Liger

Natural Wild Life | Liger |  The liger is a hybrid cross between a male lion (Panthera leo) and a tigress (Panthera tigris). Thus, it has parents with the same genus but of different species. This combination produces an offspring with more lionistic features than if the reverse pairing had occurred. That would produce a more tigeristic creature known as a tigon. Both are members of genus Panthera.There is no scientific name assigned to this animal because it is a combination of two species. Some ligers grow impressive manes, while others do not. Ligers are prone to giantism and grow much larger than either parent. A liger looks like a giant lion with muted stripes but like their tiger ancestors, ligers like swimming.

Swimming goes against the nature of a lion but is what makes hybrid creature special. It gets the best of both parents. That is not always the case though with crossbreeds. Sometimes the results go the other way and the animal gets the worst of both parents. A tigon or tigron is a hybrid cross between a male tiger and a female lion or lioness. The tigon is not currently as common as the liger, however, in the late 19th and early 20th centuries, tigons were more common than ligers. Tigons tend to be the same size or smaller than their parents and have less angular heads. They have a stronger striping pattern generally.

As the liger is the offspring of two different animal species, the lion and the tiger, the liger is thought to be sterile in the same way as a mule or zonkey. However, the male ligers and tigons are sterile while the female ligers and tigons are generally fertile. The males typically have low testosterone and not very motile sperm. Because only female ligers and tigons are fertile, ligers and tigons cannot reproduce with each other. They can breed to a male of either parent species (tiger or lion) producing 3/4 tigers and 3/4 lions (ti tigon, ti liger, etc).

Tortoise

Natural Wild Life | Tortoise | The tortoise (Testudinidae) is a family of land-dwelling reptiles of the order of turtles (Testudines). The tortoises closely related to the tortoise's marine cousin, the sea turtle. The tortoise is found in many countries around the world but particularly in the southern hemisphere where the weather is warmer for most of the year. Tortoises have a hard outer shell to protect them from predators but the skin on the legs, head and belly of the tortoise is quite soft so the tortoise is able to retract it's limbs into it's shell to protect itself. The tortoise's shell can range in size from a few centimetres to a couple of metres, depending on the species of tortoise.

Most species of tortoise have a herbivorous diet eating grasses, weeds, flowers, leafy greens and fruits.Tortoises generally have a lifespan similar to the lifespan of humans although some species of tortoise, like the giant tortoise, have known to be over 150 years old. There are many different species of tortoise around the world that vary in size, colour and diet. Most species of tortoise however are diurnal but in places where it is very hot throughout the day, tortoises will often venture out to find food in the cooler dawn and dusk periods.

Female tortoises dig burrows, known as nesting burrows, in which the female tortoise lays her eggs. The female tortoise can lay between one and thirty eggs at a time but the number is generally around 10 and only a handful of the babies tend to survive as tortoise babies are very vulnerable to attack by all kinds of predators. Once the female tortoise has laid her eggs she leaves the nesting burrow. The eggs hatch between 2 and 4 months later and the baby tortoises are able to start venturing out in search of food when they are about a week old. The size of the baby tortoise and the egg, depends on the size of the mother tortoise.

Today, a number of tortoise species (mainly the smaller species of tortoise) are kept as household pets. The pet tortoise ideally prefers to live in the garden or part of a vegetable patch where there is lots of food for the tortoise to eat. Pet tortoises should have a diet similar to what it would be if the tortoise was in the wild and should not be fed other foods such as cat or dog food. Most species of tortoise, but not all, hibernate during the colder winter months particularly those species of tortoise in the Northern Hemisphere. Tortoises must have an empty stomach before they hibernate and therefore tend to go through a period of starvation beforehand. Tortoises come out of hibernation when the weather begins to get warmer again.

