Beware! the snake that slithers through the bushes.
It sheds in spring; the old layer of skin loosens.
Its head big, body thin with a heart of seven inches.
Its tongue is out, sniffing out prey to catch them.
To push on forward, it moves from side to side.
A rib-less tail that follows on behind.
A legless reptile, out there in the wild.
An ecologist's heart it surely doth beguiles.
