About what the E.D.O.O. says.

Its rubbish.

There are very few animals that float on the sea, and none with brains. Only some jellyfish do this. Yama is not a jellfish - it has eyes. Any creature on the surface of the sea would be so vunerable from attack from below, and lack of food, that it would go extinct very fast.

I have always thought that yama floats on fart gas, predominatly hydogen, collected in its very enlarged large intestine. It is likely that the bones were discarded as they were too heavy, and any bones would be largly vestigial.
