Description
Biotope characterised by dense aggregations of the xenophyophore Syringammina fragilissima on coarse sediment. Associated species will vary with depth but may include squat lobsters (Munida), Ophiuroids, Majid crabs, pale encrusting sponges (yellow, white, grey, cream, pink) and sediment dwelling anemones. The same epifaunal assemblage is also found in the mid bathyal and on other sediments but associated infauna are likely to differ. Characterising species listed refer to all Syringammina fragilissima assemblages not just those found associated with the zone and substrate specified in this biotope.
