Warmer oceans will shift habitats of marine animals
Warmer oceans will shift habitats of marine animals

Warmer water temperature and decreased levels of oxygen in the ocean will act together to push marine animals away from the equator to places in the ocean where the oxygen supply can meet their future needs, says a study.

When fish would experience 'mountaineering effect'

 Global warming would result in warmer water temperatures that would in turn speed up the aquatic animals' metabolic need for oxygen.
