Dragon lizards also called Agamids, are some of the most distributed lizard species in this planet. You usually find them in warm environments of Southern Europe, Australia, Asia and Africa. With 300 types in the species, their size ranges from five inches to one foot. You can find them in an array of colors, and they feed on eggs of smaller lizards, seeds, berries, grass and insects. The popular lizards among them are the frill-necked lizard and the Rainbow Agama. Interestingly, the males in a few species of Agamids, evolve attractive body colors in the breeding season, and this has an effect on reproductive behavior and communication.
Some of the well known dragon lizards
Draco Volans, or the Flying Dragon, is a member of the genus of gliding lizards Draco. It can spread out folds of skin attached to its movable ribs to form “wings” that it uses to glide from tree to tree over distances upwards of 8 meters (25 feet); however, like all modern reptiles, it lacks the ability to sustain powered flight, and is capable only of gliding. Its wings are brightly colored with orange, red and blue spots and stripes, and they provide camouflage when folded. The flying dragon can reach lengths as long as 19 – 23 cm. It feeds on arboreal ants and termites.
The Komodo Dragon (Largest dragon Lizard)
The largest of living dragon lizards is the Komodo dragon, a kind of monitor lizard. The ancestral history of the monitor lizard goes back to more than 100 million years. Western scientists did not know about the Komodo dragon until 1912. The name Komodo dragon came from the rumors about a huge dragon-like lizard in the Lesser Sunda Islands, The Komodo dragon’s forked and yellow color can easily remind us of the legendary dragons that spit fire in folk tales of yore.
The color of the Komodo dragons ranges from yellow to gray, which depends on their location. They have rough, tough skin with bony plates called osteoderms strengthening the skin. These also protect them injuries from bites and scratches. The tail is long and muscular. They have powerful claws. The Komodo dragon can grow up to 3 meters and can weigh up to 135kgs.
The Komodo dragon has a leisurely lifestyle. It comes out of its burrow and selects a sunny spot to warm up. After finding breakfast, it enjoys a long nice nap in a shady spot during the hotter parts of the day. After enjoying a late afternoon meal, the dragon gets ready to sleep till the next day. It is a lonely creature that prefers to live and hunt alone.
You can find the Komodo dragons only on five islands in southeastern Indonesia. Four of these islands are within the Komodo National park. They are Komodo, Rinca, Gili Montang and Gili Dasami Islands. The fifth is the island of Flores. These volcanic islands have a rugged and hilly terrain, covered with forest or Savanna type grasslands.

They mainly inhabit the Southern, Western and Southern part of the Northern Territory of Australia.
As a Pet
We must shape and size the habitat to accommodate their normal behavior and exercise. These lizards have varied growth rate and sizes. Their individualized needs also vary. You must consult a qualified veterinarian or a book on this species to find out their specific housing needs. Do not try to keep the large dragons like the Komodo that you better leave for the wild or to highly equipped zoos.For those dragons that you can handle, you must provide a hiding area and branches for basking. You can maintain less than 50% humidity by misting when needed. The substrate can be calcium based sand. The lizards may swallow Silica- based sand and create impaction. You can use Repti carpet substrate as another option. The temperature gradient can be 100.F for the warm end and 70.F for the cool end. You can provide radiant heat.
Food items should not be more than 1/3rd of the size of the lizard’s head. This is to ensure that the young once can swallow these safely. The lizards can eat small insects like meal worms, earthworms and crickets. We must necessarily use commercially branded dragon food. Food items can be larger when they grow up. You should spray water on them every day and continue this until they stop sipping the water.
You can easily determine the sex of these dragons by observing them even when they are a few months old. The males are more violent in behavior and more aggressive eaters. When these dragons are 5-6 months old, we can find out the sex by looking at the bulges of the hemipenes in the males. We can do this by observing several juveniles. The males develop a dark head and have wider heads as secondary sex characteristics. Males do the head bobbing to display their territory, but arm- waving can be done by both the sexes.
Dragon lizards tolerate interaction with humans. They will spend part of the day in a hiding spot in their habitat.
