It is the Lacerta crocodilus of Linnæus, the Crocodilus vulgaris of Cuvier. Its jaws project moderately; there are six cervical plates; the dorsal shields or scutcheons are quadrangular and surrounded by six rows of slightly elevated carinæ. The hinder feet are palmated, their posterior border with a a festooned crest. It is about 25 feet long.
At least four varieties of it exist. It was held sacred among the ancient Egyptians. The Nile was and is its best known habitat.
The leviathan of Job is almost certainly the crocodile, but in other parts of the Scripture different animals are designated by the same word. C.
