The little girl said, "The Bible says Jonah was swallowed by a great fish, and so I believe he was."
"How do you explain the small throat? How could Jonah have gotten down a whale's throat?" asked the teacher.
"I don't know, but I'll ask Jonah when I get to heaven," said the little girl.
"What if Jonah went to hell?" asked the teacher.
"Then," said the little girl, "you can ask him."
I do remember reading somewhere that whale was just assumed that it was a large fish, but never says in the text that it was specifically a whale. Point is, the Bible said it happened, it happened, and these great scientists with all their degrees, and all their scientific equipment can root around underwater for the next 30 years, it still doesn't mean that they will ever come to the correct answer. God covered the earth in water, I don't think there's too much to argue there.
1 Corinthians
19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
20 And again, The Lord knoweth the thoughts of the wise, that they are vain.
