Otters aid Bangladesh fishermen

Bangladeshi fisherman feed their otters as they catch fish in Narail, some 129 miles from Dhaka, Bangladesh, March 11, 2014.

The fishermen are using a rare technique that relies on coordination between humans and trained otters, a centuries-old fishing partnership that has already long died out in other parts of Asia.
