Monitor Lizard Biography and Facts

Biography of Monitor Lizard

Monitor Lizards are large reptiles found in Africa and all across Asia, including the surrounding seas. This lizard is mainly found in jungle areas although some species of monitor lizard are water-bound. Some species are thought to carry a fairly weak venom, for example, the komodo dragon which is the largest of the species. The komodo dragon is native to the small Indonesian island that it is named after and is the largest species of lizard in the world.

According to legend, monitor lizards were a sign that there were crocodiles close by, possibly due to their standing on their hind legs to monitor their surroundings. Monitor lizards do this so that they are aware of any approaching predators. Although many species are quite big, some species are smaller than 20 cm in length. Monitor lizards are extremely versatile animals and monitor lizards adapt well into different environments.

Facts about Monitor Lizards

Most species of monitor lizard have a predominantly carnivorous diet, eating eggs, smaller reptiles, fish, birds and small mammals. Some species of monitor lizard also eat fruit and vegetation depending on where they live. Female monitor lizards bury their eggs in holes or hollow tree stumps that the female monitor lizard then covers with dirt in order to protect her eggs. These lizards can lay up to 30 eggs at a time, although many lizards lay less, and only a lucky few of the monitor lizard babies tend to survive.

Monitor lizards are thought to be fairly intelligent animals, with some people claiming that are able to recognise numbers up to six, therefore meaning that lizards are able to count! Monitor lizards mainly use their intelligence in the wild by surveying areas for oncoming danger and for hunting their prey.

Leopard Tortoise

The leopard tortoise is a large species of tortoise found throughout the African savannas. The leopard tortoise is the forth largest species of tortoise in the world, and is also the most widely distributed tortoise species in Southern Africa. The leopard tortoise has a wide distribution in sub-Saharan Africa from Sudan to the Cape. As a grazing species of tortoise, the leopard tortoise is most commonly found in semi-arid areas including shrubland and grasslands.

The leopard tortoise is one of the world's largest tortoise species as they can grow to 70 cm in length and weigh about as much as a small person. As with other tortoise species, the leopard tortoise has a large shell which protects it's softer body. The limbs of the leopard tortoise are able to retract back into the leopard tortoise's shell so that no body part is left vulnerable. The leopard tortoise is a generally solitary animal that spends the majority of it's time grazing on plants, which it can do effectively using it's sharp beak-like mouth. As with other tortoise species, the leopard tortoise is a long-lived animal species, often reaching 100 years old or even more.

The leopard tortoise is a herbivorous animal meaning that it only eats plants and plant material in order to sustain itself. The leopard tortoise primarily grazes on grasses, leaves, berries and flowers along with fruits such as the prickly pear. Due to it's fairly large size, the leopard tortoise has few natural predators within it's African habitats as many simply cannot penetrate the leopard tortoise's high-domed shell. Humans are the primary predators of the leopard tortoise along with the occasional wild cats and dogs.

Leopard tortoises are not able to reproduce until they are at least 10 years old (known as reaching sexual maturity). As with other tortoise and even reptile species, the female leopard tortoise lays her clutch of up to 18 eggs into a burrow in the ground, which is quickly covered to protect her young from hungry passers-by. Although there are thriving populations of leopard tortoises in more remote areas, when they are close to humans, the leopard tortoise populations are generally suffering, something which is primarily due to over-hunting by humans.

Komodo Dragon

The komodo dragon also known as the giant monitor lizard, is the largest species of lizard in the world.The komodo dragon inhabits the rainforests of Southeast Asia, and the komodo dragon is native to just a few islands in Indonesia that are part of the Komodo Island National Park. Fossil evidence however, suggests that the komodo dragon once had a much larger habitat but this has been severely decreased due to deforestation. Komodo dragons are completely dominant predators in their environment, and are named by the locals as the land crocodile due to their large size and habit of eating seemingly anything that the komodo dragons can find.

The komodo dragon has an exceptional sense of smell meaning that the komodo dragon is able to hunt out its prey up to 8 km away, when aided by the wind blowing in the right direction. Recent discoveries have revealed that the komodo dragon is indeed venomous, and does not kill its prey through lethal bacteria, as previously thought. However, once the damage the komodo dragon can do coupled with the fact that the saliva of the komodo dragon is known to carry more than 50 different strains of bacteria, means that any animal that manages to survive the attack of a komodo dragon, is extremely likely to die of infection.

