MARYLAND AT A GLANCE

WILDLIFE

REPTILES

[photo, Eastern Snapping Turtle (Chelydra s. serpentina), Annapolis, Maryland] Although reptiles are classified by four orders, only two are found in Maryland: Scaled Reptiles (squamata), and Shelled Reptiles (testudines). While Shelled Reptiles encompass only turtles, Scaled Reptiles include Snakes (serpentes), and Lizards (lacertilia).

[photo, Eastern Box Turtle (Terrapene c. carolina), Glen Burnie, Maryland] As diverse as their types, Maryland reptiles have many options during the colder months. In addition to hibernation and migration, brumation is a trait unique to reptiles. When reptiles brumate, they remain semi-dormant, going months without food. Still, they remain aware of their surroundings, but only move to secure water.

[photo, Northern Diamondback Terrapin (Malaclemys t. terrapin), Tawes Building, Dept. of Natural Resources, Annapolis, Maryland] Classified as testudines, turtles come in many shapes and sizes. From the Diamondback Terrapin, to the Loggerhead Sea Turtle, Maryland exemplifies this diversity. Known as "sea turtles", members of the Cheloniidae family possess distinct flippers instead of legs, and spend most of their lives underwater. Due to human and animal predations (as well as risks associated with their extensive travels) all species of sea turtles found in Maryland are classified as either endangered, or threatened.

In Maryland, snakes are found mostly in rural and wooded areas. While most are harmless to humans, two species are poisonous: Copperhead, and Timber Rattlesnake.

Whether possessing flippers, feet, or nothing at all, numerous examples of Maryland's reptile populace are on display at the National Aquarium in Baltimore.
