Adult spiny lobsters make their homes in the protected crevices and caverns of coral reefs, sponge flats, and other hard-bottomed areas. The whole structure enables the insect to move the antenna as a whole by applying internal muscles connected to the scape. The terminal ends of crustacean antennae have two major categorizations: segmented and flagellate. Females are not monogamous. Re-amputation of the antennae caused a drastic decrease in flight stability to match that of the first amputated group. Lobsters grow by molting.

[2] The second antennae may be significantly reduced (e.g. Slipper lobsters have enlarged antennas, which are projected forward from the head as wide plates. The pedicel is flexibly connected to the distal end of the scape and its movements in turn can be controlled by muscular connections between the scape and pedicel.
