A marine iguana removes salt from its body through salt glands located in the cranial cavity. These glands connect to the marine iguana's nasal cavity, allowing for expulsion when the marine iguana blows forcefully.
A bearded dragon bobs its head when trying to exert dominance over another bearded dragon. Bobbing the head also signals that a male dragon wishes to mate with a female.
The lifespan of a bearded dragon is six to 15 years. Australia is their natural habitat; however, they can be found around the world as pets.
Komodo dragons are the top predators in their range, and adults do not suffer predation by any species. Young Komodo dragons sometimes fall prey to predatory mammals, birds and other Komodo dragons. Juveniles live in trees as protection until they are large enough to defend themselves.
Green anoles lay eggs. They willingly mate in captivity, and most females lay viable eggs. The real challenge is keeping the babies alive until they are able to fend for themselves.
Bearded dragons are omnivores and eat a variety of plant and animal matter. Pet bearded dragons also eat prepared bearded dragon food, which often comes in pellet or freeze-dried varieties.
A group of lizards is called a lounge. Only about 20 out of 6,000 lizards live in groups. Most lizard species are oviparous, meaning they lay their eggs. Many lizards lay their eggs in a secluded, thermally stable location, and then bury the eggs and leave them forever.
Leopard geckos are desert-dwelling reptiles native to parts of southern Asia. Leopard geckos are among the larger gecko species and, unlike many gecko species, they possess eyelids and lack adhesive structures on their feet.
National Geographic reports that wild geckos usually eat insects, but some species may also occasionally consume fruit and flower nectar. About.com states that leopard geckos are the species of gecko most commonly kept in captivity. They should be fed crickets, waxworms and mealworms, and the insects should be coated with a calcium-vitamin D3 supplement before feeding consumption.
Green Iguanas may grow to be 6 feet long and require habitats large enough to move around in. They are comfortable at temperatures in the range of 85 degrees. Green Iguanas are herbivores and subsist on plants, fruits and vegetables. They require a great deal of UVB light, that must be supplied to them for at least 12 hours each day. Do not house two or more iguanas together.
Lizards pass through three different life stages, beginning as eggs, hatching into juveniles and ultimately becoming mature adults. Most juveniles resemble miniature versions of the adults, while others experience a change in color or body proportions as they grow. Some lizards pass through all three life stages within the course of one year, while others live long lives, taking many years to hatch and mature into adults.
The lizard has a wide variety of predators, including birds, snakes and even other lizards. When being chased or attacked by predators, lizards may swell up, hiss, break off their tails to escape or even change colors to blend in with their surroundings.
Different types of geckos can be identified by their size, coloration, patterns and markings, and their native habitat. Other forms of identification are whether the gecko can change its color, its temperament and if its toes have adhesive pads.
Geckos live on every continent except for Antarctica. They are mostly found in warm climates and live in numerous habitats, such as rain forests, deserts and even on cold mountain slopes.
Depending on the species, it can take anywhere from several weeks to several months for a lizard egg to hatch. For pet lizards, such as Anoles, eggs should hatch at around the 4 to 6 week mark, whereas the eggs of larger, wild lizards, such as Komodo Dragons, can take 7 to 8 months to hatch.
Most species of lizard are quadrupedal and crawl using their four limbs and tail. Certain species are legless and slither like snakes. Some lizards, such as geckos, can adhere to vertical or inverted surfaces and move freely on them.
The diet of baby lizards varies from one species to the next, but most young lizards eat insects or other invertebrates. Crickets, roaches, earthworms, mealworms and silkworms are all acceptable items, but spiders, wasps, ants and other offensive species are not appropriate food items. In addition to providing a baby lizard with the appropriate prey species, be sure to provide prey of the appropriate size.
The lifespan of most lizard species varies from 1 to 20 years in length. The lizard species and whether or not it lives in captivity, is the reason for the variance in life expectancy. There are more than 3,800 species of lizards.
It takes a month to a year for a lizard's tail to grow back. Lost tails are only regrown up to three times. A lizard sheds its tail once a defense mechanism to elude a predator is set in motion.
Geckos eat a variety of food items, including insects, arachnids, mollusks, small vertebrates and other small animals. Additionally, some geckos consume fruits and flower nectar. There are approximately 1,500 gecko species in the world, and the group displays a wide variety of dietary preferences.
It is acceptable to feed bearded dragons broccoli because the bulk of their diet consists of leafy vegetables, non-citrus fruits and occasional insects. An excessive amount of broccoli can be harmful to the bearded dragon, however, so it is best to feed the bearded dragon uncooked broccoli only occasionally.
