Black sea circalittoral dark caves and tunnels

Description (English)

Caves and overhangs in the circalittoral zone are characterised by a lack of light. All around the Black Sea this habitat type occurs mostly on limestone but it may also occur onvolcanic and metamorphic rocks. Characteristic species: Turf hydrozoans, thin crust sponges like Antho involvens, Haliclona flavescens, Haliclona cinerea, Suberites prototypus, Clathria cleistocheiladepending on current intensity, anemones Actinia equina, red mysid shrimp Hemimysis pontica, Hemimysis serrata and the rare shrimp species Palaemon serratus and Lysmata seticaudata
