When I first heard it 1 was surprised as I thought sperm whales were the only species who used it.We can speculate the dolphins are using it for the same reason as the sperm whales,Berrow said.

They are regularly seen by passengers on the Shannon ferry and an estimated 25,ooo tourists every year take special sightseeing tours on local boats to visit them.
