Abstract

Particle uptake and deposition by the 2 most abundant deep-sea demosponge species from the Norwegian and Greenland Sea (Thenea abyssorum) and the deep fjords of western Norway (Thenea muricata) were studied in flume experiments. Fluorescent particles of 1, 2, 3, 6, 10 and 16 mu m diameter (microspheres, Duke Scientific Corporation(R)) with a density of 1.05 g cm(-3) were used at 2 current velocities, 1.5 and 5 cm s(-1). Both species ingested small particles exclusively (
