Acid oceans leave fish at more risk from predators

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.

The findings were published in the journal Ecology Letters.

Danielle Dixson from James Cook University in Queensland, Australia, led the study.
