There are number of reptiles in the world from Iguanas to Geckos and may include some dragon (not a real one obviously). Lizards have many species
10. Gecko Lizards
These are small reptiles that are generally found in a warm environment. Geckoes have about 1,500 different species. Like most lizards, geckos can lose their tail. Many species are well known for their toe pads that enable them to climb smooth and vertical surfaces. Geckos live in warm regions and can make their home inside human habitations and they are often welcomed as they eat insects, including moths and mosquitos. Geckos produce very little heat like other reptiles.
These reptiles have adhesive toe pads at least most of them. these pads are gained and lost over the time of a geckos evolution. Gecko skin does not generally have bear scales but appears at a macro scale as a papillose surface which is made from hair-like protuberances developed across the entire body. Geckos can replace 100 teeth in the course of 3-4 months. Next to the full-grown teeth, there is a small replacement tooth developing.
9. Armadillo Gridled Lizards
These reptiles are called the Armadillo lizard is also known as the Golden armadillo lizard or The golden spiny-tailed lizard. This species of lizards are endemic to desert areas along the western coast of South Africa. This lizard can be from light to dark brown while the underbelly is yellow with a blackish pattern. its size can be from 7.5 to 9 cm. It can grow to 10.5 cm maximum.
This lizard mostly inhabits rocks, outcrops, and mountain slopes. The diet of this mainly depends on small vertebrates such as insects and spiders but sometimes may contain some plant materials. These lizards live in social groups of 30-60 individuals. female armadillo lizard gives birth to one or two young ones. This species is one of the few lizards that does not lay eggs and the lizards even feed the young ones which is unusual for a lizard.
8. Marine Iguana.
Marine iguanas have the thickset body and they are relatively short with robust limbs. The scales on the top head of the marine iguana are quite conical and pointed. Marine iguanas are not always black; the young have a lighter colored dorsal stripe, and some adult specimens are grey. The marine iguana lacks the ability on land but is a graceful swimmer. These iguanas have a row of the spine along the back provide stability. Its long, strong sharp claws help it to stick to rock during a strong current.
They are unique marine reptiles as they forage relatively in cold water around the Galapagos islands. Which typically are at 11 and 23 c at the sea surface. The temperature declines during the foraging trip to the sea sometimes as much as 10 c. As there preferred body temperature is from 35 to 39 c. At cold temperatures, their muscles are less efficient. A marine iguana can only spend a limited time in the cold waters diving for algae. After that iguana has to come to the surface to basks in sun to gain heat. until then they can’t perform effectively, making them vulnerable to predation.
7. Thorny Devil
The Thorny Devil is also known as the mountain devil, thorny lizard, or thorny dragon. It grows up to 21 cm in total length including tail. With females generally being larger than males. Specimens are generally covered in brown tan color. Body-color of these reptiles can change from being pale in the summer to darker in winters. The thorny devil is covered entirely with conical spines that are mostly uncalcified. They usually live in arid scrubland and desert that covers most of Central Australia.
The Thorny Devil is covered in hard and sharp spines that prevent them to get swollen by a predator. This devil mainly sustains on ants. Eating up to thousands of ants in a day. Absorption through sand is the thorny devil’s main source of water intake and it can collect moisture in the dry desert by condensation of dew.
6. Reticulate Gila Monster
The snout-to-vent length ranges from 26 to 36 cm. The tail is about 20% if the body size and the largest specimen may reach 51 to 56 cm in total length. The Gila monster is found in Southwest United States and Mexico. Gila monsters spend 90% of their lifetime underground in rocky shelters. They are active in the morning during the dry season. Later after summer they are active on warm nights or after a thunderstorm. They are usually preyed upon coyotes, badgers or raptors. on top hatchlings have to fear adult snakes such as king snake.
The diet of Gila monster consist of variety of food items young Rabbits, Mice, Ground squirrels or other rodents. The Gila monster produces venom in modified salivary glands at the end of its lower jaw. The venom of Gila monster is considered to be as toxic as that of a Western diamondback rattlesnake. But it’s bite is not normally harmful for adult size humans. Though gila monsters can bite quickly.
5. Komodo Dragons
Komodo dragon also known as the Komodo monitor is a species of lizards found in Indonesia island Komodo, Rinca, Flores, and Gili Motang. This species can grow to a maximum length of 10 ft. in rare cases and weighing approximately 70 kilograms. This factor makes them dominate the ecosystem in which they live. Komodo Dragon hunting behavior in the group is exceptional in the reptile world. The dragon is dangerous as they hunt in packs.
Komodo dragons generally prefer hot and dry places and typically live in dry and open grassland, savanna, or tropical elevations at low elevations. They are capable of running at the speed of 20km/h and can also climb trees with the help of their strong claws. Komodo dragons stand on their hind legs with the support of its tail to catch out of reach prey. Its claws are used primarily as weapons.
Chameleon comes in a range of colors and has many special abilities. A chameleon varies greatly in size and body structure. Many have facial or head orientation such as horn-like projections. Some chameleon species are able to change their skin coloration. Chameleon skin has a superficial layer that contains pigments and under that layer, there are guanine crystals. They change color by changing the spaces between guanine crystals. This changes the wavelength of light reflected off the crystals which changes the color of the skin.
All chameleons are primarily insectivores that feed by ballistically projecting their long tongues from their mouths to capture prey located some distance away. While the chameleons’ tongues are typically thought to be one and a half to two times the length of their bodies (their length excluding the tail), smaller chameleons (both smaller species and smaller individuals of the same species) have recently been found to have proportionately larger tongue apparatuses than their larger counterparts.
3. Flying Geckos
They are commonly known as flying geckos, Gliding geckos or parachute geckos. The center of diversity of which is within Southeast Asia. Since dispersing into Southeast Asian rainforests. Just like other forest dwelling vertebrates adapted to facilitate gliding.
When the gecko leaps into the air, the flaps are used to generate lift and allow the gecko to control its fall. It can glide up to 200 feet (60 meters). Also it does a swoop at the end of its glide to land softly. A similar adaptation is found in geckos of the genus Cosymbotus
2. Rock Agamas
This is a small-medium sized lizard with a long tail, an insectivorous old-world lizard. The color differs between species, genders, and according to mood. A dominant male in display mode is far brighter than when it has been caught. Females tend to be less colorful than the male of the species. Agamas live in the forest, in the bush, among rocks, and on crags. They can tolerate higher temperatures than most reptiles, but when temperature approach around 38 c they approach for shelter.
Agamas are active during the day as they can handle high temperature. Males threaten each other by nodding, weaving, and displaying their brightest colours to establish dominance. The jaws are very powerful, and older mails generally have damaged tails due to past combats. Females may chase and fight one another. Hatchlings may mimic the adults behaviour. Dominant males commonly accommodate several females at a time in their territory. This is a way of asserting dominance over others.
1. Rhinoceros Iguanas
Rhinoceros Iguana is an endangered species of iguana that is most commonly found in the Caribbean island of Hispaniola, They vary from 60 to 136 centimeters. The skin colors range from steely grey to dark green and sometimes brown. Rhinoceros iguana is a heavy-headed lizard with strong legs and vertically flattened tail. they weigh from 4.56 to 9 kilograms. They usually aggressively attack by biting and repeatedly striking with their thick tail. These are Herbivorous, unlike other lizards. Consuming fruits, leaves, flowers, and berries.
Their name derives from the bony-plated pseudo-horn or outgrowth which resembles the horn of a rhinoceros on the iguana’s snout. The horns along the lateral spines and prominent bulges, function as protective armor against sharp rocks or as defensive tools. It helps to facilitate the escapes of males from the grasp of one another.
