From: Sponge diversity in Eastern Tropical Pacific coral reefs: an interoceanic comparison

In ETP we can find two different reef formations: Coral communities, defined as areas with scattered colonies or isolated patches growing directly on bedrock (A,B), and coral reefs, when a reef framework is developed (C). (D), Lower surface of B, showing different species of cryptic sponges (arrows). Images taken by JLC.
