Adult generally weigh 45 kg with a body length of 65 cm. Adult Kemp's ridleys' shells are broad and light gray-olive in color. They are off-white to light yellow underneath which is called their plastron.

Juvenile turtles have gray-black carapaces top shells and plastrons. Hatchlings have lighter gray-olive carapaces and plastrons. There are 2 pairs of prefrontal scales on the head, 5 vertebral scutes back plates5 pairs of costal scutes belly plates and 12 pairs of marginals rimming plates on their carapace.

Four scutes perforated by a pore are found on each bridge joining the plastron to the carapace. The pore is the opening of their Rathke's gland which secretes a substance of unknown function.

Males resemble the females in size and coloration. Secondary sexual characteristics of male sea turtles include a longer tail, more distal vent, recurved claws and, during breeding, a softened mid-plastron.

Although sea turtles cannot withdraw their heads into their shells, the adults are protected from predators by their shells, large size and thick scaly skin on their heads and necks. Sea turtles spend almost all their lives submerged but must breathe air for the oxygen needed to meet the demands of vigorous activity.

With a single explosive exhalation and rapid inhalation, sea turtles can quickly replace the air in their lungs. Their lungs are adapted to permit a rapid exchange of oxygen and to prevent gasses from being trapped during deep dives.

The blood of sea turtles can deliver oxygen efficiently to body tissues even at the pressures encountered during diving. During routine activity green and loggerhead sea turtles dive for about 4 to 5 minutes and surface to breathe for 1 to 3 seconds.

A female loggerhead tracked at sea made up to dives every 12 hours. Sea turtles can rest or sleep underwater for several hours at a time but submergence time is much shorter while diving for food or to escape predators.

Breath-holding ability is affected by activity and stress, which is why turtles drown in shrimp trawls and other fishing gear within a relatively short time. Because sea turtles are difficult to study in the open ocean, scientists are just beginning to learn about the life history of sea turtles.

Today, radio transmitters, attached to nesting turtles, help track the sea creatures on their travels and provide valuable information.
