Often asked: Which Seafood Contains Corals?

What contains coral?

Most structures that we call “coral” are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps. Each soft-bodied polyp—most no thicker than a nickel—secretes a hard outer skeleton of limestone (calcium carbonate) that attaches either to rock or the dead skeletons of other polyps.

Where can corals be found?

Most reefs are located between the Tropics of Cancer and Capricorn, in the Pacific Ocean, the Indian Ocean, the Caribbean Sea, the Red Sea, and the Persian Gulf. Corals are also found farther from the equator in places where warm currents flow out of the tropics, such as in Florida and southern Japan.

Do corals feed fish?

Herbivorous fish feed on the algae that grow on corals and compete with them for light and oxygen.

Preserving our reefs will ensure we continue to enjoy the services they provide.

Is all sand fish poop?

No, not all sand is fish poop. Most of the sand material starts off in-land, from rocks. These large rocks break down from weathering and eroding over thousands and even millions of years, creating smaller rocks.

Why is coral so hard?

The coral species that build reefs are known as hermatypic, or “hard,” corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies. Other species of corals that are not involved in reef building are known as “soft” corals.
