Coral Skeleton Dwelling Endolithic Algae: Ostreobium and Its Biology
摘要
The coral skeleton is home to a highly diverse microeukaryotic and prokaryotic community, including algae from the genus Ostreobium: siphonous green algae living inside the calcium carbonate coral skeleton and visible as conspicuous green bands beneath the coral tissue. This alga’s broader potential functional role is a contemporary area of focus in coral reef ecology. This chapter summarises the current knowledge about Ostreobium biodiversity, its intriguing photobiology, microbiome, and functional role in the coral holobiont, and highlights some knowledge gaps related to the complex biology of this alga.
