Abstract Constructional lips and cup reef rims are little studied reef features typical of very turbulent conditions. The relatively low diversity community of these structures consists of three components, and algal mat dominated by Herposiphonia secunda, an encrusting calcareous biota characterised by crustose coralline algae and the vermetid gastropod Dendropoma corrodens, which together are the main hermatypic components, and an endolithic component with very abundant boring sponges, polychaetes, crustaceans and sipunculids. In northerly areas of Bermuda, the hydrozoan Millepora alcicornis is a prominent member of the community while to the south the urchin Echinometra lucunter is abundant. On the south side of Bermuda the community traps sediment which is deposited in the void spaces. The environment shows reduced grazing and this may account for the presence of several relict and rare species.
