Coralline algae are red algae that form the order Corallinales within the division Rhodophyta.[1] Nongeniculate coralline algae have more than 1600 species that have been formally described.[1] Only one coralline species, Pneophyllum cetinaensis, is found in freshwater; the rest inhabit marine environments.[1]

Biology and range

Coralline algae are divided into two growth forms: geniculate (articulated) and nongeniculate (nonarticulated).[2] Coralline algae are widespread in all of the world's oceans, often covering close to 100% of rocky substrata.[3] They live from intertidal zones to 270 m water depth.[3] Only one strictly freshwater coralline species exists: Pneophyllum cetinaensis.[3]

Rhodoliths are free-living, rounded specimens that represent a non-attached growth form.[2] Coral reef ecology is significantly influenced by coralline algae.[4]

What the specialist sources record

The first coralline alga recognized as a living organism was probably Corallina in the 1st century AD.[5] In 1837, Rodolfo Amando Philippi recognized coralline algae were not animals and proposed the names Lithophyllum and Lithothamnion.[5] Since the time of ancient Greece, coralline rock has been employed as a building material.[6] Magnesium is typically present in the calcite, with its proportion depending on both the species and the water's temperature.[7]

A strong correlation was observed between crystal morphology in calcified cell walls and the results of molecular analyses.[8] Molecular relationships within the group are supported by morphological evidence derived from these skeletal structures.[8]
