Komodo dragons (Varanus
komodoensis) are the largest of all lizards. Adult Komodo dragons are dull
brown, dark grey, or reddish in color, while juveniles are green with yellow
and black stripes.
Komodo
dragons are carnivores and scavengers. They are the top carnivores in their
ecosystems. Komodo dragons occasionally capture live prey by hiding in ambush
and then charging their victims, although their primarily food source is
carrion. They have good vision and adequate hearing but rely mostly on their
acute sense of smell to detect potential prey. Komodo dragons have a long,
yellow, deeply-forked tongue and sharp serrated teeth.
Komodo
dragons have a rounded snout, strong limbs, and a muscular tail. They establish
home ranges but they do not defend these territories. When Komodo dragons
encounter one another, the dominant lizard (usually the largest male) prevails.
The mating
season for Komodo dragons takes place each year during July and August. In
September, females dig an egg chamber in which she lays up to 30 eggs. She
covers the eggs with leaves and lies over the nest to incubate the eggs. After
about 8 months they hatch and the mother provides no additional care. When
born, the young are approximately 37cm in length. They are vulnerable to
predation by adult Komodo dragons, birds, and mammals. For this reason the
young climb up into trees where an arboreal lifestyle gives them refuge from
predation until they are large enough to defend themselves.
Habitat:
Komodo dragons inhabit the Indonesian islands of Komodo,
Flores, Rinca, and Padar. They live in tropical savannah forests, open lowland
habitat, beaches, dry riverbeds.
Diet:
Komodo dragons are carnivores. Young Komodo dragons feed on
small prey such as lizards, snakes and small mammals. Adult Komodo dragons prey
on larger animals such as deer, water buffalo and pigs. They also feed on
carrion.
Size and Weight:
6½ - 9¾ long and about 150 pounds
Reproduction:
Komodo dragons reproduce sexually. They reach sexual maturity
at about 5 years of age and breed during the months of July through September.
Their gestation period is 8 months.
Classification:
Komodo dragons belong to the Varanidae, a group of squamates known more commonly as the
monitor lizards.
