The integuments of the aquatic animals are many in num-

ber. Some are covered with a hide and hair, as the sea-calf and hippopotamus, for instance; others again, with a hide only, as the dolphin; others again, with a shell, ^[Note] as the turtle; others, with a coat as hard as a stone, like the oyster and other shell-fish; others, with a crust, such as the cray-fish; others, with a crust and spines, like the sea-urchin; others, with scales, as fishes in general; others, with a rough skin, as the squatina, ^[Note] the skin of which is used for polishing wood and ivory; others, with a soft skin, like the muræna; ^[Note] and others with none at all, like the polypus. ^[Note]
