Black sea infralittoral sands and muddy sands with stable aggregations of perennial unattached macroalgae

Description (English)

Infralittoral sands and muddy sands with unattached forms of macroalgae, in particular the ball-like form of the red algaPhyllophora crispavar.sphaerica. The classic example of this habitat is the Small Phyllophora field (SPF) National Botanical Reserve, which lies in shallow water (less than 16 m) on sand with shells in Karkinitsky Bay, Ukraine. Characteristic species: Macrophyte species diversity is not high, comprising about 20 species, chiefly Zostera noltii and P. crispa. The Phyllophorabeds support a specialized fauna of more than 110 species of invertebrates and 47 species of fish that use the alga for breeding, food and shelter (many even having a reddish colouration). The main groups of macrozoobenthos recorded from the SPF in 2000 in terms of number of species, abundance and biomass were molluscs, polychaetes and crustaceans, with the most common species (with occurrence 60%) being: Mytilaster linneatus, Bittium reticulatum, Harmothoe reticulata, Nereis zonataandSynisoma capito.
