Epibiotic communities on sublittoral macroinvertebrates at Signy Island, Antarctica
The epibiotic communities on locally abundant macroinvertebrates, in particular the brachiopod Liothyrella uva and the limpet Nacella concinna , were examined from depths between 0 and 50 m at Signy Island, Antarctica. The percentage cover by epibionts on Liothyrella increased from <20% on the sm...

The epibiotic communities on locally abundant macroinvertebrates, in particular the brachiopod Liothyrella uva and the limpet Nacella concinna , were examined from depths between 0 and 50 m at Signy Island, Antarctica. The percentage cover by epibionts on Liothyrella increased from <20% on the smallest individuals to >50% on the largest, and decreased slightly with depth. The percentage cover of Nacella by epibionts increased with size of individual over an approximately similar range of values, but in contrast with Liothyrella increased greatly with depth. Cheilostome bryozoans and annelids of the genus Spirorbis formed >90% (by area) of the colonists on Liothyrella and 30–60% on Nacella , the coralline alga Lithothamnion and sponges making up the remainder.
