We have seen animal rescue, but rarely have we seen the animal search for humans to save it!
On a night-time dive near Hawaii, 2 divers were found by a bottlenose dolphin and started to swim around them over and over again. When looking closer, one of them discovered the reason for this strange behavior - the dolphin had a fishing line hooked around it, hindering its ability to swim.
They cut him free, and the dolphin swam away, relieved. The fact that a dolphin would come to humans for help is once again evidence of its amazing intelligence, as most injured animals would never come close to a human and would actually be aggressive and defensive. This is amazing to watch and a life-time experience for those two divers, who got to share a moment of true understanding with a wild animal.
