It doesn't say that.

The bible does mention a great beast. This actually fits with what know about how big they used to be.
)))))In the Bible, in Job 40:15–24, God describes to Job (who lived after the Flood) a great beast with which Job was familiar. This great animal, called “behemoth,” is described as “the chief of the ways of God,” perhaps the biggest land animal God had created. Impressively, he moved his tail like a cedar tree! Although some Bible commentaries say this may have been an elephant or hippopotamus, the description actually fits that of a dinosaur like Brachiosaurus. Elephants and hippos certainly do not have tails like cedar trees!((((((
