A group of fisherman off the coast of São Paulo, Brazil, had their Nov. 15 fishing trip transformed into a rescue mission for one adorable creature of the sea. In a dramatic video uploaded to YouTube, the fishermen spot a young dolphin caught in a plastic bag. The anglers use a net to pull the calf onto their boat to help it out. After a few tries, they are finally able to free the dolphin from the plastic bag:

Once the dolphin is released back into the ocean, it appears to jump out of the water for joy, which many people on the Web think was its way of thanking the fishermen. In another video that has people thinking that dolphins try to communicate with humans, a dolphin entangled in fishing wire approaches a diver in what some think is a sign that it is asking for help:

Both cases remind us that we need to protect the ocean and the animals that call it home.
