Heat Waves, More Than Coral Death, May Cause Fish to Flee Reefs

Ilima Loomis, Science Writer by Ilima Loomis 25 July 201815 November 2022

A study over a broad swath of the Great Barrier Reef shows that warming waters directly cause fish and invertebrates to leave the reef, making it harder for coral to recover from bleaching events.
