Except for the polar regions and a few islands, snakes have spread throughout the world. Religion has endowed snakes with mystical powers, invoking human emotions from reverence to outright fear. Though snakes are well-known among us, most of us find it difficult to accept their presence whether seen or not seen. Yet snakes are one of the great success stories of the natural world, having thrived on earth for a hundred million years longer than humans. Though snakes share a profound similarity in design, they are exquisitely well-adapted to the environment they live in. As long as snakes are not interfered with, there is no reason to believe snakes will not survive a hundred million years more.
NATURE’s The Reptiles: Snakes reveals the secrets, surprises, and strangeness of two-headed snakes and other amazing reptiles.
The Reptiles continues with a look at the reptiles that humans may fear most: Snakes. But the film does not portray snakes as evil creatures. Rather, it takes us into their secret and very strange world to try to understand them better. https://youtu.be/HJtG4STlGDs
Even though most snakes are not lethal to humans, many people are still terrified of these slithering reptiles. The program illustrates how venomous snakes bite humans only in self-defense and would much rather not confront us. Snakes also provide a valuable service by controlling the rodent population. https://youtu.be/HJtG4STlGDs
In the opening sequence, an aerial camera zooms in on a solitary Komodo dragon from afar. This, states Attenborough, is the last place on Earth still ruled by reptiles. Though they may seem primitive, reptiles and amphibians still thrive thanks to diverse survival strategies. In Venezuela, a pebble toad evades a tarantula by free-falling down a steep rock face. The basilisk, nicknamed the Jesus Christ lizard, can literally run on water and the Brazilian pygmy gecko is so light it does not break the surface. Reptiles are cold-blooded, and some have developed unusual strategies to absorb heat. Namaqua chameleons darken the skin of the side of their body facing the sun. A male red-sided garter snake masquerades as a female using fake pheromones, attracting rival males which help raise its body temperature and thus its chance of breeding. Malagasy collared lizards conceal their eggs by burying them, but egg-eating hognose snakes stake out their favourite laying sites. Niue Island sea kraits lay theirs in a chamber only accessible via an underwater tunnel. Other reptiles guard their eggs. Horned lizards drive off predators, but larger adversaries such as coachwhip snakes prompt a different reaction – the lizard plays dead. Komodo dragons prey on water buffalo in the dry season. They stalk a buffalo for three weeks as it slowly succumbs to a toxic bite, then strip the carcass in four hours. In Life on Location, the Komodo film crew tell of the harrowing experience of filming the dragon hunt.
