Spiny lobster — also called rock lobster, langouste or crayfish (in Australia and South Africa) — is the sweet, firm tail meat of a clawless marine crustacean armoured in spines and trailing two enormously long, whip-like antennae. Lacking the heavy claws of the true lobster, almost all of its meat is in the muscular tail, which is why "lobster tails" the world over are usually spiny rather than clawed lobster.
