While the humans had a swim with manta rays in mind, a dolphin saw an opportunity to get the help it had been seeking.

In this video, a dolphin swims into a group of night divers there to watch manta rays gliding through the sea. It’s soon clear that the dolphin has something wrong: fishing line wrapped around its pectoral fin. Will it be able to communicate to the humans that it needs help? Will they be bold enough to help it?
