just when you thought it was safe to go back in the water – it is!

Rising ocean temperatures caused by global warming could make sharks significantly smaller and less aggressive, according to new research  carried out by Australian marine biologists.

“Warmer waters and ocean acidification will have major detrimental effects on sharks’ ability to meet their energy demands, with the effects likely to cascade through entire ecosystems,” said the study’s lead author, associate professor Ivan Nagelkerken.

“In warmer water sharks are hungrier, but with increased CO2 they won’t be able to find their food. With reduced ability to hunt, sharks will no longer be able to exert the same control over the marine food webs, which is essential for maintaining healthy ocean ecosystems.”
