Answer 1

Some animals can get sunburns, the sea turtle for example.  However the hard shelled creatures, such as crabs and mollusks, are pretty well protected from sunburn.  Soft bodied animals, such as sea squirts, have another type of protection.  Their pigmentation.  Sea squirts, for example, produce a natural sunscreen, tridentol, that's more effective than commercial sunscreen.
