Panulirus argus lives in the waters of the western Atlantic Ocean , in the Caribbean and the Gulf of Mexico , in the Bermuda region, off the Antilles, along the coast of America - in the United States starting from North Carolina and to the south - and up to the coast of Brazil. Caribbean spiny lobsters prefer coastal waters, but can also be found at depths of up to 90 meters. Their habitual environment is sea cliffs, reefs and underwater meadows from algae.
The average Panulirus argus is 20 centimeters, however, individuals are found that reach 45 centimeters. This species of spiny lobsters is nomadic, since in the beginning of winter spiny lobsters go into deeper waters. Since egg laying occurs several months later, other than reproduction reasons are more likely. For example, the migration of spiny lobsters is a relic of the ice age , when in winter they went into warmer deep waters. The movement of animals during migration is rather unusual: lobsters move in columns from several to two hundred individuals, one after another, while constantly maintaining contact between each other - the lobster located at the back constantly keeps its antennas on the dorsal carapace of the one in front [2] .
Egg laying of this species of spiny lobsters occurs in spring. The larva hatch from the egg at the latest stage - the mysis , which contributes to better survival [2] . An adult spiny lobster feeds on mollusks and sea urchins, which is ensured by the special two-chamber structure of its stomach, where the first chamber is grinding and the second filtering [2] .
