The video below shows a dolphin seemingly asking divers for help in untangling from a fishing line:
What is most remarkable is how the dolphin appears to know and trust that the divers can help it. First, it approaches them, and then, it positions itself to make removal of the line easier for the diver.
This example of the connection between people and other species may preview the type of interaction that we will have in the future. Interestingly, we are the ones having to develop the technology to understand dolphins while they seem to know us pretty well.
