Leatherback sea turtle, Dermochelys coriacea (Linnaeus, 1766). These animals were photographed on Trinidad's Matura Beach (east coast of Trinidad). In Trinidad nesting is mostly from March to August. Clutch sizes range from 60-130 eggs, however at least some females deposit eggs three of four times per season. Most of the Trinidad females had shells that were about 1560 mm long. Nest construction and egg deposition can take about 35 minutes. The record sized specimen for this species was reported from Harlech Beach, Gwyneed, Wales in 1988. Leatherbacks feeds on jellyfish and their relatives, and possibly other soft bodied invertebrates. They have an exceptionally long esophagus lined with posterior projecting papillae. The esophagus may store food when the turtle's stomach has reached capacity. Floating plastic debris is a hazard to these giant turtles, because they may ingest plastic bags (and cellophane) that will clog their digestive system. Apparently they cannot distinguish between their jellyfish prey and the plastic.
