User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5043481-20120914170502

I have a theory regarding the carapaceons shells, that look like skulls.

I think that the 'skull' is not actually a skull, but a part of the crab that has evolved to look like a skull to scare away predators. For example, when Gaoren walks into area 1 of the fortress he does so backwards so that the 'skull' goes first and any monsters in the area think it is an even larger monster and run away.

Clearly they do not come from actual skulls as the skull is many times larger. Also, the jaw is not correct. The carepaceons skulls have a solid Jaw, whereas actual jaws are made of two bone joined at the middle. Under the jaw is soft tissue (feel your face if you don't beleive me.

The only problem is the shogun centear having three different shells. Maybe the gravios shell is the crabs shell and the others are replacements when that shell was broken.
