Entangled dolphin asks diver for help

KONA, Hawaii (CNN/OCEAN WINGS HAWAII) - Divers in Hawaii lend a hand to a needy dolphin.

In the video, you see a bottlenose dolphin approach a diver who notices his fin is entangled in fishing line.

The diver uses a knife to cut away at the line, freeing the dolphin.

The group was on a night dive to view manta rays off the coast of Kona, Hawaii.

They say they've helped free manta rays from entanglement before and that the dolphin showed interest in getting some help for himself.
