B3.114 - Niveau 5 : Blidingia spp. sur paroi verticale calcaire de la frange littorale
Description
Vertical soft rock in the littoral fringe may be characterised by a band of the green seaweeds Blidingia minima and Blidingia marginata. Unbranched filamentous green seaweeds, including Ulothrix flacca and Urospora wormskioldii, are found amongst the Blidingia spp. The siphonous Xanthophyceae Vaucheria spp. can also occur in high abundance in this biotope, where they can form dense mats. During low tide terrestrial fauna such as red mites, insects and centipedes migrate into this zone. More information is needed to improve this description. Situation: B3.114 is found below the Verrucaria maura zone (B3.1132) and above a band of the similar looking green algae Enteromorpha spp. (A1.451 and A1.452), where these occur in habitats not influenced by freshwater.
