Interactions between sediment chemistry and frenulate pogonophores (Annelida) in the north-east Atlantic
The small frenulate pogonophores (Annelida: Pogonophora a.k.a. Siboglinidae) typically inhabit muddy sediments on the continental slope, although a few species occur near hydrothermal vents and cold seeps. We present data on the distribution and habitat characteristics of several species on the Euro...
