Sea turtle is the name for several species of large marine turtles, a reptile of the order Chelonia, with strong, beaked, toothless jaws and, usually, an armorlike shell. The shell normally consists of bony plates overlaid with horny shields and is
found in tropical and subtropical oceans. These turtles are modified for life in the ocean by having flipperlike forelimbs without toes and lightweight shells. Their heads are too large to be withdrawn into the shell. They spend most of their lives in the water, but come ashore to lay their eggs. All sea turtle species are declining in numbers, owing in large part to the destruction of the eggs, which are widely used as food in tropical regions. Sea turtle meat is also eaten, and there is a market for turtle oil, hide, and shell. In a few places, such as Sarawak, harvesting of eggs is regulated by law to insure propagation of the species. The size of sea turtles has also decreased, owing to the hunting of large specimens. Nearly all species have a circumglobal distribution although there are differences between the Atlantic and the Pacific populations
Any of some 50 species (family Hydrophiidae) of venomous, marine snakes with an oarlike tail and flattened body. Most are found along coasts and in estuaries of Australia and Asia, sometimes basking on the surface in a large group, though the yellow-bellied, or pelagic, sea snake ranges throughout the Pacific. The nostrils, usually on top of the snout, have valvelike closings. The body of several species is much thicker than the head and neck. Most species are 1–1.2 m long.
