Stamina

A killer whale, a wolf and an ant go head-to-head in a race to eat. The first to get their daily intake of food is the winner. The three contenders have one thing in common - when it comes to hunting they all use stamina to help them catch their prey. Whether they trek a marathon in search of food or take on prey hundreds of times bigger than themselves, it seems nothing can stop them. Steve Backshall and Barney Harwood commentate on all the action as it happens.
