The phylogeny of box crab genera (Crustacea: Brachyura: Calappidae) with notes on their fossil record, biogeography and depth distribution.
Red rock and box crab are sometimes sold in Northwest markets.
The main by-catch species, in terms of weight, were South Pacific hake (Merluccius gayi) (4.0 ton, 8.8%), bigeye flounder (Hippoglossina macrops) (1.7 ton, 3.7%), yellow squat lobster (Cervimunida johni) (0.9 ton, 2.2%), and armored box crab (Mursia gaudichaudi) (0.8 ton, 1.7%).
Recent study of those crustaceans has produced one genus (Cyclozodion) and two species of box crabs (family Calappidae) in the Northwest Atlantic new to science.
