To Ed Parnell:
First off I am a layperson whose only knowledge of corals is limited to the
ones I dive with in West Maui. I do however know some of them (entire coral
heads) quite personally. I can even tell you what year they got smothered
During a series of algae blooms (Cladophora) the corals that got killed off
the quickest were Pocillopora endouxyii and also Pocillopora meandrina.
While these corals would stand the pounding winter waves and yes, to some
extent even being blasted by sand and silt assaults, one season of
Cladophora blooms did many of them in.

I just checked what Acropora looks like in the book Living Corals. I could
not find cytherea but many of the Acropora species appear to have
finger-like branches and a rasp-like appearance.
In this respect they are as vulnerable to algae blooms as their Pocillopora
cousins. The Cladophora snags on the branches and does them in. While I am
not suggesting our dive site is typical of the Hawaiian Islands, I am
suggesting nutrient input and runoff are an increasing problem and MORE of a
concern than any pounding winter waves.
The decline of many Hawaiian corals has more to do with suspect-to-poor
water quality and lack of serious commitment to protect their ocean
environment than anything nature could toss their way.

Please correct me if I am wrong but I believe there was an interesting
transplanting study done on Oahu (Kaneohe Bay?) where Red Hypnea, a Florida
native was studied as a money "crop". As I heard it it was not feasible and
the plant was let loose. Other stories say it got loose.
Anyway, that Red Hypnea piles up in various parts of Maui every summer now
including our dive site. It is now so "successful" it has become a
permanent blight. I am in no way suggesting a coral could accomplish
something this impressive or fast in a little over a decade, I am just
pointing out the side-effects of many "introductions" inflicted on the

I can tell you with all due respect, I know of at least ONE.....
