A GROUP of scientists have discovered that whales have a sense of smell.

Before now it was thought that whales and dolphins weren’t able to smell at all. However the study by scientists in Ohio, Japan and Alaska reveals that Bowhead whales actually smell the air.

Experts feel the mammals use this to sniff out their prey of krill – which actually smell like boiled cabbage.

If this is the case then there’s a worry that human pollution, which masks ocean scents, could impact on the endangered species.
