A characteristic feature is that the body is covered with a shell consisting of a convex dorsal shield (carapace) and a flat abdominal shield (plastron).
Both shields are connected motionlessly by side bridges or loosely by skin.
The basis of the shell is made up of skin ossifications, as well as expanded ribs and spinous processes of the vertebrae.
How do turtles see the world
Turtles have color vision. The turtle is able to distinguish the color of food and select certain pieces, such as carrots, from a mixed diet.
In determining its likes and dislikes in relation to individuals of its species, the turtle uses vision.
How many years do turtles live
In addition, turtles are one of the longest-livers among all animals on earth.
There is evidence that the giant tortoise Aivata lived 250 years.
In captivity, the reptile's lifespan is about 150 years.
Zoologists have found that the aging rate of many species of turtles when kept in captivity is zero.
Moreover, for representatives of some species, the risk of death completely decreases with age.
Previously, we talked about the Spitz dog breed.
