Spiny lobsters lack the large front claws of the American lobster and are prized instead for their tail meat, which accounts for 33 percent of the body weight. Some 30 species of spiny lobster are found in tropical and subtropical waters around the world. They are marketed in the United States as either warmwater or coldwater tails, depending upon where they were captured. Brazil and the Caribbean are the main sources for warmwater tails; Australia, New Zealand and South Africa supply coldwater tails. Panulirus and Jasus species are the most valuable lobsters commercially. The Caribbean lobster, P. argus, is the main warmwater tail on the U.S. market, and P. cygnus from Australia is the main coldwater species. Rock lobsters average under 5 pounds; translated into tails, the range is 5 to 22 ounces, with most product under 8 ounces. The lobsters are captured mainly in baited traps but are also caught in trawls or by divers.
