A cuttlefish fires its tentacles at 32 metres per second to catch prey. The tiny star-nosed mole has the greatest sense of touch of all mammals. It's so sensitive that it can detect a grain of salt in a pile of sand. A ringed seal's whiskers are 10 times more sensitive than a cat's whiskers. Armed with ray guns, power drills, harpoons, minefields and even air bags these special agents have a licence to kill.
Gannets hunting for fish are like guided missiles.
Plummeting from 100 feet up they hit the water at 60mph - like smashing in to a brick wall. But they come up unscathed as their heads are designed to withstand the impact. Once it has locked onto its prey, a gannet steers its torpedo-shaped body with its wings, and just before impact folds them right under. Timing is critical as if it streamlines too late it will crash - the switch happens at precisely 0.82 seconds before impact every time. It also has a built-in airbag and a 'crash helmet' to cushion the blow.
