A group of divers in Hawaii believes an entangled dolphin sought them out in order to get help.
Cameras captured the underwater rescue, and the divers say the dolphin swam to them, waiting for them to notice the fishing line stuck on its fin.
One of the divers used a knife to cut the line and free the dolphin.
The divers say they frequently go on dives to view manta rays off the coast of Kona, Hawaii, and will occasionally free entangled manta rays. They believe the dolphin has seen them help the manta rays and deliberately came to them for similar assistance.
