In the competitive struggle for survival, less powerful animals have developed an ingenious array of strategies to find and kill their targets. Traps, lures and lies may be the best-known tricks to man, but are also skilfully employed by creatures in the animal kingdom. With weapons of deception, animals can disarm and entice prey to their death. Perhaps the oldest weapons employed by animals are projectiles, evolving their own versions of poison-tipped harpoons, chemical missiles and high-powered bullets. The creatures featured in this episode demonstrate the resourceful and inspired nature of surviving in the animal world.
