The Alaskan King Crab is a very popular dish. There are many species of crab, both on land and sea, including the Hermit and Land crab. Although not hard-shelled like the crab or lobster, the octopus is still classified as a marine mollusk. Octopus have eight arms equipped with suckers, and a large head with highly developed eyes, and a very strong beak. Lobsters are found near most of the ocean's coasts.
Lobsters are marine crustaceans.
Clams are mollusks that live in the sea or in freshwater. Most live partly or totally buried in mud or sand. Go to Fish of the Sea. Click on the giant sea clam to see tropical fish, strange fish, and a school of fish. Ideal for school or home reference.
