Loggerhead sea turtle assays (immune study dealing with radiolabeling). Lachrymal glands located behind each eye allow the loggerhead to maintain osmotic balance by eliminating the excess salt obtained from ingesting ocean water. On land, the excretion of excess salt gives the false impression that the turtle is crying. The loggerhead sea turtle has a cosmopolitan distribution, nesting over the broadest geographical range of any sea turtle.

They primarily eat insects, but also consume arachnids, reptiles, amphibians, rodents, bats and small birds. The size of prey ranges from 0.001 g insects to 25 g
