This video is quite amazing, I think the thing I find the most amazing in some ways is the way the animals strand themselves. They are just swimming along in a straight line and they don't deviate, then before they know it they are in trouble and the waves are washing them further up the beach.
I'm not sure if there are any other videos of dolphins stranding themselves, would be intersested if anyone knows of any.
On a side note while I think this is an amazing rescue, I'd be a bit worried about the possible damage done by dragging them by the tail. I understand common dolphins are very heavy (I've had to carry a few in my time), but teaming up into groups of 3-4 people and carrying them would have been a much harder but safer way of doing it! Still, at the end of the day, they got the job done!
It was just another day at the beach--or so it seemed till dozens of dolphins suddenly swam in with the surf and got stranded in the sandy shallows. The dramatic video of the stranding in the Brazilian town of Arraial do Cabo--now a YouTube sensation--shows humans rushing to help their fellow mammals, pushing and pulling hard to help the animals reach deeper water.
