What makes up only one percent of the ocean but is home to almost one fourth of all marine species?
Answer:
Coral Reefs
Coral Reefs
Home to millions of species of fish, crabs, starfish, clams, sponges, squid, lobsters, sea turtles, seahorses, and more, reefs have existed on earth for 400 million years.
Corals may look like rocks or plants, but they are actually animals that have taken 'root' on the ocean floor. Each coral is like a condo with hundreds of little animals (polyps) living in tiny compartments.
