Description
This biotope is characterised by burrowing anemones (Cerianthidae), unidentified hydroids (Hydrozoa) and unidentified tube worms (Sabellidae) on bioturbated mud with phytodetritus. Video observations suggest there are many large burrows supporting associated unknown megafauna, the rare occurrence of seapens (Virgularia mirabilis) and also stalked sponges (Hyalonema) associated with this biotope.
