Four species of deep-sea marine invertebrates, coming from the vicinity of the Rockall Trough (Shetland-Faroe Channel), have been studied by means of gel electrophoresis. The degree of genetic polymorphism found would seem to indicate absence of correlation with the particular environmental factors which characterize the sampled area. The results suggest that the adaptive strategies of organisms belonging to different phyla are different.
