The komodo dragon's mouth is a dentist's nightmare. Since the Komodo is a rare and threatened animal it is protected on an island of Komodo by the Indonesian government. The lizard has a long forked tongue, much like a snake's is. Komodo Dragons are extremely territorial. The losing male has to stand still, while the winner scratches its back in a painful manner.
Monitors are among the oldest living lizard.
They are sleek, fast runners with tapered heads, long necks, strong legs, and long, powerful tails.
