Speed Kills

Enter the rainforest's impenetrable understory, a damp world of shadows where the sun never shines and weird predators like velvet worms, big brown bats, and orange baboon tarantulas strike at lightning speeds. Witness these creatures' spectacular movements, too fast for the human eye to see, and discover their hunting secrets. We look under every rock and behind every tree in high-definition detail to reveal how these soldiers of evolution are geared to fight.
