Behemoth being the beast of the land and Ziz being the beast of the air.
Leviathan has become associated with any large and frightening sea creature in legend, such as the sea serpent or fictional whales (as mentioned in Moby Dick).
- Most people believe that the Leviathan is either a whale, giant squid, shark, hippo, or a crocodile. Some creationists believe it is either a plesiosaur, mosasaur, prehistoric whale (such as Basilosaurus), hadrosaur, Megalodon, T-rex, or Spinosaurus. Some creationists believed the crocodile theory (which was mentioned in the Book of Job_, but most likely say that it is a Sarchosuchus, a giant prehistoric crocodile. It is even notable that the fossil of Sarchosuchus has an unknown part on its jaw, which some believed that it breathes fire, since the Book of Job mentions that the Leviathan can breathe fire.