Markhor

Natural Wild Life | Markhor | The Markhor (Capra falconeri) is a large species of wild goat. The markhor is an endangered species of wild goat that is natively found in the mountainous regions of western and central and Asia. The markhor is thought to have been named using the Persian word for snake, either because of the large coiled horns of the markhor or due to it's ability to kill snakes in the wild, although the exact reason is unknown. The markhor is found in northeastern Afghanistan, Gilgit-Baltistan, Hunza-Nagar Valley, northern and central Pakistan and the disputed territory of Kashmir, southern Tajikistan and southern Uzbekistan. The markhor is most commonly found inhabiting the high-altitude monsoon forests that litter these areas.

The markhor is a very distinctive species of wild goat, easily identified by it's long, white winter hair and the enormous spiralled horns that can grow to more than 1.5 meters in length on the males. The horns of the females are, although still large for goats, generally less than 50cm in length. Markhor are well adapted to mountainous terrain, and can be found between 600-3,600 meters in elevation. They typically inhabit scrub forests made up primarily of oaks , pines, and junipers where there is plenty for the markhor to eat. Markhor are also diurnal animals, meaning that they are mainly active in the early morning and late afternoon.

The markhor is a herbivorous animal that primarily grazes on a variety of vegetation including grasses, leaves, herbs, fruits and flowers. Like other wild goats, the markhor play a valuable role within their eco-system as they munch the leaves from the low-lying trees and scrub, spreading the seeds in their dung. Despite living almost on a cliff-edge, there are actually a number of animals that prey on these incredibly majestic creatures. Packs of wolves and wild cats such as lynxes snow leopards are the main predators of the markhor, along with humans who have deforested much of their natural habitat.

The markhor breeds in the winter when, after a gestation period that lasts for up to 170 days, usually one and occasionally two markhor babies (known as kids) are born. The markhor kids remain safe and looked after by their mother until they are able to eat solid food and become more and more independent. Today, despite being the national animal of Pakistan, the markhor is considered to be an endangered species with less than 2,500 individuals thought to be left in a few remote areas of the Asian mountains. The decline in markhor population numbers in mainly due to deforestation resulting in the loss of their native habitats.

Babirusa

Natural Wild Life | Babirusa | The babirusas are a genus. The Babirusa (Babyrousa babyrussa) is a very special member of the pig family. Up until now the relationship between the Babirusa and the other pig species hasn't been resolved completely. There are pieces of research, which suggest the conclusion, that it is closely related to Hippopotamuses, close relatives of pigs themselves. The babirusa is a very strange looking member of the pig family. They are only distantly related to other pigs, and have been given their own subfamily, the Babirousinae. There are three subspecies of the Babirusa corresponding to the areas where they are found; the Sulawesi, Togian, and Moluccan babirusa. These subspecies have different hair covering, hair color, and tusk and body sizes. Fossil studies seem to show that the babirusa may be more closely related to hippopotamuses than pigs.

The name babirusa in Malay means "pig-deer". It got this name from its bizarre tusks. The upper canines actually grow up through the skin of it snout from the inside. These 12 inch long tusks then grow up and curl over towards the forehead, sometimes touching the snout again. The lower canines are also very long and protrude from the sides. The two sets of tusks give the appearance of the antlers of a deer. Only the bottom tusks are used offensively. The top tusks can't be used for foraging or as weapons because they are very fragile and lose in their sockets. Females have shorter tusks, or none at all. Babirusa are smaller than domestic pigs. They are 2.8-3.6 feet in length, and 2.1-2.6 feet at shoulder height. The tail is 8-12 inches long and not twisted. Babirusas weigh from 95-220 pounds. This curly-tusked pig has a rounded body with almost hairless, bristly skin. The sparse hairs are yellowish in color. Their skin is gray to brown, with a lighter colored underbelly. Their legs are thin and longer than on most pigs. Mature babirusas have large folds near their necks and bellies. Babirusa reach sexual maturity from 1 to 2 years. After mating the pregnancey lasts 150 to 157 days. The babirusa only gives birth to 1 to 3 young at a time, unlike other pigs who will have 7 to 9 piglets. The mother babirusa will lie down to nurse her piglets. Although the young will begin to forage within the first week after birth, they aren't weaned until they are 6 to 8 months old. The babirusa has a life span of 24 years.

