Tricks its prey by wiggling its tail

When it hunts, the eyelash viper wiggles its tail to attract prey. Then the tail looks like a worm or larva. When the prey comes, the viper strikes very quickly. The venom can be poisonous to humans but most people who receive medical attention survive. The eyelash viper eats and sleeps in trees.

Gives birth to live young

Look carefully and you will see that this snake has scales that stick out over its eyes. The scales look like eyelashes and that is why the snake is called the eyelash viper. Eyelash vipers come in many colours, including red, yellow, green, brown, and even pink.

The female carries eggs for six months. The eggs hatch inside her. When the small snakes, numbering from 2 to 20, have finished developing inside her, they are born. Then they are about 15 to 20 centimetres long.
