Hastings' Dictionary of the Bible [1]

CROCODILE . (1) livyâthân ,   Psalms 74:14 ,   Isaiah 27:1 ,   Job 41:1 f. The last reference is almost certainly to the crocodile, which is adopted in RVm [Note: Revised Version margin.] . See Leviathan. (2) hayyath qâneh , ‘the wild beast of the reeds,’   Psalms 68:30 RV [Note: Revised Version.] , is thought by many to be the crocodile or the hippopotamus as symbolizing Egypt. (3) In   Jeremiah 14:6 tannîm is in RVm [Note: Revised Version margin.] ‘crocodiles.’ See Dragon. For ‘land crocodile’ see Lizard. The crocodile probably still exists in the Nahr ez-Zerka , S. of Mount Carmel, called by Pliny the Crocodile River. It is supposed to have been brought there by some Egyptian settlers. A dead crocodile was brought from there to the late Rev. J. Zeller of Nazareth. Herr Schumacher reports that he saw one there, and quite recently a number of crocodile’s eggs were brought from this river and sold in Jerusalem. A stuffed specimen is in the PEF [Note: EF Palestine Exploration Fund.] museum, London.

Webster's Dictionary [2]

(1): (n.) A fallacious dilemma, mythically supposed to have been first used by a crocodile.

(2): (n.) A large reptile of the genus Crocodilus, of several species. They grow to the length of sixteen or eighteen feet, and inhabit the large rivers of Africa, Asia, and America. The eggs, laid in the sand, are hatched by the sun's heat. The best known species is that of the Nile (C. vulgaris, or C. Niloticus). The Florida crocodile (C. Americanus) is much less common than the alligator and has longer jaws. The name is also sometimes applied to the species of other related genera, as the gavial and the alligator.

Kitto's Popular Cyclopedia of Biblial Literature [3]

We shall in this place confine ourselves to some notice of crocodiles strictly so called, and shall point out some leading characters in the animal coinciding with allusions to it in the Scriptures, which could not be properly noticed elsewhere.
