American climbing snakes
|American climbing snakes|
Corn snake ( Pantherophis guttatis )
|Fitzinger , 1843|
Description and behavior
The species of the genus Pantherophis are characterized by a slender body with only a slightly detached head. They reach body lengths between 100 cm and 250 cm. Many species are pronounced cultural followers and are therefore often found in the vicinity of human settlements, in addition, some species are very active climbers and can sometimes also be found in trees, which gave the genus its common German name. All species of the genus reproduce oviparously and do not practice brood care.
distribution and habitat
The distribution area of the genus extends over large parts of the USA and Mexico . The habitats inhabited by the different species range from wet deciduous and coniferous forests over the prairie to rocky heights at over 2500 m above sea level.
In 2002, the previously valid genus of climbing snakes ( Elaphe ) was split into several genera after detailed scientific research. The genus Pantherophis , already described in 1843, was reintroduced for this purpose. This change is widely accepted.
In 2008 there was another change in the classifications by Collins & Taggart. The peanuts were placed in the genus Scotophis and the fox snakes in the new genus Mintonius . The genus Pantherophis would only consist of the three corn snake species Pantherophis guttatus , Pantherophis emoryi and Pantherophis slowinksii . This change is controversial, however, as it would obscure the relationship to the earth snakes and the fox snakes. Pyron et al. do not adopt this classification. Accordingly, the species of peanuts and chestnuts continue to be assigned to the genus Pantherophis :
Group of corn snakes
- Prairie corn snake ( Pantherophis emoryi )
- Corn snake ( Pantherophis guttatus )
- Slowinski's corn snake ( Pantherophis slowinskii )
Group of peanuts
- Pantherophis alleghaniensis
- Baird's climbing snake ( Pantherophis bairdi )
- Ground snake ( Pantherophis obsoletus )
- Gray pilot snake ( Pantherophis spiloides )
Group of Fox Snakes
The closest related genus of Pantherophis is Pituophis .
