An unknown skull
Did you know that it’s difficult to tell what an animal is by its skeleton alone? If you don’t believe us, Google the skull of a baboon and let us know what you think. This was exactly the problem that one beachgoer was facing when they found a mysterious skull washed up on shore.
After consulting with (self-proclaimed) marine biology experts, the OP discovered that this was the skull of a tuna fish. If you ask us, we think this looks nothing like the delicious fish we eat on sushi rolls. But then again, who are we to argue with internet experts?
