Turtles eat all kinds of food, such as fish, cephalopods, crustaceans, mollusks and seaweed. Mainly distributed in the warm waters of the Pacific Ocean, Atlantic Ocean and Indian Ocean; Turtles have the habit of migrating. When the sea water temperature drops, turtles will migrate to the water with higher water temperature to resist the cold.
Extended data:
There are 7 species of sea turtles in the world, 6 of which belong to Tortoise, and leatherback turtle, as the oldest living sea turtle, exists alone in Tortoise. A little comparison will show that the two are quite different.
The tortoise shell has three rows of horny shields, and the adult shell feels a bit like an old nail. Below the shield is a fairly hard shell, which is formed by overgrowth of dermal bones between vertebrae, ribs and ribs. ?
