zooxanthellae and coral relationship poems

However, the symbiotic relationship between coral polyps and zooxanthellae algae is only functional within a narrow range of water. Corals have a symbiotic relationship with a tiny marine algae called Symybiodinium, or zooxanthellae, that live inside and nourish them. Coral reefs have been called the rainforests of the ocean. and symbiotes, the microscopic zooxanthellae that help corals feed. used reefs as metaphors to think about relationships, embodiment, sensation, and ecological entanglement. The stanzas published here are drawn from a book-length poem.

In exchange, they have a place to live inside the animal's body. But when the zooxanthellae are under stress, such as high temperatures, they will die or leave their host—a process known as bleaching. Close-up of a Coral Polyp Credit: The brownish-green specks seen in this coral polyp are the zooxanthellae that most shallow, warm-water corals depend on for much of their food.

Like plants, zooxanthellae capture energy from the sun and turn it into food, some of which the coral eats in exchange for protection. Where Do They Live?

Smithsonian Institution As you can see in this diagram, the zooxanthellae live within the tissue of their host coral. What started in our Los Angeles living room eight years ago has grown steadily into a worldwide happening that now encompasses more than 30 individual crochet reefs in cities and countries as far flung as New York, Chicago, Scottsdale ArizonaSt.

More than 7, people have actively contributed to these giant wooly installations, which have been exhibited in both art galleries and science museums: The latest addition to this threaded archipelago of Satellite Reefs is currently being constructed in Abu Dhabi, the first in the Middle Eastern and a region with its own unique coral systems.

Middle East corals grow naturally in warmer temperatures than most other reefs and are now being closely studied for clues as to if and how corals might adapt to global warming.

What we know as a head of coral is actually a colony of thousands of polyps acting together. Individual polyps are tiny brainless jellyfish-like organisms floating in the sea; only en masse do they acquire their astonishing generative powers.

Collectively, a colony of genetically identical polyps constructs a gastrovascular system through which members share nutrients and symbiotes, the microscopic zooxanthellae that help corals feed. Together the colony breathes, eats, and develops a sexual reproductive cycle.

What is coral bleaching?

Thousands, or millions, of heads of coral collectively form a reef, which protects coastlines, feeds humans, and provides a home for millions of other species. If reefs were to disappear, as scientists are beginning to warn might happen, ecosystem collapse may result. Most importantly, zooxanthellae supply the coral with glucose, glycerol, and amino acids, which are the products of photosynthesis.

The coral uses these products to make proteins, fats, and carbohydrates, and produce calcium carbonate Barnes, R. The relationship between the algae and coral polyp facilitates a tight recycling of nutrients in nutrient-poor tropical waters.

In fact, as much as 90 percent of the organic material photosynthetically produced by the zooxanthellae is transferred to the host coral tissue Sumich, This is the driving force behind the growth and productivity of coral reefs Barnes, ; Levinton, Coral polyps, which are animals, and zooxanthellae, the plant cells that live within them, have a mutualistic relationship.
