Aelian
Alexandros in his Voyage Round the Red Sea says that he has seen … a species of crab whose shell measured one foot across in all directions, with claws attached and projecting to an enormous length. But nobody has designs upon them, the reason being that they are said to be sacred to Poseidon. And they are consecrated to the god, so that, as offerings to him, they are free from harm and immune from attack. — 17.1
