Extract

Since the first visual observations of hydrothermal vents in the Eastern Pacific in 1976 (Lonsdale, 1977) these areas of the sea bed have been characterized by their spectacular, and in most cases, novel fauna. Of the 236 macrofaunal species described from hydro-thermal vents, 223 were new to science according to the most recent estimate (Tunniclif f e, 1991), although there are many species still awaiting description. The vent areas are characterized not only by the organisms present but by those which are apparently absent. Absentees include sponges, brachiopods, bryozoans, echiurans and echinoderms, although the last phylum is represented by occasional sightings of echinoids, ophiuroids and holothurians (Grassle, 1986; Tunnicliffe, 1991; Segonzac, 1992).
