The bright colours of the coral snake warn that it is highly poisonous There are over 3000 kinds of snake in the world. Giants like the seven-metre long python can squeeze the life out of a large antelope and swallow it whole. Other snakes grow no longer than a pencil. Some live in the sea, some burrow underground, others climb trees. One species of fer-de-lance, a deadly viper, has been recorded swallowing prey that was 1.6 times its own body weight. Poisonous or harmless, large or small, all snakes - from the desert rattlesnake to the dwarf pipe snake - have certain things in common: a long, thin shape; scaly, legless bodies; and unblinking, lidless eyes. Like all reptiles, snakes rely on the heat of the sun to control their body temperature. That's why the greatest variety of species is found in the warm, humid tropical regions of the world. The venom of the king cobra, the world's largest poisonous snake, is strong enough to kill an elephant. | |