The komodo dragon hunts anything that comes into contact with the komodo dragon, including its own eggs! Generally komodo dragons are not known to actively hunt humans, but the komodo dragon is known to be one of the man-eating animals in the world, as it is not uncommon for the komodo dragon to attack and eat humans that get in its way. To hunt their prey, komodo dragons rely heavily on their camouflage in the long grass and great patience as the komodo dragons sit and wait for prospective prey to pass.

Due to the fact that the komodo dragon is an apex predator in its limited environment, the komodo dragon will often live to more than 30 years of age. The main exception to this is the side effects that occur due to deforestation and areas where there is a lack of food for the komodo dragon to hunt. Today there are thought to be around 3,000 komodo dragon individuals left in the wild with less than a third of them being female komodo dragons that are of the age to breed. Source

Water Dragon

The water dragon is a large species of lizard native to the forests and jungles of Asia and Australia. Water dragons are arboreal animals meaning that they spend most of their time in the trees, often close to a large body of water. There are two different species of water dragon, which are the Australian water dragon and the Asian water dragon. The Australian water dragon is the smaller of the two water dragon species and is found on the east coast of Australia. Australian water dragons have powerful legs and sharp claws which help them to climb trees more effectively.

The Asian water dragon is the larger and more colourful of the two water dragon species and is found in forests and jungles throughout India, China, Laos, Vietnam, Burma and Thailand. The Asian water dragon also has a third eye (known as the pineal gland), which is thought to be able to detect difference in light. Although water dragons are generally tree-dwelling animals, they also spend a great deal of time in or very close to the water.

Like many other lizard species, water dragons are omnivorous animals eating a variety of plant and animal species. Water dragons primarily prey upon small animals such as lizards, frogs and rodents, insects and fish which they catch will there long tongue. Due to their relatively large size, water dragons have limited predators within their natural environment, although this is entirely dependent on where the area which the water dragon inhabits. Snakes, large birds and carnivorous mammals are the primary predators of the water dragon.

Water dragons hibernate during the cooler winters and begin breeding when they emerge in the spring. The female water dragon digs a burrow in the ground where she lays up to 18 eggs, and then buries them. The water dragon young hatch within a few months and remain close to the nest until they become bigger and more adventurous. Source

Pancake Tortoise

Pancake tortoises are small and flat with a thin, flexible shell. The shell is normally 6 to 7 inches long and an inch or so high. On the legs, they have bigger scales with points that project downward and outward. Usually the shell has radiating dark lines on the carapace (upper part of the shell). The plastron (bottom part of shell) is also pale yellow but with dark brown seams and light yellow rays. Juveniles have pale yellow top shells with black seams and yellow rays. Some may have brown spots on their back.
 

The carapace of juveniles is more domed than that of adults. Males can be distinguished from females by their larger and longer tails. However they are smaller than the females and have less distinctive patterns on their shell. The pancake tortoise is adapted to fitting into tight crevices. Even larger individuals are less than 2 inches high. The shell is so thin and flexible that the plastron moves in and out when the animal breathes. Since the tortoise ould easily be torn apart by predators, it relies on its speed and flexibility to escape from dangerous situations.

With the reduced weight of the shell, it can move much more quickly than other species. It was once thought that it could puff its body up with air to wedge itself in place, but this has been found not to be true. Instead, it orients its spiky legs outward so that it is almost impossible to dislodge. Also this animal can also climb vertically. Because they are so light they can turn themselves over with ease if they fall on their backs.

In the wild breeding is in January-February with nesting in July-August.They lay eggs that are about two inches long. The eggs can incubated at about 30 degrees Celsius for 140 to 190 days. Combat between males prior to breeding can lead to better reproductive success.  In captivity breeding can be any time of the year. Captive animals can live 25 years and perhaps longer. Source

Painted Batagur

The Painted Batagur is the largest turtle living in fresh water. They are in danger of extinction because people take them as pets or to eat, and because of the deteriorating environments in and around the rivers they live in. Painted Batagurs live on the Malaysian peninsula, Sumatra Island, and Kalimantan Island. Painted Batagurs live in rivers and sometimes go near the ocean where the seawater mixes with the fresh water. They also lay eggs in sandy beaches like Green Turtles.

