"During a manta ray dive, a bottlenose dolphin approached master scuba diver Keller Laros. It had fishing line wrapped around its pectoral fin and line coming out of its mouth. The dolphin cruised up to Laros and rolled over as he started to remove the fishing line while the dolphin patiently waited. Laros was able to free the pectoral fin, remove a fishing hook and cut the line trailing from the mouth before the dolphin swam away."
The dolphin needed help and knew that a scuba diver could provide that help. How cool is that!
