Biology & Habitat

Appearance

Caribbean spiny lobsters get their name from forward-pointing spines that cover their bodies to help protect them from predators. They have a reddish brown shell, marked with occasional dark spots and two large, cream-colored spots on the top of the second segment of the tail.

Biology

Caribbean spiny lobsters grow by molting—they vacate their old shells while simultaneously absorbing water, expanding their body size. They molt about 25 times in their first 5 to 7 years of life, and once per year when they’re older. It takes them about 2 years to grow to the 3-inch carapace (shell) legal-harvesting size.

Where They Live

Range Caribbean spiny lobster are found along the continental shelf of the southeastern United States from North Carolina to Texas, in Bermuda, throughout the Caribbean Sea, and south to Brazil. Habitat Caribbean spiny lobster live in shallow waters to depths of 295 feet, and occasionally deeper. Larval spiny lobster float in the water column.

Commercial Fishery & Harvest

In 2023, landings of Caribbean spiny lobster in the Gulf and South Atlantic totaled approximately 5.5 million pounds and were valued at approximately $43 million, according to the NOAA Fisheries commercial fishing landings database . Gear types, habitat, and bycatch: Commercial fishermen harvest spiny lobsters either by diving, bullynetting, or using wooden, plastic, or metal traps. Bullynetting is conducted in shallow waters at night when lobster are foraging for food or migrating offshore. A vessel uses a spotlight to find the lobster and then uses a “bullynet” to harvest the lobster. Buoys are attached to each trap, or if stringing a trap line, at each end of the trap line.
