Spiny lobster
Although they superficially resemble true lobsters in terms of overall shape, and that they also have a hard carapace and exoskeleton, the two groups are not closely related. Spiny lobsters can be easily distinguished from true lobsters by their very long, thick, spiny antennae, and by their complete lack of claws (chelae); true lobsters have much smaller antennae and claws on the first three pairs of legs, with the first being particularly enlarged. Like true lobsters, however, spiny lobsters are edible and are an economically significant food source; they are the biggest food export of the Bahamas .
