Description
Definition Areas dominated by anemones (solitary coelenterates) that use their pedal disc to burrow in soft substrates. Many species are characterized by a whorl of tentacles at the sediment surface; when disturbed, the animal may very rapidly retract its tentacles into a burrow. These anemones occur at a range of densities, which requires sampling gear with an appropriate resolution and observational footprint (e.g., video transects or plan-view still photographs).
