A video has captured the moment guests on a wildelife cruise out of Falmouth spotted blue sharks feasting on a dead dolphin.
Rhian Grey, who was out with AK Wildlife Cruises, said: "To encounter a dead dolphin in the ocean was very upsetting especially after watching the other common dolphins jumping and playing moments before.
"It was the last thing we expected to see on the boat. As we observed the individual dolphin floating in the water we noticed splashing and disturbance. Looking further we spotted sharks.
"These blue sharks had picked up on the scent of the dolphin and started to feed on the individual right next to the boat. I used this opportunity to put my underwater camera in the ocean to get some footage of this rare event.
