MA4-2324 - Hediste diversicolor, cirratulidés et Tubificoides spp. dans la vase sablo-graveleuse du médiolittoral

Hediste diversicolor, cirratulids and Tubificoides spp. in littoral gravelly sandy mud

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Sheltered gravelly sandy mud, subject to variable salinity. The infaunal community consists of the ragworm Hediste diversicolor, Pygospio elegans, Streblospio shrubsolii, and cirratulid polychaetes such as Tharyx killariensis. Nematodes and oligochaetes occur, as well as the bivalve Limecola balthica (Macoma balthica). Given the low sample numbers for this biotope, more records are needed to confirm the characterising species list.
Situation: It is probable that there are broad transition areas between this biotope and the corresponding muddy sediment biotope unit MA6-224. The boundaries may be very indistinct, with this unit present in patches of gravelly mud on areas of mudflat, where the main biotope is MA6-224.
