New Records and Observations on the Flapjack Devilfish, Opisthoteuthis californiana Berry

Abstract

In June 1961 the U. S. Bureau of Commercial Fisheries joined with the Atomic Energy Commission to undertake an investigation of the deep-water ocean fauna in the area contiguous to the Columbia River mouth at depths from 50 to 1050 fathoms (91-1920 m). The main objectives of this project are to describe the benthic fish and invertebrate communities inhabiting the study area, and to define their bathymetric distribution on a temporal basis. Associated with the faunal investigation is a monitoring of the various demersal forms to evaluate the biological transport of radionucleids which may have their origin in Columbia River waters.
