Pituophis insulanus, the Cedros Island gopher snake, is a species of snake of the family Colubridae. [2]
Pituophis is a genus of nonvenomous colubrid snakes, commonly referred to as gopher snakes, pine snakes, and bullsnakes, which are endemic to North America.
Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for the prairie rattlesnake, but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail and by the shape of its head, which is narrower than a rattlesnake's.
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.
The speckled kingsnake is a nonvenomous species of kingsnake. It is endemic to the United States.
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.
The Cape gopher snake or Baja gopher snake is a species of nonvenomous colubrid snake endemic to extreme southern Baja California Sur, Mexico. They have become increasingly popular companions for people interested in the exotic pet trade, due to their extreme color variations and relatively docile behavior. It was previously considered to be a subspecies of Pituophis catenifer. There has been controversy whether the Baja Gopher Snake is a lower classification of the Cape Gopher Snake. Some say the Baja Gopher Snake should be in a separate sub-species of Pituophis Vertebralis Bimaris, while Cape Gopher Snakes should remain Pituophis Vertebralis Vertebralis. Many people mistake the two as the same sub species and have cased some cross-breeding between the two. In captivity the bloodlines are nearly all related and breeding has become especially difficult in terms of keeping the bloodlines alive.
Pituophis melanoleucus, commonly known as the eastern pine snake, is a species of nonvenomous snake in the family Colubridae. The species is endemic to the southeastern United States. Three subspecies are currently recognized as being valid.
Luetkenotyphlus insulanus, the insular caecilian, is a species of caecilian in the family Siphonopidae. It is endemic to the Ilhabela archipelago in Brazil. Its natural habitat is subtropical forest where it lives in the soil.
The Louisiana pine snake is a species of large, non-venomous, constrictor in the family Colubridae. This powerful snake is notable because of its large eggs and small clutch sizes. The Louisiana pine snake is indigenous to west-central Louisiana and East Texas, where it relies strongly on Baird's pocket gophers for its burrow system and as a food source. The Louisiana pine snake is rarely seen in the wild, and is considered to be one of the rarest snakes in North America. The demise of the species is due to its low fecundity coupled with the extensive loss of suitable habitat - the longleaf pine savannas in the Gulf coastal plain of the southeastern United States. Management activities are being conducted to promote the species' recovery.
The Pacific gopher snake is a subspecies of large non-venomous colubrid snake native to the western coast of North America.
Olive Griffith Stull (Davis) (February 10, 1905 – June 15, 1969) was an American herpetologist.
Pituophis catenifer deserticola, commonly known by its standardized English name since the 1950s, the Great Basin gophersnake, is a subspecies of nonvenomous colubrid snake ranging in parts of western United States and adjacent southwestern Canada.
The bullsnake is a large, nonvenomous, colubrid snake. It is a subspecies of the gopher snake. The bullsnake is one of the largest/longest snakes of North America and the United States, reaching lengths up to 8 ft.
Platyceps insulanus is a species of snake in the family Colubridae. It is commonly known as the Sarso Island racer.
Lampropeltini is a tribe of colubrid snake endemic to New World. These include the kingsnakes, milk snake, corn snake, gopher snakes, pine snakes, and bullsnakes. At least 51 species have been recognized and the group have been heavily studied for biogeography, morphology, ecology, and phylogenetics. The internal relationships among the genera has been disputed, but generally the most supported placement of the genera are as follows:
Pituophis deppei, commonly known as the Mexican bullsnake and the Mexican pine snake, is a species of nonvenomous colubrid snake endemic to Mexico. There are two recognized subspecies.
Pituophis lineaticollis, commonly known as the Middle American gopher snake or the cincuate bull snake, is a species of nonvenomous snake in the family Colubridae. The species is native to Guatemala and southeastern Mexico. There are two recognized subspecies.
