There are over 160 different varieties of snakes in the rainforest.  Some live along muddy riverbanks.  The green tree boa makes its home in the trees.  Coral snakes live under stones or logs on the forest floor.

The biggest snake in the Amazon is the anaconda.  This dangerous reptile can get up to 20 feet long. Hungry anacondas hang about along riverbanks, waiting for their prey to come near the river.  They grab their prey and squeeze them to death.  After that they swallow them whole. 

Vipers are not as large as anacondas, they grow up to only 6 feet long.  But they are just as deadly.  Vipers use their sharp fangs to kill their prey, these sharp fangs inject poison.  Between their eyes and their nostrils many vipers have special pits, these pits help snakes sense their prey in dark places.  Vipers attack little animals such as lizards, but some can kill people too.
