In this video, a bottle nosed dolphin with limited mobility due to a hook and fishing line restricting a pectoral fin, approaches some divers for help. Diving instructor noticed that the dolphin was hanging around them, and that it wasn't able to move freely. Closer inspection revealed the ocean debris lodged in the fin.
The divers were able to remove the fishing line which allowed increased movement for the animal. Unfortunately, the hook was not able to be removed.
Thankfully, the dolphin not only allowed the divers to attempt to work the line and hook out
of the fin, but actually shifted its body to make it easier.
This is first time for me to see this type of video, even though the interaction between dolphins and humans is not new, but a this shows wild dolphins know that humans are tech animals and some time they help....
