damselfish in distress!

A study from scientists at James Cook University shows increased carbon dioxide levels impaired the senses of spiny damselfish, which live in the Great Barrier Reef.

Fish exposed to higher carbon dioxide levels – which are expected to increase in the oceans for several decades – showed impaired cognitive function, learning difficulties, slowed visual capacity and altered sense of smell and sound.

The damselfish also lose their ability to recognise threats, including the smells of predators when exposed to higher levels of carbon dioxide – and will even become attracted to them instead. Sydney Morning Herald, 6 Oct 2014
