[Blu's Classroom] Crustose Coralline Algae | Marine Habitat & Species Micro-Documentary Part 4 ft. Ocean Conservation Administration & Keelung City Government

(Don't forget to turn on the subtitles!)

Pink coralline algae are commonly found on the surfaces of coastal rocky reefs. They absorb calcium from the water to form a calcareous structure. This hard algal body not only deters grazing animals but also anchors itself firmly to the substrate. Among them, "crustose coralline algae" typically grow by encrusting rock surfaces. As they continuously layer upon one another, they can form what is known as an "algal reef." Within the rugged and brittle algal reef, many burrowing organisms make their home — let's take a closer look through this marine habitat and species micro-documentary!
