Biology/Natural History: This shrimp is one of the crangonids I most commonly find in 100 m depth trawls in the San Juan Channel. Crangonids are often parasitized by bopyrid isopods such as Argeia. Crangonids are active predators, eg. on polychaetes. In Puget Sound some shrimp appear to be hybrids between C alaskensis and C. nigricauda.
