 Flick of the Tongue - LP Zoo

This gaboon viper snake does do

A lot of tongue flicking so that,

Here at home in Lincoln Park Zoo,

It learns more of its habitat.

With each flicking the tongue forks out,

Gathering in scents from the air,

So more is known of what's about,

And leaving a smell trail of where

Potential prey or mate has gone.

And the viper can follow up,

Slithering toward till its upon

The object of its desire - yup!

All the choices to choose among

Start on the viper's tip of tongue.
