Most reef-building corals contain Photosynthetic algae, called zooxanthellae, live in their tissues. Corals and algae have a symbiotic relationship. Corals provide algae with a protected environment and the compounds they need for photosynthesis.

Do all corals have zooxanthellae?

Soft corals have no stony skeletons and Not always zooxanthellae. They can be found both in tropical oceans and in cooler, darker parts of the ocean. The coral reef-building corals survive by forming a symbiotic relationship with microscopic algae called zooxanthellae.

Where do you find zooxanthellae in corals?

The most common symbiotic relationship is with hard reef (or hermatypic) corals, although zooxanthellae can also find life within the tissues of soft corals, jellyfish, giant clams and sea slugs.

What are corals made of?

In fact, most of the structures we call « corals » are made up of hundreds or thousands of tiny coral organisms called polyps.Each soft polyp — most no thicker than nickel — secretes a hard exoskeleton Limestone (Calcium Carbonate) Attaches to dead bones in rocks or other polyps.
