k is for Komodo Dragon
Komodo dragons live on a few Indonesian Islands, including the one that gives them their name.
They are extremely large, aggressive lizards, growing up to 10 feet long. New research suggests that contrary to former opinion, that they grew so large because there was no competition on their isolated islands, they are actually relics of giant lizards that died out after the Pleistocene period.
Komodo dragons are carnivores and eat mainly deer, sometimes buffalo and anything else in their way, including their own young, who retreat up trees to keep out of the way. They will attack humans on occasion, although they usually avoid them. Carrion is also consumed.
Komodos cooperate in killing large prey, which is unusual in reptiles – but a single komodo can also kill a buffalo – one bite from their mouth is usually fatal.
Not only do their mouths contain an enormous number of virulent bacteria, but they also have a venom that is discharged with the bite. The venom sacks lie in the lower jaw. Scientists are still arguing about exactly how the prey is brought to death – blood loss and shock are other factors that play a part.
Whatever the means – the prey does fall eventually, and the komodo can follow the scent of the dying prey which it tastes in the air with its tongue.
Dead animals are ripped apart with strong slicing motions of the mouth and the prey is soon eviscerated and gulped in huge chunks – even the skull. The lizard pushes the prey into its mouth sometimes by using a tree to bash it in with – even knocking trees over.
Komodo dragons are listed as vulnerable and there are under 7,000 of them left on the islands.
