Description

Iciligorgia schrammi is the largest of the sea fans and large specimens are much bigger than gorgonians. It is dichotomously branched in a single plane with the branches much further apart than other sea fans, giving it a ragged appearance. However, small specimens do not give this impression. The main branches are somewhat flattened and are 3 to 5 millimetres (0.12 to 0.20 in) in width. The polyps protrude from the edges of the branches. Their calyces are dome-shaped and have eight separate lobes. The polyps are stiffened with sclerites, which are curved spindles and rods which are arranged as a collar with pointed projections. The colour of this sea fan is usually light brown to bright red. Several brittle stars were associated with it in this habitat.[4][5]

Distribution

In the Atlantic Ocean, this species is found from south Florida southwards to Brazil, and in the Caribbean Sea and the Gulf of Mexico.[4] A single specimen was found in the South Atlantic Bight in Georgia in 2007 which is a northward extension to its range.[4]

Habitat

Iciligorgia schrammi normally grows at depths from 3 to 368 metres. It lives on vertical walls, standing out perpendicularly, and can also grow in deep water where the water is clear and the current high on slope breaks.[6]
