Toxic algae rapidly kills coral http://apocadocs.com/s.pl?1286646837
Scientists studying coral reefs in the Gulf of Oman have issued the warning after being shocked by the impact of one large-scale bloom, which destroyed a coral reef in just three weeks.
Around 95 percent of the hard coral beneath the algae died off and 70 percent fewer fishes were observed in the area.
The rapidly growing patches of microscopic marine plants starve coral of sunlight and oxygen. Coral reefs are increasingly under threat from environmental stress in the form of climate change, coastal development, overfishing, and pollution. Climate change is suspected of causing a number of coral bleaching events, as rising sea temperatures stress coral communities. But the latest study, published in the journal Marine Pollution Bulletin, suggests that algal blooms could pose another significant threat.

Sounds like the algae is just putting the coral out of its misery.
