Caves, overhangs and surge gullys in Black sea infralittoral rock

Description (English)

Caves and overhangs in the infralittoral zone are completely submerged at all states of the tide. Light conditions are generally poor. Communities of sciaphillic algae, sponges and mussels are commonly present. Characteristic species: Phyllophora nervosa, Lomentaria clavellosa, Hildenbrandia rubra, Zanardinia typus, Mytilus galloprovincialis, erect sponges Halichondria panicea , Haliclona simulans, Dysidea fragilis, Dysidea pallescensor thin crust sponges like Antho involvens, Haliclona flavescens , Haliclona cinerea, Suberites prototypus, Clathria cleistocheila depending on current intensity, anemones Actinia equina, red mysid shrimp Hemimysis pontica, Hemimysis serrata and turf hydrozoans.
