Talk:Coral

Template:FAOL Template:CnidariaProject I changed the phrase "Coral will also die if the water temperature changes by more than a degree or two and becomes too hot or too cold" because I felt it was misleading. It made it sound like if the current ocean temperature was 25C, then the coral would die if the temperature changed to 24C or 26C. This is not accurate since ocean temperature varies from summer to winter by as much as 5 degrees in the tropics where coral exist. What the statement should convey is that if the normal temperature range is between 20-25C, and if the ocean temperature rises to 26C or drops to 19C for a sustained period of time, then the coral will die. --Uw badgers 17:19, 14 Oct 2004 (UTC)

No need to explain improvements, and clearly you know about that of which you speak - Marshman 18:12, 14 Oct 2004 (UTC)

Just a word of warning - corals thrive at the upper limits of their temperature threshold and the limits for thermal bleaching varies significantly depending on the species and geographical location. Frequently corals thrive in 28C waters and only bleach when this threshold is exceeded by a degree. The severity and impact of bleaching is strongly dependant on both temperature and duration of the event, with additional factors such as UV penetration (cloud cover) and tidal regime.

Symbionts

Are the symbiotic algae interstitial or intracellular? What kind of algae are they? — Pekinensis 00:53, 14 May 2005 (UTC)[reply]

You can find answers at Zooxanthella. --Menchi 01:35, 14 May 2005 (UTC)[reply]

Corals not a taxon

I do not agree with your reasoning. "Coral(s)" is a common name, but common names are associated with specific taxa, and common name article titles that refer to a specific genus or even a species are used throughout Wikipedia. These common names are not really "taxa" either. The purpose of a taxobox (I think) is to provide taxonomic information down to the level that is reflected in the article. Thus, "fishes" has a taxobox showing how fishes are related to other vertebrates. I am reinstating, but welcome you and others to comment. - Marshman 18:11, 31 July 2005 (UTC)[reply]

Too quick?

I may have reverted your bad sentence before you had a chance to correct it. Sorry 8^) - Marshman 04:03, 14 December 2005 (UTC)[reply]

Animals?

Why the hech are corals considered animals? --71.241.159.88 12:22, 6 January 2006 (UTC)[reply]

Because they clearly are animals. Up close, they look like miniature sea anemones. Hermatypic corals do harbor algae, but these are symbionts living within the coral tussue - Marshman 18:33, 6 January 2006 (UTC)[reply]
