n. pl. zo·o·xan·thel·lae (-thĕl′ē)
Any of various yellow-brown photosynthetic dinoflagellates that live symbiotically within the cells of other organisms, especially certain corals and other marine invertebrates.

[New Latin : zoo- + xanth(o)- + -ella, diminutive suff.]

Three interesting exhibits are the zooxanthellae (or "zoox"), plantlike organisms that live inside coral polyps, gobbleguts, a type of cardinal fish, and the anemonefish--can you find 'Nemo'?
Petchey and Clark (2011) suggest that a symbiotic relationship with zooxanthellae may reduce the reservoir effect in Tridacna shells but only by c.
In one of the first activities, individuals played the roles of coral polyps, zooxanthellae, the algae that feed the corals, and the protective calcium carbonate skeleton.
She teams up with the Zoox, a family of slow but steady zooxanthellae marine plankton.
Reduction of coral growth may occur when precipitation of calcium carbonate to form the coral skeleton is altered by deficiency of available light (due to excess of suspended sediment in the water column) to the zooxanthellae (endossimbiont algae) that makes photosynthesis, or due to the excess of energy that the corals use to remove sediment from their polyps.
These organisms thrive in shallow, sunlit waters of coral reefs and derive their nutrition by filter feeding, as well as via transfer of photosynthetic products from their symbiont, the zooxanthellae Symbiodinium sp.
Carotenoids of clam, coral and nudibranch zooxanthellae in aposymbiotic culture.
Zooxanthellae are densely packed within coral skeletons--one million of them per cubic centimeter.
Ritchie is proposing that a third player may be involved in the relationship: symbiotic bacteria that help keep corals, and perhaps zooxanthellae, healthy.
Ancient single-celled algae also live inside the bodies of living corals in the Florida Keys, known collectively as zooxanthellae (zo-o-zanth-elli).
As ocean temperatures rise, a very important algae called zooxanthellae (zoo-zan-thel-y) that provides food for corals--and contributes to their remarkable colors--can no longer make food.
Over months of fieldwork, study and analysis, Dr Jones and Dr Berkelmans assessed both the survival and regeneration potential of specific coral species and their zooxanthellae (4) (algal) symbionts.
