Worldwide change in shallow reef ecosystems predicted as waters warm

A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research predicts that as the oceans warm fish — which appear to be superior predators in warm water — will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.
