Thirty species of reptiles have been recorded in the US state of Minnesota, including 17 species of snakes, eleven species of turtle, and three species of lizard. [1] Of those 31 species, two (Blanding's turtle and the wood turtle) have been listed as endangered by the International Union for Conservation of Nature, with another 20 listed as least concern and nine have not been evaluated.
Minnesota does not have an official state reptile. However, the Blanding's turtle was proposed as the reptile of the state in 1998 and 1999. [2]

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.
Blanding's turtle is a semi-aquatic turtle of the family Emydidae. This species is native to central and eastern parts of Canada and the United States. It is considered to be an endangered species throughout much of its range. Blanding's turtle is of interest in longevity research, as it shows little to no common signs of aging and is physically active and capable of reproduction into eight or nine decades of life.
The Madras Crocodile Bank Trust and Centre for Herpetology (MCBT) is a reptile zoo and herpetology research station, located 40 kilometres (25 mi) south of the city of Chennai, in state of Tamil Nadu, India. The centre is both a registered trust and a recognized zoo under the Wildlife (Protection) Act, 1972 and comes under the purview of the Central Zoo Authority, Ministry of Environment and Forests, Government of India. It was established with the aim of saving three Indian endangered species of crocodile—the marsh or mugger crocodile, the saltwater crocodile, and the gharial, which at the time of founding of the trust were all nearing extinction.
The painted turtle is the most widespread native turtle of North America. It lives in slow-moving fresh waters, from southern Canada to northern Mexico, and from the Atlantic to the Pacific. They have been shown to prefer large wetlands with long periods of inundation and emergent vegetation. This turtle is a member of the genus Chrysemys, which is part of the pond turtle family Emydidae. Fossils show that the painted turtle existed 15 million years ago. Three regionally based subspecies evolved during the last ice age. The southern painted turtle is alternately considered the only other species in Chrysemys, or another subspecies of C. picta.
The massasauga is a rattlesnake species found in midwestern North America from southern Ontario to northern Mexico and parts of the United States in between. Like all rattlesnakes, it is a pit viper and is venomous.
North American box turtles are turtles of the genus Terrapene. Although box turtles are superficially similar to tortoises in terrestrial habits and overall appearance, they are actually members of the American pond turtle family (Emydidae). The 12 taxa which are distinguished in the genus are distributed over seven species. They are largely characterized by having a domed shell which is hinged at the bottom, allowing the animal to retract its head and legs and close its shell tightly to protect itself from predators.
Pantherophis vulpinus, commonly known as the foxsnake or the eastern fox snake, is a species of nonvenomous rat snake in the family Colubridae. The species is native to North America.
The common box turtle is a species of box turtle with six existing subspecies. It is found throughout the Eastern United States and Mexico. The box turtle has a distinctive hinged lowered shell that allows it to completely enclose itself. Its upper jaw is long and curved.
The three-toed box turtle is a species within the genus of hinge-shelled turtles commonly referred to as box turtles. This species is native to the south-central part of the United States and is the official reptile of the state of Missouri.
The plains garter snake is a species of garter snake native to most of the central United States as far north as Canada and as far south as Texas. It has a distinctive orange or yellow stripe from its head to tail, and the rest of its body is mainly a gray-green color. The snake is commonly found living near water sources such as streams and ponds, but can also be found in urban areas and vacant lots. Although the IUCN lists the species as "Least Concern", some states have given it their own special status. This species is mildly venomous, although the venom is not toxic to humans.
The yellow mud turtle, also commonly known as the yellow-necked mud turtle, is a species of mud turtle in the family Kinosternidae. The species is endemic to the Central United States and Mexico.
The Malayan softshell turtle is a species of softshell turtle in the family Trionychidae. It is monotypic in its genus.
The northern map turtle, also known as the common map turtle, is an aquatic turtle in the family Emydidae. It is endemic to North America.
The Ouachita map turtle is a species of turtle belonging to the family Emydidae.
The abundant painted turtle species is captured from the wild, primarily for pet use. Commercial harvesting is a small-scale industry that faces growing restrictions, but still occurs, in some cases unconstrained. Recreational harvesting, is generally allowed in much of the species range. However, it is prohibited in areas where the species is threatened and in a few non-threatened locations. Generally, turtles are captured by live trapping. Floating basking-style traps work better than staked, baited hoop-style traps, but both are employed. Because the turtles are long-lived, with lower replacement rates than typical game, concerns exist for over-harvesting. In this, they are similar to species such as snapping turtles, with late-aged sexual maturity, albeit not to the same extent.
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.
Missouri is home to a diversity of both flora and fauna. There is a large amount of fresh water present due to the Mississippi River, Missouri River, and Lake of the Ozarks, with numerous smaller tributary rivers, streams, and lakes. North of the Missouri River, the state is primarily rolling hills of the Great Plains, whereas south of the Missouri River, the state is dominated by the Oak-Hickory Central U.S. hardwood forest.
