Komodo dragon

The Komodo dragon lumbers through the forest on its thick, stocky legs. It sways its head back and forth, flicking its long tongue as it searches for a daily meal. With its sharp teeth and surprising speed, the Komodo dragon is a top predator on the Indonesian islands where it lives. It might seem like a ferocious "dragon," but it's actually the world's largest lizard.
