Why starfish have such a heightened sense of smell.

Chemoreceptors on the starfish's skin can detect the faintest smell of its prey (clams), and even determine the direction from which it is coming.Because starfish lack teeth, they must convert their food to liquid form before they can ingest it. Among the other prey items this bottom-dwelling predator eats are sea urchins, other starfish, small fish, sponges, and carrion.
