Meet the spot prawn

The spot prawn is the largest shrimp in the U.S. West Coast. This shrimp has a big problem: it's one of the reef fishes' favorite foods. Though it hides 700 feet (213 meters) deep in rocky canyons, the prawn also falls prey to the commercial fishers of Monterey Bay.

Conservation

Spot prawns are popular seafood. For decades they've been caught in traps, which seems to have had little impact on their population. But as the demand for spot prawns grows, fishermen have begun large-scale harvests using trawl nets, which may both decrease their numbers and damage the habitat where they live.

Cool facts

  • Spot prawns change sex as they grow. They spend the first part of their lives as males, then change into females.
