Male Komodo dragons also have larger heads and wider necks than females. This is because males use their heads and necks to fight each other for dominance and territory. Males also have larger, more powerful jaws and teeth than females. These features are used for hunting and defense.
In addition, male Komodo dragons have a pair of spurs on their hind legs that females lack. These spurs are used for defense and can inflict serious injuries.
Finally, male Komodo dragons have a unique scent gland on their chins. This gland releases a pheromone that attracts females during mating season.
