Devious Defences

Series exploring bizarre behaviour in the animal kingdom looks at creatures that employ camouflage, armour and other methods to ward off predators. Discover skunks that handstand, crabs that dress up and fish that are slime monsters. Meet an armadillo that can roll into an impregnable ball, owls and frogs that puff themselves up and a cobra that spits venom. There are fish that can copy a chequered board, octopus that shape-shift and creatures that can turn inside out. There are even birds that use projectile vomit or repulsive missiles and creatures that turn playing dead into a performance to die for. Using new filming techniques and some extraordinary special FX, this is nature as never seen before.
