First Jesus is the one who validated the story, as Jonah was in the belly of the fish three days and nights so must the SON of man be three days and nights in the earth (Matthew 12:40). Recently a man testified he was swallowed by a whale and lived to tell about it.
We see a propeller 4 made by 4 whales with two dolphins revealing 4 fins the book of Jonah has in it 4 Chapters with 48 verses in it.
so the 3 4’s add to 12 and Matthew 12:40-48 Jesus asks who are my mother and my brothers in verse 48? Then in verse 49 points to his disciples and proclaims my mother and my brothers. Hail all them full of grace the Lord is with them and not those who try to sneak into heaven some other way.
