Terrapene carolina carolina
Vulnerable

The Eastern Box Turtle is a terrestrial member of the American pond turtle family. It is known for its high-domed shell and the ability to completely close its shell, hence the name 'box turtle'. These turtles can live up to 100 years in the wild.

Seasonal Activity

  • Spring: Most active, emerging from hibernation to feed and mate
  • Summer: Active in early morning and evening, seeking shade during hot days
  • Fall: Preparing for hibernation, feeding heavily
  • Winter: Hibernating in burrows up to 2 feet deep in soft soil

Identification

  • High-domed shell with variable patterns of yellow or orange on a brown background
  • Males typically have red or orange eyes, females usually have brown or yellow eyes
  • Hinged plastron (bottom shell) that can completely close

Seasonal Activity

  • Spring: Emerge from hibernation when water temperatures reach about 50°F
  • Summer: Peak activity, frequently seen basking on logs or rocks
  • Fall: Reduced activity, preparing for hibernation
  • Winter: Hibernating underwater, buried in mud at the bottom of ponds or lakes

Identification

  • Smooth, olive to black carapace (top shell) with red markings along the edge
  • Yellow stripes on the head, neck, and limbs
  • Red and black patterns on the plastron (bottom shell)

Red-eared Slider
Red-eared Slider
Trachemys scripta elegans
Least Concern

The Red-eared Slider is one of the most popular pet turtles in the United States and has been introduced to many areas outside its native range. It gets its name from the distinctive red patch behind each eye and its habit of sliding off logs and rocks into the water when startled.

Habitat & Location

Native to the southern United States and northern Mexico, Red-eared Sliders prefer quiet waters with soft bottoms, abundant vegetation, and basking sites, such as ponds, lakes, marshes, and slow-moving rivers.

Seasonal Activity

  • Spring: Becoming active as temperatures warm, mating season begins
  • Summer: Very active, frequently basking and feeding
  • Fall: Reduced activity as temperatures cool
  • Winter: Brumation (reptile hibernation) at the bottom of water bodies

Identification

  • Olive to brown carapace with yellow stripes or patterns
  • Distinctive red patch behind each eye
  • Yellow stripes on the head, neck, and limbs
  • Adults typically 5-12 inches in length

Loggerhead Sea Turtle
Loggerhead Sea Turtle
Caretta caretta
Endangered

The Loggerhead Sea Turtle is named for its exceptionally large head. It's one of the largest hard-shelled turtles in the world and is found in oceans worldwide. These turtles are known for their long migrations between feeding and nesting grounds.

Habitat & Location

Loggerheads inhabit the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean Sea. In the U.S., they nest primarily along the Atlantic coast from Virginia to Florida and in the Gulf of Mexico.

Seasonal Activity

  • Spring: Migration to breeding areas begins
  • Summer: Nesting season (May-August) on beaches in southeastern U.S.
  • Fall: Return to foraging grounds
  • Winter: Remain in warmer waters, sometimes entering a state of reduced activity

Identification

  • Reddish-brown carapace, often covered with barnacles
  • Very large head with powerful jaws
  • Heart-shaped carapace when viewed from above
  • Adults typically 2.5-3.5 feet in length and 200-400 pounds

Green Sea Turtle
Green Sea Turtle
Chelonia mydas
Endangered

The Green Sea Turtle is named for the greenish color of its fat, not its shell. It's the largest hard-shelled sea turtle and the only herbivorous sea turtle, feeding primarily on seagrasses and algae as an adult.

Habitat & Location

Green Sea Turtles are found in tropical and subtropical waters worldwide. In the U.S., they nest primarily in Florida, Hawaii, Puerto Rico, and the U.S. Virgin Islands, with feeding grounds along both the Atlantic and Pacific coasts.

Seasonal Activity

  • Spring: Migration to breeding areas for some populations
  • Summer: Nesting season in the southeastern U.S. (June-September)
  • Fall: Return to foraging grounds
  • Winter: Remain in warmer waters, sometimes entering a state of reduced activity

Identification

  • Smooth, oval-shaped carapace that can be olive, brown, or black
  • Single pair of prefrontal scales (scales between the eyes)
  • Four pairs of lateral scutes (plates) on the carapace
  • Adults typically 3-4 feet in length and 300-400 pounds

Gopher Tortoise
Gopher Tortoise
Gopherus polyphemus
Vulnerable

The Gopher Tortoise is a terrestrial turtle native to the southeastern United States. It's known for digging extensive burrows that provide shelter for hundreds of other animal species, making it a keystone species in its ecosystem.

Habitat & Location

Gopher Tortoises are found in well-drained, sandy soils in longleaf pine savannas, xeric oak hammocks, scrub, and dry prairies throughout Florida, southern Georgia, southern Alabama, and southeastern South Carolina.

Seasonal Activity

  • Spring: Most active, emerging from burrows to feed and mate
  • Summer: Active in early morning and late afternoon, avoiding midday heat
  • Fall: Preparing for winter, feeding heavily
  • Winter: Less active but not truly hibernating in the southern parts of range

Identification

  • Brown to grayish-brown, unkeeled carapace
  • Flattened forelimbs adapted for digging
  • Short, elephantine hind limbs
  • Adults typically 9-15 inches in length

The Common Snapping Turtle is a large freshwater turtle known for its powerful jaws and aggressive disposition when threatened on land. In water, they are generally docile unless provoked. They are opportunistic omnivores and important scavengers in aquatic ecosystems.

Habitat & Location

Snapping Turtles inhabit almost any type of freshwater habitat throughout the eastern two-thirds of the United States and southern Canada, including lakes, ponds, rivers, and marshes, preferring slow-moving water with muddy bottoms and abundant vegetation.

Seasonal Activity

  • Spring: Becoming active as waters warm, mating season
  • Summer: Active, females nesting on land (May-June)
  • Fall: Feeding heavily before winter
  • Winter: Hibernating in mud at the bottom of water bodies, sometimes remaining active under ice

Identification

  • Large, rough carapace with three longitudinal ridges that smooth with age
  • Long tail with saw-toothed upper ridge

Leatherback Sea Turtle
Leatherback Sea Turtle
Dermochelys coriacea
Critically Endangered

The Leatherback Sea Turtle is the largest of all living turtles and is the only sea turtle without a hard shell. Instead, it has a leathery carapace composed of a mosaic of small bones. These remarkable reptiles can dive deeper than any other sea turtle and can maintain a body temperature higher than the surrounding water due to their unique adaptations.

Habitat & Location

Leatherbacks have the widest global distribution of any reptile, found in the Atlantic, Pacific, and Indian Oceans. They travel further north than any other sea turtle species. In the U.S., they nest primarily in Florida, Puerto Rico, and the U.S. Virgin Islands.

Seasonal Activity

  • Spring: Migration to breeding areas begins for some populations
  • Summer: Nesting season in the Caribbean and Florida (March-July)
  • Fall: Migration to feeding grounds
  • Winter: Feeding in temperate and even sub-polar waters, following jellyfish blooms

Identification

  • Dark, leathery skin with white or pale spots
  • Seven longitudinal ridges on the carapace
  • No visible scales on head or carapace
  • Extremely long front flippers
  • Adults typically 4-6 feet in length and 500-1500 pounds
