Posted Sun Nov 22 2009: from BBC (UK):


	Acid oceans leave fish at more risk from predators http://apocadocs.com/s.pl?1258903516 Ocean acidification could cause fish to become "fatally attracted" to their predators, according to scientists. A team studying the effects of acidification - caused by dissolved CO2 - on ocean reefs found that it leaves fish unable to "smell danger". Young clownfish that were reared in the acidified water became attracted to rather than repelled by the chemical signals released by predatory fish.... In the test, the fish reared in normal water avoided the stream of water that their predators had been swimming in. They detected the odour of a predator and swam away from it. But, Ms Dixson said, fish raised in the more acidic water were strongly attracted to both the predatory and the non-predatory flumes.

Ocean acidification makes me a little crazy, too.
