Komodo Dragons - Indonesia

This week i haven't received any unesco cards yet but i still have tomorrow. This indonesian card was the last unesco card i got. It was sent by Shinta and it shows Komodo dragons in the Komodo National Park, a Unesco World Heritage Site since 1991.
"The Komodo dragon is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores and Gili Motang. A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to an average length of 2 to 3 metres (6.6 to 9.8 ft) and weighing around 70 kilograms (150 lb). Their unusual size has been attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live.However, recent research suggests that the large size of komodo dragons may be better understood as representative of a relic population of very large varanid lizards that once lived across Indonesia and Australia, most of which, along with other megafauna, died out after contact with modern humans.
As a result of their size, these lizards dominate the ecosystems in which they live. Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds and mammals.

Mating begins between May and August, and the eggs are laid in September. About twenty eggs are deposited in abandoned megapode nests and incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and cannibalistic adults. They take around three to five years to mature, and may live as long as fifty years. They are among the rare vertebrates capable of parthenogenesis, in which females may lay viable eggs if males are absent, producing only female offspring.
Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In the wild their range has contracted due to human activities. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts." - in: wikipedia
