American or European clawed lobsters are the classic lobster, with large, meaty claws. They are available live or as frozen lobster tails. You can also buy “culls”—lobsters missing one claw. Spiny lobsters have hard, rough shells, very long antennae, and no claws. Though there are many varieties of spiny lobster, most are sold under the name warm water lobster (from Florida, Southern California, or Hawaii) or cold water lobster (from Australia or New Zealand). They can usually be bought as frozen, uncooked tails. Smaller lobsters (scampi, langostino, slipper) are usually available only in restaurants.
