The bodies of spiny lobsters resemble true lobsters in terms of overall shape and the hard carapace. In contrast to the true lobsters, spiny lobsters are missing the dominant first pair of claws, as the first pair of legs are of similar size as the other legs. Their spiny antennae are a lot longer than those of the true lobsters. Spiny lobsters typically have a slightly compressed carapace, lacking any lateral ridges. The spiny lobsters are also known as langustas, cray fish or rock lobsters.

No species of slipper lobsters are registered in Norway.


This infra-order of Decapods includes spiny lobsters (family Palinuridae) and slipper lobsters (family Scyllaridae).
