Both sexes may use their claws to grip the seafloor as they crawl along underwater. Females may also use their claw as they move on beaches. So while sea turtles do use that claw on their front flipper, Dr. Innis also says that sea turtles also do just fine with no nails. For example, sometimes rescued sea turtles turn up with lots of injuries to their face and flippers.
Those patients recover and make do just fine without those nails—huzzah! Most turtles you would come across are freshwater turtles. Freshwater turtles are generally smaller as compared to other turtles. These turtles are generally aquatic or semi-aquatic and spend most of their time in aquatic environments. Apart from box turtles , which spend less time in the water, all other freshwater turtles spend most of their time in water.
Some such as the Japanese pond turtle can spend months at the bottom of a pond or stream. Examples include snapping turtles, cooters, softshell turtles, sliders, box turtles, wood turtles, and map turtles. These can be found in the sea. They are generally large turtles and are generally purely aquatic. They do come to shore to lay eggs. The most telling feature of this type of turtle is its flippers. Instead of feet, sea turtles have flippers.
Examples include leatherback sea turtles, hawksbill sea turtles, and Atlantic ridley sea turtles. These are exclusively found on land. They have high domes, and their shells are generally heavier and less streamlined.
Identify a tortoise by inspecting the feet. They have short, elephantine legs. When land tortoises move, they walk on their toes. Examples include Greek tortoises, Russian tortoises, Indian Star tortoises, and red-footed tortoises. If you have pet turtles, knowing how to identify a turtle is a must. To best identify the turtle species , strictly follow the steps.
The Cumberland slider has an olive-green to brownish carapace with yellow markings. The yellow-bellied slider has a solid yellow plastron. Thus the name yellow-bellied. Red-eared sliders have a red patch behind their eyes. This looks like a red ear. The northern red-bellied cooter Pseudemys rubriventris has a red or reddish-orange plastron.
The edges of the plastron are usually redder forming a red margin around the plastron. The carapace is brown or black with traversal yellow and orange stripes. It also has about 11 or more stripes on the head and necks. The plastron is reddish-orange to yellow with dark lines between the scutes that fade with age. The coastal plain cooter Pseudemys concinna floridana has 10 or fewer stripes on the head and neck.
The plastron of this species is yellow and lacks any patterns. If the sea turtle has no scutes, then it is a leatherback sea turtle Dermochelys coriacea. If the sea turtle has five pleural scutes and a squarish first vertebral scute with pores in its bridge scutes and four or five inframarginal scutes, it is the Atlantic ridley sea turtle Lepidochelys kempii.
If the sea turtle has four pleural scutes and a triangular first vertebral scute with two pairs of prefrontal scales on its head then it is the critically endangered hawksbill sea turtle Eretmochelys imbricata. If the sea turtle has five pleural scutes and a squarish first vertebral scute with a large ovoid plate on its dorsum, and four or three inframarginal scutes on it bridge, then its a loggerhead sea turtle Caretta caretta.
Land tortoises unlike their aquatic cousins turtles prefer to dwell on land. They are poor swimmers and have heavier shells.
