In her last moments, this female chameleon's skin erupts with color. All that remains are her eggs, buried deep beneath the surface.

The Big Little Journeys team travels through storms and fallen trees to reach the remote Kirindy Forest in Madagascar. Here they work with local scientists to film the short-lived journey of a matchstick-sized chameleon. Its life is finely in tune with the seasons and the team discovers how this leaves them vulnerable to the effects of a warming world. Narrated by Aaron Pierre.

A female chameleon draws the attention of two males. They must battle it out to prove their worth to her.

On her quest for a new home, the water vole encounters a body of water. In the cold waters beneath her, monsters lurk.

In Madagascar’s Kirindy Forest, a matchstick-sized chameleon goes on an epic journey through high trees and ground floors to find a mate and lay eggs before it’s too late. A water vole in the Scottish Highlands swims a lake, climbs a waterfall and scales a mountain also to find a suitor and a place to raise her pups.

After following a fertile female for hours, this young male pangolin proves himself worthy of mating. But mating in a suit of armor isn't easy.

The Big Little Journeys team works with conservationists to follow the journeys of two endangered animals as they navigate a world transformed by humans. A rescued pangolin in Taiwan is given a new chance back in the wild, whilst scientists using radio collars follow a family of Golden-headed lion tamarins, with newborns, through Brazil’s Atlantic forest.

A monkey-eating Harpy Eagle, 15 times the weight of a Lion Tamarin, circles a tamarin family. With nightfall fast approaching, the family can't turn back...they must find a way to cross an open road to escape.

In Taiwan, a Formosan pangolin travels through a land of giants to find a mate in a protected forest. The lonely male encounters dangerous and strange characters along the way, from a cobra to a Formosan moon bear. In Brazil’s Atlantic Forest, a family of golden-headed lion tamarins, searching for food, journey to a land of plenty and face an ocelot and a monkey-eating harpy eagle in their path.

The Big Little Journeys team employs various filming techniques to follow the journeys of two very different animals. New probe lenses and motion control systems are used to see the world from the perspective of a walnut-sized turtle and follow its journey through a Canadian woodland. In South Africa night vision cameras and gyrostabilized cranes are used to keep pace with a nocturnal bush baby.

This young bush baby learned from his mother where to find an important winter food: acacia gum. A large and reliable source can be found half a mile away, but he must navigate through the dense forest to get there.

For a tiny bush baby, danger lurks around every corner in this forest. The bush baby's scent is picked up by a genet, one of the few predators adept enough in the trees to catch a bush baby.

In Canada, a walnut-sized turtle ventures through a forest of giants, dodging huge trucks along the highway. The newly hatched turtle is in search of the lake where she will spend the next 50 years of her life. In South Africa, a young bushbaby is expelled by his family and must journey into the unknown to find a new home. He is drawn toward the lights of the human world in the city of Pretoria.

Spy Crab joins a male peacock mantis shrimp on his hunt. Despite his size, peacock mantis shrimp packs the most powerful punch in the world.

A male humpback whale looking to mate is called a singer. When a group of singers threatens this mother and her calf, she will do whatever it takes to protect her calf.

Spy creatures showcase the challenges of ocean life. From a baby whale in danger and marine iguanas battling storms, to a mantis shrimp’s knockout punch, the spies are never far from trouble.

Spy Dolphin captures one of the greatest dolphin megapods ever filmed. United, they can hunt as a super team.

As the storm builds, lobsters gather together for safety. They form a chain that becomes a "lobster conga line."

Spy creatures uncover surprising undersea relationships as sharks befriend fish, whales play with dolphins, and lobsters do the conga in seas where even spider crabs have friends.

The skin of a cuttlefish shows its emotional state. Its color may change when meeting a potential mate or a rival. But what happens when a male cuttlefish interacts with Spy Cuttlefish?
