chaos as ocean fills with dizzy fish

Young coral reef fish with misshapen ear bones are more likely to get lost and die, and exposure to warmer waters makes the problem worse, according to a study of fish living around Lizard Island on the Great Barrier Reef, Australia.

Monica Gagliano at the Australian Institute of Marine Science in Townsville, Queensland. Gagliano says that as-yet-unpublished work shows that exposing adult reef fish to higher water temperatures and increasingly acid water – both of which are associated with global warming – increases the percentage of offspring born with asymmetrical otoliths.
