Prawns

A confusing turnabout in gastronomic appelation, the California spot prawn is really a shrimp, and the ridgeback shrimp is a true prawn. Without a doubt, both are delicious.

Spot prawns are aptly named for the four bright white spots on their bodies. Commonly found from Alaska to San Diego, spot prawns inhabit rocky and adjacent areas at depths from about 150 to 1,600 feet. These prawns begin life as males then change sex to female after about two years, as they near spawning age. Spot prawns live about six years, reaching six inches in length. Monterey fishermen trap spot prawns yearlong; southern California trawlers fish for spot prawns during summer, and switch to ridgebacks in winter.

Ridgebacks, sometimes called Santa Barbara shrimp, are found from Monterey to Baja California and are fished primarily in the Santa Barbara Channel. The ridgeback's life span is about 4 years, and the sexes remain separate. With their sharp, spiny shells, "ridgies" are the dickens to peel but may be the sweetest tasting prawn on the West Coast.
