The leatherback turtles and turtles of the order Turtles and the family Turtles are large or medium-sized sea turtles with paddle-shaped limbs that are found in tropical and subtropical oceans.

Some species of turtles live very long, some reaching more than 300 years. Common types of large tortoises include elephant tortoises, which are 1.5m long and weigh 200kg. They are famous for being able to carry people crawling on them. The green turtle is a favorite exhibition animal. It is actually a golden turtle or a water turtle with green algae on its carapace.

The limbs are thick and suitable for crawling. The legs are short or have paddle-like flippers (turtles). They have a protective bone shell and are covered with horny armor. The shell is divided into upper and lower halves. The upper half is the carapace, and the lower half is the breastplate. The carapace is connected to both sides of the breastplate.
The longest-lived turtle on record was kept for 152 years, and its lifespan was at least 152 years old. According to reports, a South Korean fisherman caught a sea turtle on the coast. It was 1.5m long and weighed 90kg. It had many oysters and moss attached to its carapace. It was estimated to have a lifespan of 700 years.