Additionally, there are efforts to increase their number by breeding. Although there are international restrictions against the sale and purchase of Painted Batagurs, there are still many efforts that need to be made to recover their numbers, such as making river environments safe for living in. The painted terrapin is critically endangered species according IUCN, listed in The World's Most 25 Endangered Freshwater Turtles and Tortoises 2011.

It is listed in Appendix II, with a zero quota for commercial trade of wild-captured specimens according to the CITES meeting in Thailand, March 2013. Batagur borneoensis is a priority species to be conserved in Indonesia according Minister of Forestry Decree No. 57 Year 2008 about Strategic Direction of National Species Conservation 2008-18. In Malaysia, this species is also protected.

Harvesting by fishermen to eat, poaching to meet pet and food demand, habitat loss due to land conversion to palm oil, and fish and shrimp farming are major threats. Conservation efforts in Sumatra, Indonesia, are ongoing to increase wild populations by carrying out nesting patrols to secure and hatch the eggs, for later release into original habitats. Source

Box Turtle

The box turtle or box tortoise is a genus of turtle native to North America. Box turtles are land dwelling creatures with high, domed shells, hence the "box" moniker.  Box turtles are found all over the world, and are generally found living in mossy areas of the forest, or other damp habitats.  They are very territorial, and sometimes spend their entire lives near their place of birth.

North American box turtles are omnivores with a very varied diet as box turtles "basically eat anything it can catch". Invertebrates (amongst others insects, earth worms, millipedes) form the principal component, but the diet also consists for a large part (reports range from 30-90%) of vegetation. The diet is amended with fruits (amongst others from cacti, apples and several species of berry), gastropods.

While reports exist that during their first five to six years, box turtles are primarily carnivorous, while adults are mostly herbivorous, there is no scientific basis for such a difference. They are strong, sturdy animals, and usually grow to be about 6 inches long.  Box turtles are usually dark in coloring with some yellowish markings, and the male of the species have bright red eyes, longer tails, and their plastrons are indented.

Box turtles are endemic to North America. The widest distributed species is the common box turtle which is found in the United States (subspecies carolina, major, bauri, triunguis; South-Central, Eastern and South Eastern parts) and Mexico (subspecies yukatana and mexicana; Yucatán peninsula and North Eastern parts). The Ornate box turtle is endemic to the south-central and South Western parts of the U.S.  while the spotted box turtle is endemic to North-Western Mexico only. Source

Egyptian Tortoise

The Egyptian Tortoise is the smallest land turtle in the Northern Hemisphere. The Egyptian Tortoise is a critically endangeredneck-hiding tortoise. Once more widespread, its numbers are now dwindling. The species is extinct in Egypt, and global extinction is a looming threat unless more actions are taken to protect this species. They are on the brink of extinction due of habitat loss and because people capture them to make pets.

Once found in Egypt and Libya, their habitat in Egypt has been all but destroyed, and Egyptian tortoises are close to complete extinction there. Two populations can still be found in Libya, but much of the coastline habitat has been destroyed because of human activity. Habitat loss and the illegal pet trade are huge issues facing the species; it is also hunted locally for use in folk medicine.

The Egyptian tortoises are herbivores, feeding on rough grasses, desert plants and fruit. They are most active during the warm periods of the year and least active during the months when it is very cold or very hot. During the cooler months, the tortoise is most active at midday. In the hot months, it is only active during the early morning or late afternoon and spends the rest of the day hiding in the cover of bushes or in rodent burrows.

Another unfortunate reality is the loss of habitat. Much of what used to be habitat for the Egyptian Tortoises has now become farmland or towns. Moreover, any remaining grassland has become a pasture for domestic livestock where many goats and sheep feed on the vegetation that used to be the tortoises' food. Many countries are cooperating to protect the Egyptian Tortoise, but many still believe their population will continue to drop further. Source
