A new generation of spy creatures search the ocean for intelligent life and find ways of thinking that have to be seen to be believed. The most complex spy creature ever built films the owner of the largest brains on the planet – sperm whales. Spy Whale is the same size as a new-born whale calf and is equipped with an array of cameras.

Our spy creatures dive into the world of animal emotions by befriending the most complex minds in the ocean and gaining insights into their innermost feelings. Bottlenose dolphins are famed for their intelligence, but Spy Dolphin is on a mission to find out what they really feel. Spy Dolphin is prepped and ready to join a pod of thrill-seeking dolphins surfing the waves.

Spider crabs rise up from the abyss in their thousands to shed their protective shells, but as our Spy Crab soon discovers, this makes them an easy target for hunting stingrays. There’s protection in numbers, however, and those still with armoured shells form a crustacean fortress that protects the vulnerable crabs inside.

Spy Whale is joined by Spy Dolphin as they encounter a humpback whale calf in danger of drowning when competing males pursue its mother. After a remarkable effort from the calf’s parent, she not only manages to protect her baby from danger, they also gain a bodyguard!
