Stout coastal shrimp (Heptacarpus brevirostris) : The stout coastal shrimp is an abundant species in tidepools, on docks and pilings, and under rocks in the mid to upper intertidal zone as well as in the shallow subtidal. The very short rostrum is distinct, as is the large robust maxilliped 3 (especially in mature males). Unlike other local shrimps with a short rostrum, this species has epipods on the first 3 walking legs.
Colorations observed vary greatly from red/white/green, tiger striped, mottled, or even a single large white stripe down their back. A bit larger than the Sitka Shrimp we carry, these Stout Shrimp average about 2" in size.
