It was long believed that animals only played to learn, only mated to reproduce and only took drugs by accident. But sometimes, they just do it for fun. Research has revealed that animals seek for pleasure just like humans do, and that there are many ways in which they enjoy themselves. Did you know that rats loved to play hide-and-seek? That primates played erotic games to ease tensions within their groups? Or that reindeers were quite fond of hallucinogenic mushrooms? Scientists show that this quest for pleasure - as wild as it can get - might even be a key of evolution and biodiversity. Combining the testimonies of international ethologists, scientific archives and sequences showing the animals in their natural habitats, this unusual documentary reveals the complexity of animal pleasure.

Des plaisirs pas si bêtes

Lizards do it.  Even fish do it. The animal world is showing us why play is a serious matter. Through a combination of ongoing experiments, reconstructed experiments and guided observation, 'The Power of Play' reveals surprising truths about play in the natural world. Scientists from Europe, the United States and Canada, many of them pioneers in the field, offer convincing evidence that play is not to be taken lightly. In fact, it has the power to make animals and humans smarter, healthier and more likely to survive.
