The California spiny lobster, Panulirus interruptus, is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California to the Gulf of Tehuantepec, Mexico. It typically grows to a length of 30 cm (12 in) and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species... Adults are nocturnal and migratory, living among rocks at depths of up to 65 m (213 ft), and feeding on sea urchins, clams, mussels and worms. The spiny lobster is eaten by various fish, octopuses and sea otters, but can defend itself with a loud noise produced by its antennae. The California spiny lobster is the subject of both commercial and recreational fishery in both Mexico and the United States, with sport fishermen using hoop nets and commercial fishermen using lobster traps..The California spiny lobster is found in parts of the Gulf of California, and along the Pacific coast of the length of the Baja California peninsula, extending as far north as San Luis Obispo Bay, California. There are occasional records from Monterey Bay, but the water there is too cold for the California spiny lobster to breed, and it is thought that any adult found in Central California arrived as a larva during El Nino years..California spiny lobsters are nocturnal, hiding in crevices during the day, with only the tips of their long antennae showing, as a means of avoiding predators. Towards dawn, the spiny lobsters form aggregations, which they maintain until dusk.[8] At night, they emerge and feed on sea urchins, clams, mussels and worms.[9] This activity is important in limiting sea urchin populations, and so maintaining healthy seabed communities
