Loggerheads are one of seven species of sea turtles found in the world. All seven species are threatened or endangered for a variety of reasons. Researchers studying sea turtle biology have learned much about these unique reptiles, but many mysteries still exist.

Loggerhead Turtle
A Loggerhead is released into the ocean

Female sea turtles must leave the ocean to nest on beaches. Loggerhead sea turtle hatchlings spend their first few years in the Sargasso Sea learning how to survive before starting their migrations. From the Sargasso Sea, young loggerheads migrate into shallow coastal waters for foraging purposes. As the water temperature drops in the winter, some sea turtles migrate east to the warm currents of the Gulf Stream, while others prefer to migrate south into warmer waters. Turtles that don’t make it to warmer water can become cold-stunned if the water temperature drops too quickly.

Common name: Loggerhead
Scientific name: Caretta caretta
Status: threatened

Description: primarily reddish-brown incoloration and have large heads with powerful jaws. Males differ from females in having narrower shells and longer/thicker tails.

Size: Between 31 and 45 inches (79-114 cm) long and weighing approximately 170 to 350 pounds (77-159 kg)

Adaptations: both the shell and flippers are built to cut down water resistance (aid in hydrodynamics)

Diet: sea jellies (jellyfish), crabs, lobsters and other crustaceans

Nesting: Female sea turtles mature at about 10 to 15 years of age. It may take several more years before they mate with males in the ocean, and crawl onto sandy beaches to deposit their eggs. Nesting occurs from mid-May through August; eggs incubate for approximately 60 days, resulting in an annual nesting season spanning the interval from mid-May until mid-to-late October. Each clutch consists of approximately 114 eggs the size, shape, and color of ping-pong balls.

Longevity: At least 30 years and up to 50 years or more.
