Cryptocleidus is a friend of long Amao reptiles Plesiosaurus (the meaning of the ribbon lizard) of the necks in the Mesozoic. Ichthyosaurus does not resemble fish clearly, but they adapt themselves to the survival in the sea well still. It has a comparatively short tail and a long neck. The body is wide and tightened very much, and strong ribs form a line thickly, and it is good, and the stomach ribs which developed line up in the abdomen. The limbs possess the flipper which developed well very greatly, and it doubt that this was main promotion means, and there is not it. It does not row this flipper like the oar of the boat in front and back, and it becomes clear that it was moved to flap like the wing of the penguin and the flipper of the tortoise up and down. It had the comparatively small brain that possessed a tooth sharp keenly. At first it use the neck like a slingshot surely and it goes to the game and it is very quick and throw a head like an arrow, and it seems that it catch a fish and ate.
