 Spiny lobsters are found in almost all warm seas, including the Caribbean and the Mediterranean Sea, but are particularly common in Australasia, where they are referred to commonly as crayfish or sea crayfish ("Jasus edwardsii"), and in South Africa ("Jasus lalandii").Spiny lobsters tend to live in crevices of rocks and coral reefs, only occasionally venturing out at night to seek snails, clams, sea-hares, crabs, or sea urchins to eat.Sometimes, they migrate in very large groups in long files of lobsters across the sea floor.
