Notes
This and other amphipods can be distinguished from "true shrimp" (Order
Decapoda
) by having NO carapace, sessile eyes (no stalks) and three pairs of terminal appendages (uropods). Species of
Eurythenes
are the largest deep-sea amphipods and often are attracted to bait. Notice that there are large coxal plates at the bases of the legs - these are absent in decapod shrimps.
