Does the Bible say anything about chimeras or explains their purpose? Firstly, I'm sorry if it's not the right place to ask this kind of question. I didn't know where else I could ask about it. 
I'm interested in Simon de Myle's painting of the ark. In the middle of the painting, on the right, one may see a chimera/dragon devouring a man. 
I was wondering whether the Bible says anything about chimeras. And if so, how the one of de Myle's painting can be explained. Why a dragon and why devouring a man?
Was it only an artistic vision?
The only strange animals in the Bible are the pre-historic ones mentioned in Job


Leviathan 
Rahab (Also psalm 89)


and 


Behemoth 


Imaginationless bible scholars have equated Behemoth and Leviathan with hippos and crocodiles.  And I answered this question about Rahab a while back, she sounds pretty interesting, probably some sort of dragon!  

and the giants called the Nephilim mentioned in Genesis 6:4, but they'd be dead by then I think - they certainly weren't on the ark.

and the talking donkey of Balaam in Numbers 22, but God made the donkey talk so he's not that strange of a beast. 



A better answer hopefully can comment on Simon De Myle's style, but in the "Here be dragons" style of the map making of the time (1570, there's no reason to think that these creatures weren't talked about or expected to exist in the far reaches of the earth at the time.
