slipper lobsters are a family (scyllaridae) of about 90 species of achelate crustaceans, in the decapoda reptantia, found in all warm oceans and seas. they are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. slipper lobsters are instantly recognisable by their enlarged antennae, which project forward from the head as wide plates. all the species of slipper lobsters are edible, and some, such as the moreton bay bug and the balmain bug ("ibacus peronii") are of commercial importance.
