It can be pre-ordered here from www.amazon.com now.

Dolphins: Spy in the Pod takes an in-depth look into the secret lives of a variety of dolphins as the specially designed “spycams” often interact and engage the curiosity of their subjects and film examples of their intelligence, communication, and relationships. 


A new generation of spy cameras enter the dolphins’ world shedding light on the hidden lives of the cleverest animals in the ocean. This time all the cameras are designed as ‘Spy Creatures’ most with cameras for eyes. They include Spy Dolphin, Spy Nautilus, Spy Turtle and a variety of other denizens of the deep. Working alongside the human dive team, they captured the most intimate views of dolphins that had ever been captured and filmed an array of new and remarkable behaviour.

The series first aired on BBC One in the UK in 2014.
