Leathery sea fan
awaiting identification*
updated Oct 10

Where seen? This bushy colony with thick, fleshy branches is often seen on reefs on our Southern shores. On the reef flats and at reef edges, usually among living corals. Usually, only one colony is seen on a reef.

Features: Colony bushy 50cm-1m wide, with stems that are long and not frequently branched. Each stem is cylindrical, thick (about 1cm in diameter) and fleshy with a texture that resembles leathery soft coral (Family Alcyoniidae). Each stem has a dark wire-like central support that is sometimes exposed at the tips. Usually dusky pinkish beige. Fat polyps are about 1cm long.
