Komodo Dragon

Komodo Dragons engage in violent mating battles but remain unharmed due to their protective scales. They inhabit a few Indonesian islands and are excellent swimmers. As the largest lizards, they can grow up to three meters and weigh 90 kilograms. These carnivores primarily consume carrion, using their forked tongues to detect carcasses from afar. They can eat up to 80% of their body weight in one meal and later regurgitate indigestible parts.
