MB1-263 - Hartlaubella gelatinosa et Conopeum reticulum sur substrat hétérogène en milieu à faible salinité de l'infralittoral en Atlantique

Hartlaubella gelatinosa and Conopeum reticulum on low salinity Atlantic infralittoral mixed substrata

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Upper estuarine mixed hard substrata colonised by very sparse communities of animals with low species richness and with a few seaweeds in very shallow water. In some sites, the hydroid Hartlaubella gelatinosa and bryozoan Conopeum reticulum are found on stones. In others, the bryozoan Bowerbankia imbricata is most abundant. The mussel Mytilus edulis, the crab Carcinus maenas and the hydroid Obelia dichotoma can be present. There are considerable differences in species composition between sites, but all occur in brackish turbid-water conditions. More information required to validate this description.
