Rock lobster

Spiny lobsters, also known as langustas, langouste, or rock lobsters, are a family of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, Ireland, South Africa, and the Bahamas, called crayfish, sea crayfish, or crawfish ("kreef" in South Africa), terms which elsewhere are reserved for freshwater crayfish. The furry lobsters (such as Palinurellus) were previously separated into a family of their own, the Synaxidae, but they are usually considered members of the Palinuridae. The slipper lobsters (Scyllaridae) are their next-closest relatives, and these two or three families make up the Achelata. Genera of spiny lobsters include Palinurus and a number of anagrams thereof: Panulirus, Linuparus, etc. The name derives from the small Italian port of Palinuro, which was known for harvesting the European spiny lobster (Palinurus elephas) in ancient Roman times. The town itself was named for the legendary figure of Palinurus, who was a helmsman in Virgil's Æneid.
