Shallow muddy sediments, often with boulders, cobbles and pebbles around the edges of lagoons that are exposed to wide salinity variations are unsuitable for colonization by many species. Such areas may be colonized by a dense blanket of ephemeral green algae such as Ulva spp., Chaetomorpha linum, Cladophora liniformis or Derbesia marina. This biotope may also contain some red seaweeds, such as Furcellaria lumbricalis, but always at low abundance (compare with SIR.PolFur). Amongst the filamentous green algae, grazing molluscs and solitary ascidians may be present.
