Deep trouble--fish seeking colder waters may have nowhere to go

An increasing number of species are migrating in response to global warming; some alpine organisms are climbing to higher altitudes. Other animals are moving towards the poles.

A new study suggests that as sea temperatures rise, many fish may be electing to move into deeper, cooler waters, rather than moving to higher latitudes as many theorists had previously predicted. This presents a problem: the deeper the fish go, the less light and food they find.
