A team of researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University found that larger fishes are becoming lazier as the ocean temperature rises because of global warming. They spend more time resting on the ocean floor, which I suppose would be the aquatic equivalent of laying in the shade. This could become a problem in future generations of fish because these lethargic fishes are less enthusiastic about finding food or mates. Fortunately, some populations of fish were able to adapt to the change in water temperature. We can only hope that the other populations of fish will follow and adapt as well. (Read more…)
