Komodo dragon

The biggest and heaviest lizard in the world is the Komodo dragon. The bite of these lizards is poisonous, and among reptiles, they hunt in packs that are unusually cooperative. The tongue of a komodo dragon is long, yellow, and deeply forked. Their tail is also as long as their body. Their armored scales, which include small bones called osteoderms and serve as a form of organic chain mail, strengthen their typically gray skin. Komodo dragon skin is a poor supply of leather due to its tough hide. Additionally, as the Komodo dragon ages and grows, its osteoderms ossify more broadly and take on a wider variety of shapes.
