The Book of Jonah does not mention Leviathan. In any case, scholars familiar with the biblical references to Leviathan and with similar Near Eastern creation myths, say that Leviathan was a mythical chaos monster.
Additional Answer:
No, Leviathan is not mentioned in Jonah. Perhaps you are confusing this with Jonah being in the belly of the fish God prepared to swallow him where he remained 3 days and 3 nights (Jonah 1:17).
Leviathan is only mentioned in Job 41; Psalms 74:14; 104:26.
JonahJonah 1:17 -Now the Lord had prepared a great fish to swallow Jonah. And Jonah was in the belly of the fish three days and three nights.
Jonah was told by God to go to a place called Ninevah where the people were terrible. God wanted Jonah to speak to them and help them see that they needed to change their ways. But, Jonah decided not to go so God had a giant fish, sometimes said to be a whale, swallow Jonah to teach him a lesson. Don't worry, Jonah lived.
Originally it was the leviathan, an imaginary, giant beast of the sea.(Really giant, it covered the entire sea bed.) Since the story of Jonah is recorded in the scripture, the scripture has the answer for this.17Now the LORD had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights. A fish is not a whale, in terms of modern scientific classification, since a whale is a mammal. However it appears unclear what the actual Hebrew word used could be referring to. Some have suggested it was a large shark. The Leviathan is a different creature, with a different Hebrew word used, and so it was not a Leviathan. In any case, it was not any kind of mythological creature, but a real existent one.
When the bible talks about Jonah and the big fish, it is in the book Jonah in the old testament.
Jonah comes before Micah, And the book of Jonah is also titled Jonah.
