| - Chameleons
are colorful lizards known for their ability to change color, their long sticky tongue
and for their eyes.
- The
eyes of chameleons allow 360˚ vision - can move independently of each
other, giving the chameleon the ability to see all round itself when seeking
prey, and binocular vision in front when it is preparing to strike with its
long, sticky tongue
- Chameleons five toes are zygodactylous so they can grasp branches just like our thumbs and
fingers can grasp objects.
- The chameleon's tail can
wrap around tree branches while climbing. For this reason, the chameleon's tail
cannot be broken off and regrown like those of many other lizards
