"Hot Vent" and "Cold Seep" Communities

Fig. 6.18 a, b. Typical infauna associations in shallow water in cold to temperate regions. Examples
are from the entrance to the Baltic Sea (Kattegart). a Venus association in sandy substrate at 10- 20
m water depth, with the sea star Astropeclen (I) , the sea urchin Echinocardium cordalum (2), the
bivalves Venus gallina (3), Spisula elliptica (4), Tellina labula (5), the polychaete tube-building
worm Peclinaria koreni (6), and the gastropod Natica (7). b Amphiura association in muddy substrate at about 20 m water depth with the brittle stars A. chiajei (/) and A. IUiformis (2), the snails
Turiella communis (3) and Aporrhais pespe/icani (4), the sea urchin Brissopsis Iyrifera (5) and the
polychaete Nephthys (6). Coastal regions in other regions of the world have other species, but the
basic make up of the associations persists ("parallel communities"). [G. Thorson , 1972, Erforschung
des Meeres, Kindler, Miinchen)
