Dolphins are known for their compassion towards humans, but footage has emerged showing just how useful a friends they can be.
The incredible moment a pod of dolphins chased off a shark to protect a group of divers was caught on camera in one of the world's most remote diving spots.
When Dennis Tierney set out to go diving off Lord Howe Island, Australia, his boat was quickly surrounded by a pod of dolphins.
After he and the other divers jumped into the water they were immediately surrounded by the dolphins, but circling deeper below them were a number of Galapagos sharks.
