Loggerhead Sea Turtle

Topics: Sea turtle
Caretta caretta is commonly called the "Loggerhead" sea turtle due to their overly large heads, which are comprised of a horny beak that is significantly thicker than in other sea turtles. This species is the largest hard-shelled turtle in the world. Loggerhead turtles have large heads (when compared to other species of marine turtles) and strong, muscular jaws (which help them crush prey such as crabs and lobsters).
The loggerhead sea turtle is a marine mammal that grows quite large. Adults of this species weigh from 170-500 pounds (77-227 kilograms) and are nearly four feet (1.2 meters) in total length. The upper shell or carapace is widest near the front, just behind the front flippers, and then tapers toward the rear. The carapace is colored reddish-brown with some yellowish touches; underneath, the plastron is creamy yellow. There are five pairs of costal shields or plates on each side of the central row of plates on the carapace. The shell margin of young loggerheads has a somewhat serrated appearance which disappears as the turtle matures. The limbs are paddle-shaped and each bears two claws. As with all sea turtles, the adult male has a long tail, but the tail of the female is short. Scales on the top and sides of the head and top of the flippers are also reddish-brown, but have yellow borders. The neck, shoulders and limb bases are dull brown on top and medium yellow on the sides and bottom. The plastron is also medium yellow. The average adult size is 92 cm straight carapace length; average weight is 115 kg. Hatchlings, on the other hand are dull brown in color. Average size at hatching is 45 mm long; average weight is 20 g. Maturity of the loggerhead sea turtle is reached at between 16-40 years.
The loggerhead sea turtle resides in the euphotic zone, where they are able to receive sufficient amounts of light. Adults and juveniles live in shallow waters of the continental shelves, often in water only a few tens of meters deep. They spend much of their

    Loggerhead turtles have many significant adaptations to their current and past environments. Turtles of the family Cheloniidae have various morphological adaptations for aquatic life. Early turtles lost the capacity for aquatic propulsion by body and tail undulations when they developed a shortened, more rigid body form during the Triassic, as an adaptation for armored resistance to attack by predators.

    If I was writing a report on an endangered species I would choose the sea turtle.
