ABSTRACT
Deep ocean trawling between 200 and 2360 metres in the vicinity of Carson Submarine Canyon, Grand Banks of Newfoundland, reveals a moderately diverse assemblage of crinoids, asteroids, echinoids, and ophiuroids. No holothurians were taken. Vertical zonation is not pronounced. Faunal affinities are greatest with more northerly assemblages. When the fauna of this region is compared with that from the Hudson Canyon area, New York Bight, similarity, continuity, and coherence appear weak. The situation found in the echinoderms is not like that found in fishes. What deep ocean ecologists refer to as communities may be better considered random assemblages, predictable only in a very local sense.
