Every species has a secret weapon, a primal instinct that defines them - and it's not always as obvious as it seems.
These are stories of the planet's incredible killers, extraordinary lovers, amazing heroes, soldiers and savages. Personal stories of animals who, driven by instinct, have perfected the most astonishing and sometimes bizarre ways to give them the edge.
Through engaging stories of triumph and tragedy, each show features a number of animals to highlight a particular strategy for success and reveal the secrets of their survival.
Nat Geo Wild is on Starhub Channel 413 and Singtel Channel 207.
