Żyjące smoki Odcinek 2: Smart Reptiles

Are reptiles the bio-technology wizards of the animal world? If you count sprinting on water, shooting blood from their eyes, spitting poison at their enemies, navigating using magnetic fields, converting ribs into a hang-glider, or communicating emotions in colour, then yes, they are! 'Smart Reptiles' reveals surprising reptile behaviour stories and extraordinary bio-technology. Turret-eyed chameleons express their emotions in pulsating colour. Bellowing alligators send coded messages using infra-sound and show off by vibrating their flanks, causing water to dance on their backs! The sun-loving marine iguana turns its body into a storage heater and slows down its heart to enable it to feed ten metres down in a chilly sea. The green turtle uses tiny magnetic crystals in its brain to navigate across a vast ocean... Reptiles are master escapologists too: super-sprinting iguanas run on water; camouflaged dragon lizards suddenly spread vibrant wings to glide away through the forest canopy; armadillo lizards form a living wheel and roll to safety; and the spiky horned lizard even squirts blood from its eyes to repel attackers. But perhaps most remarkable of all are the snakes which use their forked tongue to sniff out their prey, then hug it to death, or destroy it with cell-busting and nerve-blocking chemicals. The ultimate snake, the king cobra, has even developed immunity to the venom of other snakes. Watch this programme and you will never underestimate a reptile again!
