Pandalus platyceros
Pandalus platyceros, also called California spot prawn (as well as Santa Barbara spot prawn and Monterey Bay spot prawn) or Alaskan prawn, is a shrimp of the genus Pandalus. Spot shrimp are a large shrimp found in the North Pacific. They range from the clean waters off Unalaska Island, Alaska, to San Diego. The commercial spot prawn fishery along the British Columbia coast is considered sustainable as they "occur in sufficient numbers to support several small commercial and recreational fisheries" and provides the largest landed value to the BC shrimp fishery. Distribution 
Pandalus platyceros are found throughout the marine waters of the North Pacific Ocean. While found living from 3.7 meters to 457.2 meters, spot shrimp are most often found around 109.7 meters below sea level. Description
