What do sea otters use to crack open hard-shelled prey?
Answer
Rocks
A sea otter keeps a favourite rock in a pouch of loose skin under its forearm, then floats on its back and hammers clams and mussels open against it. Otters are among the few animals that carry a tool around rather than picking one up as needed.
