Scientists have called into question an idea that the bodies of cold-blooded marine animals, such as fish, will shrink in a warming world.
A study published last week said that aquatic animals such as fish would actually grow larger due to warm water pollution, i.e. water heated by warm pollutants.
As the planet warms, scientists had expected that cold-blooded animals, or ectotherms, would grow faster at a younger age but reach smaller body sizes as adults. They had observed this pattern in small-scale studies, including in natural settings.
