Porolithon

Porolithon is a genus of calcareous red algae that plays a vital role in marine ecosystems. These algae produce calcium carbonate, which helps build and stabilize coral reefs and tide pools. They often form a hard, crust-like layer on rocks or other surfaces underwater, contributing to the reef's structure and providing habitats for various marine creatures. Porolithon is important for maintaining the health and resilience of coral reef environments, especially as they face threats like climate change and ocean acidification. In essence, it acts as a natural builder and protector within the vibrant underwater world.
