Episode list

The award-winning team behind Penguins - Spy in the Huddle use hidden cameras to go into the heart of the dolphins' world, offering the chance to encounter dolphins up-close. The camera eyes of thirteen different 'Spy Creatures', including Spy Dolphin, Spy Nautilus and Spy Turtle, 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. In Mozambique, a newborn bottlenose dolphin learns from his mother as they follow a mysterious gathering of stingrays and then hunt huge kingfish. He practices his sonar, plays with bubbles and also discovers ways to dislodge pesky suckerfish.

Meet the orca, king of the dolphins, and discover the intimacy of its remarkable family life. Find dolphins that wear sponges on their noses, and race with the fastest dolphin in the world - the dall's porpoise.
