I am posting this question because the questioner did not leave a valid e-mail address. Perhaps he will be able to get the answer here.
Is the leviathan really a beast or just a example of what God was saying to Job?
Nobody knows exactly what leviathan is or was. Apparently it was a beast known to Job. Whether it is one that currently exists or not is uncertain. Some have said it is the crocodile or the hippopotamus. Others believe that if God could create a big fish for the sole purpose of swallowing Jonah he could have created other animals that we only have in the fossil record. Others say, “Who knows. Maybe it is the Loch Ness Monster.”
