camouflage and water absorbing.
Cuticle is a useful adaptation in plants but not algae because plants need a way to retain water and algae obtains water and other materials directly from the water around them.

an example of calcareous sponge is SPONGE BOB!
A calcareous shell is a hard, protective outer covering made primarily of calcium carbonate, found in organisms such as mollusks, corals, and some types of algae. It serves to protect the organism from predators and harsh environmental conditions.
Coralline algae is classed as a red algae. Red algae is unique because it has adapted to be able to photosynthesise not only in light (producing O2) but also in darkness and at night (producing CO2). This means that coralline algae can still thrive in low light, as long as the water has a high enough oxygen content.
Calcareous oozes form when the calcium carbonate shells and skeletons of marine organisms, such as foraminifera and coccolithophores, accumulate on the ocean floor. Over time, these calcareous remains compact and cement together to form a sediment known as calcareous ooze.
A calcareous sponge is any of a variety of sponge of the class Calcarea, with skeletons composed of spicules of calcium carbonate.
Calcareous ooze
They eat algae, aerate the gravel, and provide a food source for fish and other tank-mates.
