Spiny Lobster—General Facts

Commonly referred to as the Florida spiny lobster, the Caribbean spiny lobster inhabits tropical and subtropical waters of the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

Lobster illustration Commonly referred to as the Florida spiny lobster, the Caribbean spiny lobster inhabits tropical and subtropical waters of the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. Spiny lobsters get their name from the forward-pointing spines that cover their bodies to help protect them from predators. They vary in color from almost white to dark red-orange. Two large, cream-colored spots on the top of the second segment of the tail make spiny lobsters easy to identify. They have long antennae over their eyes that they wave to scare off predators and smaller antennae-like structures called antennules that sense movement and detect chemicals in the water.

Adult spiny lobsters make their homes in the protected crevices and caverns of coral reefs, sponge flats, and other hard-bottomed areas. The lobsters spawn from March through August and female lobsters carry the bright orange eggs on their undersides until they turn brown and hatch. Larvae can be carried for thousands of miles by currents until they settle in shallow nearshore areas among seagrass and algae beds. They feed on small snails and crabs. The lobsters are solitary until they reach the juvenile stage, when they begin to congregate around protective habitat in nearshore areas. As they begin to mature, spiny lobsters migrate from the nursery areas to offshore reefs.

Lobsters stay in their dens during daylight hours to avoid predators, emerging a couple of hours after dark to forage for food. While lobsters will eat almost anything, their favorite diet consists mostly of snails, clams, crabs, and urchins. The lobsters return to the safety of their dens several hours before sunrise.

The recreational fishery for the spiny lobster begins in July with a two-day sport season. This season is the last consecutive Wednesday and Thursday of July each year. Regular spiny lobster season is August 6 through March 31. For information on spiny lobster regulations during the sport season and the regular season, visit the FWC's Division of Marine Fisheries Management Lobster page.

It takes a spiny lobster about two years to grow to the three-inch carapace legal-harvesting size and they can grow as large as 15 pounds. The typical recreational harvest is 1.5 to 2 million pounds between the start of the two-day sport season and Labor Day. The commercial harvest averages 6 million pounds per season, with an average annual value of $20 million. Measured in dollars, the spiny lobster fishery is the largest commercial fishery in Florida.

Parts of a Spiny Lobster


Lobster Parts

Abdomen
the "tail" of the lobster; includes the large tail muscle covered with a segmented shell, the swimmerets, telson, and uropod

Antennae
the very long, whip-like structures attached just below the eyes

Antennules
much smaller than the antennae, thin and flexible, extend forward from under the eyes

Berry
female lobster carrying eggs under the tail is "in berry."

Carapace
the hard shell covering the cephalothorax

Dactyl
the last segment of a walking leg farthest from body; typically short and pointed

Larvae
independent early stage of an animal, typically very tiny and bearing no resemblace to the adult

Mandibles
the thick crushing "teeth" portion of the mouth

Phyllosome
the tiny, ocean-going lobster larvae that have hatched from eggs

Pleopods
swimmerets

Puerulus
a specialized larvae between the phyllosome stage and juvenile lobsters that lack mouth parts and swim from offshore areas to shallow nursery areas

Tailfan
the fan-shaped structure at the end of the tail, made up of the uropods and telson

Telson
the central part of the tail fan, somewhat rectangular in shape

Thorax
the central part of the body to which the walking legs are attached

Uropods
the outer, triangular sections of the tail fan; in lobsters two sections on either side of the telson
