Tucson, it’s time to meet The King of the Lizards!
The Reid Park Zoo’s expansion will be bringing us the biggest lizard on earth – the Komodo Dragon. These real-life fairytale creatures are huge, they’re fascinating, they’re apex predators, and they’ve been around for 100 million years or so. And though they have no natural enemies, they’re now vulnerable in the wild.
They’re Huge. And Hungry.
These giants average about 10 feet long and 154 pounds for males, and the largest Komodo Dragon on record was 10.3 feet long and weighed 366 pounds. And they’re incredibly strong, especially in the muscular jaw and neck area. They are such efficient eaters that they can eat up 80% of their own body weight in just one day. Luckily, their stomachs can expand. And they have another useful trick for that sluggish feeling you get after overeating. If they sense a threat and need to flee quickly, they simply throw up their stomach contents and lose the extra weight.
What about that fearsome bite?
The Komodo Dragon is an ambush predator, lurking patiently by the side of known wildlife paths to conserve energy, then leaping and striking when a tantalizing animal passes by. Its favorite meal in the wild is the Timor Deer, but it will eat anything from large water buffalo to its own newly-hatched offspring. That’s why the newly-hatched Komodo Dragon young scramble immediately up trees so the adults can’t get to them! And they don’t come down for several years, until they’re four feet long.
The Dragons’ teeth are large, they’re sharp, and they’re serrated. They’re also breeding grounds for bacteria, since their particular brand of oral hygiene, leaving scraps of their previous meals on and between their choppers, encourages the development of around 50 different bacterial strains. Seven of these are highly septic and thrive in the dragons’ saliva. As if that weren’t enough, researchers have also located a venom gland in the lower jaw, and that venom happens to be an anticoagulant. The effects of a dragon bite are generally profuse bleeding and the onset of sepsis. The victim will often flee, but after a few days, will surely succumb to the attack.
The Daily life of an adult Komodo Dragon
The Dragons are indigenous to five islands in Indonesia, four in Komodo National Park (Komodo, Rinca, Gili Montang, and Gili Dasami) and another island outside the park, called Flores.
The mostly solitary life of adult Komodo Dragons consists of four things: hunting, eating, basking in the sun (they’re ectothermic), and lots and lots of sleeping. Most of these require very little energy, and researchers have discovered that even though these reptiles are capable of travelling long distances, they almost never stray from the areas where they and their progenitors have always lived.
Their survival is now threatened
Their numbers in the wild are decreasing, largely through human encroachment, habitat fragmentation, the illegal wildlife trade, tourism and its damage to the ecosystem, and the burning of grasslands in order for humans to hunt the Dragons’ favorite prey, the Timor Deer.
The research and breeding of Komodo Dragons that can be safely done in human care is now more important than ever. The Reid Park Zoo hopes you’ll come see this most amazing lizard once the Pathway to Asia expansion is complete! Just by visiting, you’ll be helping the Zoo in their efforts to conserve these ancient and fascinating creatures.
