The U.S. state of Alabama is home to 93 indigenous reptile species, not including subspecies. Indigenous species include one species of crocodilian, 12 lizard species, 49 snake species, and 31 turtle species. Three native species have possibly been extirpated from the state. These include the eastern indigo snake, southern hognose snake and the mimic glass lizard. [1] [2]
There are four known introduced reptile species, all lizards. [3] They include the Indo-Pacific gecko, brown anole, Texas horned lizard, and Mediterranean house gecko. [4]
Human predation and habitat destruction has placed several reptile species and subspecies at risk of extirpation or extinction. The Alabama Department of Conservation and Natural Resources lists the conservation status of each species within the state with a rank of lowest, low, moderate, high, and highest concern.

The slender glass lizard is a legless lizard in the glass lizard subfamily (Anguinae). The species is endemic to the United States. Two subspecies are recognized. The lizard was originally believed to be a subspecies of the eastern glass lizard. Their name comes from their easily broken tail which they can break off themselves without ever being touched. It is difficult to find a specimen with an undamaged tail. The lizard eats a variety of insects and small animals, including smaller lizards. Snakes and other animals are known to prey on the species. Humans have a part in destroying their environment and killing their food supply with insecticides. The lizard is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though it is vulnerable in Iowa and endangered in Wisconsin. It is important to note that the streamlined, legless species is often confused with snakes. Glass Lizards, however, differ from snakes as they possess a moveable eyelid, which is absent in snakes. Another way to distinguish glass lizards from snakes is the presence of an external ear opening, which are absent in snakes.
The fauna of Barbados comprises all the animal species inhabiting the island of Barbados and its surrounding waters. Barbados has less biodiversity than the other Antilles. Human activities are responsible for the change in the composition of the fauna, in particular, the replacement of native species. Species that are able to adapt to human presence have survived.
Heterodon simus, commonly known as the southern hog-nosed snake, is a harmless snake species endemic to the southeastern United States. No subspecies are currently recognized.

The Chennai Snake Park, officially the Chennai Snake Park Trust, is a not-for-profit NGO constituted in 1972 by herpetologist Romulus Whitaker and is India's first reptile park. Also known as the Guindy Snake Park, it is located next to the Children's Park in the Guindy National Park campus. Located on the former home of the Madras Crocodile Bank Trust, the park is home to a wide range of snakes such as adders, pythons, vipers, cobras and other reptiles. The park gained statutory recognition as a medium zoo from the Central Zoo Authority in 1995.
Lampropeltis triangulum syspila, commonly known as the red milk snake or red milksnake, is a subspecies of the milk snake (Lampropeltis triangulum). The nonvenomous, colubrid snake is indigenous to the central United States.
Nerodia clarkii clarkii, the Gulf salt marsh snake, is a subspecies of N. clarkii that is indigenous to the south-eastern United States. It is a nonvenomous, colubrid snake that inhabits coastal salt marshes and brackish estuaries along the coast of the Gulf of Mexico from Florida to Texas.
