Can dolphins reveal why whales strand?

Researchers in the US are working with dolphins in an effort to work out why closely related whale species in the wild strand themselves on land.

The team, from the University of California Santa Cruz, carried out experiments to measure the effect on the animals of human-made noise, something that has been implicated in mass strandings.

The findings are published in the Journal of Experimental Biology.
