Sea turtles (superfamily Chelonioidea), from time to time known as marine turtles, are reptiles of the order Testudines and of the suborder Cryptodira. The seven present species of sea turtles are the inexperienced sea turtle, loggerhead sea turtle, Kemp's ridley sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle, and leatherback sea turtle.

Description

 For every of the seven kinds of sea turtles, girls and adult males are the identical size; there's no sexual dimorphism. In general, sea turtles have a greater fusiform frame plan than their terrestrial or freshwater counterparts. This tapering at each ends reduces extent and method that sea turtles can't, as can different turtles and tortoises, retract their head and limbs into their shells for protection.[6] But the streamlined frame plan reduces friction and drag withinside the water and lets in sea turtles to swim greater without problems and swiftly. The leatherback sea turtle is the biggest sea turtle, measuring 2–three m (6–nine ft) in length, 1–1.five m (three–five ft) in width, and weighing as much as seven-hundred kg (1500 lb). Other sea turtle species are smaller, being frequently 60–a hundred and twenty cm (2–four ft) lengthy and proportionally narrower. The skulls of sea turtles have cheek areas which are enclosed in bone. Although this situation superficially resembles that discovered withinside the earliest regarded fossil reptiles it's miles very probably a greater currently developed trait in sea turtles.

 Taxonomy and evolution

 Sea turtles, together with different turtles and tortoises, are a part of the order Testudines. All species besides the leatherback sea turtle are withinside the own circle of relatives Cheloniidae. The leatherback sea turtle is the handiest extant family member Dermochelyidae. The beginning of sea turtles is going lower back to the Late Jurassic (a hundred and fifty million years ago) with genera which include Plesiochelys, from Europe. In Africa, the primary sea turtle is Angolachelys, from the Turonian of Angola.[11] However, neither of those are associated with extant sea turtles; the oldest consultant of the lineage main to those become Desmatochelys padillai , from the Early Cretaceous. A lineage of unrelated marine testudines, the pleurodire (side-necked) bothremydids, additionally survived properly into the Cenozoic. Other pleurodires also are idea to have lived at sea, which include Araripemys and extinct pelomedusids. Modern sea turtles represent a unmarried radiation that have become wonderful from all different turtles as a minimum a hundred and ten million years ago.Sea turtles' limbs and brains have developed to conform to their diets. Their limbs firstly developed for locomotion, however greater currently developed to useful resource them in feeding. They use their limbs to hold, swipe, and forage their meals. This enables them consume greater efficiently Importance to ecosystems Sea turtles play key roles in habitat types: oceans and seashores/dunes. In the oceans, sea turtles, particularly inexperienced sea turtles, are the various only a few creatures (manatees are another) that consume sea grass. Sea grass desires to be continuously reduce quick to assist it develop throughout the ocean floor. Sea turtle grazing enables keep the fitness of the ocean grass beds. Sea grass beds offer breeding and developmental grounds for severa marine animals. Without them, many marine species people harvest might be lost, as might the decrease stages of the meals chain.
