Newly settled abalone from 290 [micro]m to 2 mm were collected from crustose coralline algae (CCA) covered cobbles and boulders.
Vance (1979) found that the sea urchin Centrostephanus coronatus, a member of the Diadematidae family, avoids consuming crustose coralline algae when eating other algae, favoring development of coralline algae.
The fossil contents include sponges, echinoids, bivalves, coralline algae, pelecypod which are typical of an open shelf environment.
Similarly, their association with coralline algae, coral fragments, gymnocodiacean and udoteacean algae and echinoderms in the Cuautla Formation also indicates normal salinity (Flugel, 1982).
These consist of non-geniculate coralline algae, and some species of Peyssonnelia, mostly P.

Coralline algae are a key component of marine ecosystems and, as calcifiers that produce a high-magnesium calcite that is directly exposed to overlying water, these algae are particularly vulnerable to ocean acidification (Ordonez et al.
antillarum would be negatively correlated with macroalgal cover and positively with algal turf and crustose coralline algae at fore reefs habitats, considering that because of Jardines de la Reina is located far from human settlements and two thirds of the archipelago constitute a No-Take Marine Reserve with an effective protection, the study area can be consider as a "quasi-pristine" zone where nutrient concentrations and fish assemblages have been not affected by human impacts, thus they are not responsible for macroalgal overgrowth.
Jennifer O'Leary of the University of California at Santa Cruz and Tim McClanahan of the Wildlife Conservation Society found that reefs with large numbers of grazing sea urchins reduced the abundance of crustose coralline algae, a species of algae that produce calcium carbonate.
Structurally complex organisms like branching corals and coralline algae may commonly harbor protective symbionts that appear to suppress competitors and extend host ranges into more biologically stressful environments (see e.
