Excerpt: 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. Females can carry up to 680,000 eggs, which hatch after 10 weeks into flat phyllosoma larvae. These feed on plankton before the metamorphosis into the juvenile state. 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. In common with all spiny lobsters, the California spiny lobster has two large, spiny antennae, but no large claws on its legs. The California spiny lobster is one of the largest spiny lobster species, and grows up to 60 centimeters (24 in) long, but does not usually exceed 30 cm (12 in). Males can weigh up to 12 kilograms (26 lb). The upper side of the animal is brownish red, without the paler bands or spots seen in some other spiny lobsters. The legs are a similar color, but with one or more lighter streaks running along their length. Males and females of all ages can be distinguished by the position of the two round genital openings or gonopores. In females, they are at the bases of the third pair of pereiopods, while in males they are at the base of the fifth (last) pereiopods, furthest from the head and the closest to the abdomen. Mature females have a small claw on the fifth pereiopod, and enlarged pleopods. Th
