Turtles are an order of reptiles known as the Testudines, characterized by a carapace developed mainly from their ribs. Modern tortoises are divided into two major groups, the side-necked tortoises and the hidden-necked tortoises which differ in the way the head retracts. There are 360 species of living and recently extinct turtles, including tortoises and tortoises. They are found on most continents, some islands, and much of the ocean. Like other reptiles, birds, and mammals, they breathe air and do not lay eggs underwater, although many species live in or around water. Genetic evidence generally places them in close relation to crocodilians and birds.
Turtle shells are made mostly of bone; the upper part is the domed carapace, while the lower part is the flatter plastron or ventral plate. Its outer surface is covered with scales made of keratin, the material of hair, horns and claws. Carapace bones grow from ribs that grow laterally and turn into broad, flat plates that come together to cover the body. Turtles are ectotherms or “cold-blooded”, which means that their internal temperature varies with their direct environment. They are generally opportunistic omnivores and feed mainly on plants and animals with limited movements. Many turtles migrate short distances seasonally. Sea turtles are the only reptiles that migrate long distances to lay their eggs on a favored beach.
Turtles have appeared in myths and folk tales around the world. Some terrestrial and freshwater species are widely kept as pets. Turtles have been hunted for their meat, for use in traditional medicine, and for their shells. Sea turtles are often accidentally killed as bycatch in fishing nets. Around the world, turtle habitats are being destroyed. Due to these pressures, many species are threatened with extinction.
