The Corallinaceae are one of the two extant Coralline families of red algae; they are differentiated from the morphologically similar Sporolithaceae by their formation of grouped sporangial chambers, clustered into sori.
It protects beaches and lowlands and attracts tourists and other visitors who are able to scuba dive and snorkel in the protected marine area which contains the Coralline Reefs, as well as being a nesting ground for sea turtles.
Coralline Rock is a type of rock formed by the death of layers of Coralline algae.
It often grows in association with the crustose coralline alga Spongites yendoi and a filamentous red alga which it cultivates in a garden.
In adult shells the upper surface is invariably covered with algae, coralline and other, while the base usually supports a colony of Serpula.
