BBC - Dolphins Spy in the Pod (2014) Part 2

The award-winning team behind Penguins - Spy in the Huddle use hidden cameras to go into the heart of the dolphins' world. The camera eyes of thirteen different 'Spy Creatures' allow behaviour to be captured that has never been filmed before, including a vast superpod of spinner dolphins hunting huge shoals of lanternfish while dodging the gaping mouths of giant rays.

Part 2: Remote-controlled Spy Creatures reveal dolphins as never before, as we meet the orca and discover the intimacy of its remarkable family life. There are also the dolphins that wear sponges on their noses, and the Dall's porpoise, the fastest dolphin in the world. There is the story of a real dolphin secret agent that carries a camera into the pod to uncover their mysteries of communication and interactions, and a young bottlenose begins a life on his own.
