Dolphin cut free from fishing net by officer in moving footage

An American agent didn't hesitate for a moment when he received a call about a young dolphin that was in trouble off the coast of Miami, Florida. Nelson Silva immediately sailed to the marine mammal and tried to cut it free from the fishing net in which the dolphin was trapped. It didn't go smoothly: the strong animal was not at ease and occasionally struggled violently. The man's exploits have been widely praised on social media, where the video of the rescue was published. "Without you, the dolphin would have died," it sounds in one of the many reactions to the images. "Thank you!"
