species are currently recognized.

Agkistrodon is a genus of pit vipers commonly known as American moccasins. The genus is endemic to North America, ranging from the northeastern United States to northern Costa Rica. Eight species are recognized as being valid, all of them monotypic and closely related. Common names include: cottonmouths, copperheads, and cantils.

genus of reptiles

Ahaetulla, commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. They are considered by some scientists to be mildly venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglyphous, meaning their enlarged teeth or fangs, intended to aid in venom delivery, are located in the back of the upper jaw, instead of in the front as they are in vipers or cobras. As colubrids, Ahaetulla do not possess a true venom gland or a sophisticated venom delivery system. The Duvernoy's gland of this genus

Hydrophis is a genus of sea snakes, venomous snakes in the subfamily Hydrophiinae of the family Elapidae. Species in the genus Hydrophis are typically found in Indo-Australian and Southeast Asian waters. Currently, around 36 species are recognized as being valid.

Heterodon is a genus of harmless colubrid snakes endemic to North America. They are stout with upturned snouts and are perhaps best known for their characteristic threat displays. Three species are currently recognized. Members of the genus are commonly known as hognose snakes, hog-nosed snakes, North American hog-nosed snakes, and colloquially puff adders (though they should not be confused with the venomous African vipers of the genus Bitis).

Macrovipera, known as the large Palearctic vipers, is a genus of vipers that inhabit the semideserts and steppes of North Africa, the Near and Middle East, and the Milos Archipelago in the Aegean Sea. Like all other vipers, they are venomous. These snakes are responsible for a number of bites in Africa and Western Asia every year. They have a reputation for being ill-tempered and can inject a lot of venom, which is why they should be considered as very dangerous. Two species are currently recognized.

Daboia is a genus of vipers.

Causus is a genus of vipers found only in sub-Saharan Africa. It is a group considered to be among the most primitive members of the family Viperidae based on head scalation, oviparity, venom apparatus, and because they have round pupils. However, this is contradicted by recent molecular studies. Seven species are currently recognized as being valid. They are commonly known as night adders. Like all other vipers, they are venomous.

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 consi
