Sabella pavonina with sponges and anemones on Atlantic infralittoral mixed sediment

Description (English)

Muddy gravelly sand with pebbles off shallow, sheltered or moderately exposed coasts or embayments may support dense populations of the peacock worm Sabella pavonina. This community may also support populations of sponges such as Esperiopsis fucorum, Haliclona oculata and Halichondria panicea and anemones such as Sagartia elegans, Cerianthus lloydii and Urticina felina. Hydroids such as Hydrallmania falcata and the encrusting polychaete Pomatoceros triqueter are also important. This biotope may have an extremely diverse epifaunal community. Less is known about its infaunal component, although it is likely to include polychaetes such as Nephtys spp., Harmothoe spp., Glycera spp., syllid and cirratulid polychaetes, bivalves such as Abra spp., Aoridae amphipods and brittlestars such as Amphipholis squamata.
