Superficially this species resembles Pandalus borealis, but is easily distinguished
by its long antennules and red and white striped abdomen. These stripes give the animal its common name of "side stripe" shrimp. The surface of the body is finely punctate. The rostrum is two to two and a half times the length of the rest of the carapace. There are 16 to 21 dorsal spines, three or four of which are on the carapace, those over the eyes are closely placed and on the remainder of the rostrum they are more distant. There are 9 to 15 inferior spines and the extremity of the rostrum is bifid or sometimes trifid. Next to Pandalus platyceros these are the largest shrimps.
Maximum depth from Ref. 79465. Larvae are pelagic, probably neritic. Juveniles and adults are sublittoral and bathyal (benthopelagic), found on green mud bottoms, sometimes on rocks. Food and feeding are yet to be described (Ref. 113898).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Larvae hatched in March or April, first three stages found in deep water. Males matured in the second autumn for about 18 months and remained sexually active for another year. Sex change began in spring, 3 years after hatching; become females (ovigerous) by autumn. Spawning occurs in the late fall and early winter, eggs carried throughout winter.
