Sphenotrochus andrewianus - Wedge Coral

Range & Status

A small solitary species of cup coral found living unattached in shell gravel in depths to 100m. Whereas this species has been recorded in the past on all coasts of the British Isles, it has not been seen in any of the recent major dive surveys. It is not easily found, unless deliberately looked for due to its small size and camouflage within its habitat. Specimens were collected in the vicinity of the Manacle Rocks (Lizard Peninsula) in the 1980s and 1990s.
