Eastern Pacific tropical and sub tropical decapods (Macrura; Natantia). I. Vertical distribution and migration. A review

Abstract

Only recently have extensive collettioos beco made using trawls especially designed to sample deep-sea populations. The analysis of available information indicates that the caridean decapod biomass varies considerably in different parts of the ocean, being usually quite large at depths between 200 and 1,000 m. Among these decapods, the Pasiphaeidae, the species of Parapasiphae excluded, exhibit a shallower depth dístribution as compared with the red-colored Oplophoridae.
