Invertebrate dominated exposed Black sea mediolittoral rock
Description (English)
Exposed mediolittoral rock zone in the microtidal Black Sea (tide range approx. 0.3 m) is limited to a narrow strip which receives regular but not continuous submersion. In such situations the abiotic conditions (i.e. waves, variations in atmospheric pressure and variations in wind) define the species composition. These conditions mean that there are few associated species and those which are present are typically encrusting, tolerant to desiccation, and capable of very firm attachment. They include barnacles, lichens and small mussels, crabs may be found in sheltered crevices.
