Say what the tortoise looks like in a few words.

The tortoise is like a hammer, with a thin neck and a round head.

The tortoise has a special shell from which the head, tail and limbs can extend and retract. The whole body is box-shaped and can be divided into three parts: head and neck, trunk, limbs and tail. The back of the head is slightly triangular, black or brown-black, the mouth is located in the front of the head, the front of the head is smooth, and the back is fine and scaly. The upper and lower jaws are toothless, and the edge of the jaw is covered with a tough fishy sheath called beak. Nose is located in front of the kiss. Smell and touch are developed.

The tortoise is box-shaped, and the whole body is wrapped in a box-shaped turtle shell. Tortoise shell is obviously divided into two parts: the carapace and the abdominal carapace, which are connected by a nail bridge. The carapace and carapace are composed of two layers, the outer layer is the cutin shield from epidermis and the inner layer is the bone plate from dermis. The shield slot between the shields does not overlap with the bone seam of the bone plate, so the turtle shell is extremely strong.
