Freshwater is often the stage on which millions of animals gather to find a mate. And the cycle of freshwater is the trigger for spectacular mating rituals and fierce competition.

Jungles are home to 80% of all species but they cover just 2% of the planet. When animals in these crowded forests want to mate, the challenge is how to stand out from the crowd.

The Ocean is where life first experimented with the Mating Game, and over time this has led to some of the most ingenious mating strategies of all!

The grasslands of our planet are some of the most challenging habitats for playing the mating game. They are an open stage where potential partners and jealous rivals can witness your every move and every failure. To win here, a player must give everything. Strategies used by animals here are as plentiful as they are unique - there are show-offs, fighters, scoundrels and cheats, and all are competing for their chance to mate. Where grass is in plentiful supply, so too is the competition, and for those who gather in huge numbers to breed, the added threat of hungry predators looms large.
