Passage - "Uncharted" series

The reefs along our shores help keep our near shore waters clean from pollution. Many corals and sponges are filter feeders, meaning they consume particulate matter (pollutants that do not dissolve in water) in the water. This prevents these particles from settling on the bottom of the ocean and dirtying the ocean with harmful materials.

The water moves through the passages and channels through the reefs that live alongside our coastline.

The next time you take a dip in the ocean, drift along the coast don’t forget to thank the coral reefs for helping to keep it clean!
