Animal hunting and defense tactics that look more like engineering than instinct fill this BBC series on nature's stranger adaptations. One predator fires a glue gun at prey, a fish slashes with a chainsaw-like jaw, and a spider lassos its meal with a swinging blob of silk. A fish squirts water like a pistol to knock insects off leaves, a shrimp stuns prey with a burst of sound, and a mantis shrimp throws a punch that accelerates as fast as a bullet. A lemur taps trees with an elongated, ET-like finger to locate grubs, a frogfish snaps its mouth shut faster than the eye can follow, and a stoat is shown apparently hypnotizing a rabbit before striking. Elsewhere the camera catches salamanders shed from a truckload of tires rolling away like living wheels, a fulmar chick driving off a climber with projectile vomit, and a hagfish turning seawater into mucus to slip free of a fishing net. Each segment relies on slow-motion and close-up filming to make the mechanics of these behaviors visible.
