Pogona

Pogona is a genus of reptiles containing eight lizard species, which are often known by the common name bearded dragons. The name "bearded dragon" refers to the "beard" of the lizard, the underside of the throat which turns black if they are stressed or see a potential rival. They are adept climbers, spending time on branches and in bushes and near human habitation. Pogona species bask on rocks and exposed branches in the mornings and afternoons. They are found throughout much of Australia in a wide range of habitats such as deserts, shrublands and Eucalyptus woodlands.[2]
Several species of this genus, especially the central bearded dragon, are often kept as pets or exhibited in zoos due to their hardy nature and easy care in comparison to other exotic reptiles. Some are incredibly smart and good natured.

Lampropeltis triangulum

Lampropeltis triangulum, commonly known as a milk snake or milksnake, (French: Couleuvre tachetée; Spanish: Culebra-real coralillo)[1] is a species of king snake. There are 24 subspecies of milk snakes. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as the subspecies L. t. elapsoides, but is now recognized as a distinct species.[1] The subspecies have strikingly different appearances, and many of them have their own common names. Some authorities suggest that this species may be split into several separate species.[1] They are not venomous or otherwise dangerous to humans.


Geographic range 

They are distributed from southeastern Canada through most of the continental United States to Central America, down to western Ecuador and northern Venezuela of northern South America.

Chrysemys picta sub. marginata

The painted turtle (Chrysemys picta) is the most widespread native turtle of North America. It lives in slow-moving fresh waters, from southern Canada to Louisiana and northern Mexico, and from the Atlantic to the Pacific. The turtle is the only species of the genusChrysemys, which is part of the pond turtle family Emydidae. Fossils show that the painted turtle existed 15 million years ago. Four regionally based subspecies (the eastern, midland, southern, and western) evolved during the last ice age.

The adult painted turtle female is 10–25 cm (4–10 in) long; the male is smaller. The turtle's top shell is dark and smooth, without a ridge. Its skin is olive to black with red, orange, or yellow stripes on its extremities. The subspecies can be distinguished by their shells: the eastern has straight-aligned top shell segments; the midland has a large gray mark on the bottom shell; the southern has a red line on the top shell; the western has a red pattern on the bottom shell.

Emydoidea blandingii

Blanding's turtle (Emys blandingii or Emydoidea blandingii )[1][3] is a semi-aquatic turtle of the family Emydidae. This North American turtle is considered to be an endangered species throughout much of its range



Taxonomy 

There are differences of opinion as to the genus for this species; both Emys and Emydoidea occur in published sources in 2009, 2010, and 2011.

Chelydra serpentina

The common snapping turtle (Chelydra serpentina) is a large freshwater turtle of the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. This species and the larger alligator snapping turtle are the only two species in this family found in North America (though the common snapping turtle, as its name implies, is much more widespread).[2]
