A pair of divers off of the coat of Hawaii were shooting footage of manta rays got a surprise as they were working.

This amazing video shows a bottle-nosed dolphin approach the two divers for help. Upon inspection, a camera-wielding diver noticed that the mammal had fishing line wrapped around one of its fins.

The dolphin came in closer, allowing for the diver to cut the line… Watch this amazing video and see just how well this sea creature was able to understand commands and even position himself to help the diver perform his task!
