Loggerhead Turtle

Loggerhead Sea Turtles (Caretta caretta) have a very large and thick head which resembles a log (where the turtle gets its name). This species is very important to the ecosystem for several reasons. For example they as these turtles feed on invertebrates the shells pass through their systems and fall back to the ocean floor then becoming a source of calcium for other animals. They also provide shelter with over 100 species being found living on the shells of Loggerheads.


There can be a huge variety of size when it comes to Loggerhead Turtles. On average these turtles grow to about 3 feet or 1 meter long and weigh in at 250lbs/113kg, but Loggerheads that weigh more than 1000lbs have been found.


These turtles are primarily carnivorous, using their strong jaws to crush conch and crabs. Though they have been known to eat jellyfish, sponges, or even seaweed.