The babirusa is usually a solitary animal, although it will sometimes live in small groups. Its habits are duirnal, and it tends to feed in the morning. Its diet consists of fruits, nuts, mangos, mushrooms, leaves, and insects found in rotting wood. Unlike other pigs it doesn't root around the dirt for food with its snout. It moves along well-worn trails along the rainforest floor within their territories. It is a fast runner and a good swimmer, and has been seen swimming to off-shore islands. It has a good sense of smell and makes grunting and moaning sounds. When it gets excited it chatters its teeth. Like most other pigs it loves to wallow in mud baths to rid itself of parasites. In the past babirusa were kept by rulers in Sulawesi and given as gifts to visiting diplomats. Masks of Balinese demons often resemble the stangely tusked babirusa. Unfortunately the future doesn't look good for this amazing creature. They have always been scarce, but are an endangered species today. Although the babirusa avoids farmlands, and isn't persucuted by farmers, it is a favorite target for poachers. Their limited and small pockets of rainforests are also being converted into agriculture. Their wild population is estimated at around 4,000 to 5,000 animals. The IUCN put them on their vulnerable list in 1996, and the U.S. ESA considers them endangered They are on CITES Appendix I.

Vulture

 

Natural Wild Life | Vulture | Vulture is the name given to two groups of convergently evolved scavenging birds. The vulture is a large, carnivorous bird that is most well known for its scavenging nature. The vulture is one of the few types of bird that is found distributed so widely around the world, as vultures are found on every continent excluding the Antarctic and Australia and the islands that surround it. Different species of vultures of firstly classified into two groups, the old world vultures and the new world vultures. There are thought to be nearly 30 different species of vulture that are found worldwide.

The old world vultures are found in Asia, Europe and Africa with these species of vulture thought to be most closely related to eagles and hawks. The old world vulture is not thought to be closely related to the new world vulture and the old world vulture uses its spectacular sight alone in order to find food. The new world vultures are found in the Americas and although there are definitive similarities between the old world vulture and the new world vulture, they are believed to be connected through evolutionary status rather than DNA. The new world vultures tend to be slightly smaller than the old world vultures and use both sight and their excellent sense of smell in order to find their food. All species of vulture are similar in the sense that they scavenge for their food whenever possible rather than killing it themselves. Vultures feed on the remains of dead animals and are never too fussy about what is left. Vultures are known to strip meat, skin and even feathers, leaving only the skeleton of the animal remaining.

  

Although vultures are generally fairly solitary animals, groups of vultures are often seen circling prey from the sky above. This movement of the vultures is called a kettle and a group of vultures together is sometimes known as a venue. Vultures have keen eyesight. It is believed they are able to spot a three-foot carcass from four miles away on the open plains. In some species, when an individual sees a carcass it begins to circle above it. This draws the attention of other vultures that then join in. The feces of the turkey vulture contains strong acids that kill many of the bacteria commonly associated with bird feces. Because of their diet, these birds are able to kill harmful bacteria and viruses with their stomach acids, and halt the potential spread of disease from rotting carcasses.

Axolotl

Natural Wild Life | Axolotl | The axolotl is a medium-sized amphibian that is only found in one complex of lakes that are close to Mexico City. The axolotl, Ambystoma mexicanum, is a neotenic salamander, closely related to the Tiger Salamander. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. It is also called ajolote (which is also a common name for different types of salamander). The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate limbs.

The axolotl has a flat-shaped broad head that is much wider than the body of the axolotl. The axolotl also has feathery gills which protrude from either side of the head of the axolotl, allowing the axolotl to breath under water. As with newts and salamanders, axolotls are able to regenerate limbs that become damaged or detached meaning that axolotls have been extensively used in scientific experiments around the world. The axolotl is most commonly found in albino form as they spend a great deal of their lives hiding under rocks and in crevices on the bottom of the lake. Although axolotls are generally white or pink in colour, black, grey and brown coloured axolotls can also be found. The axolotl is a carnivorous animal meaning that the axolotl has a purely meat-based diet. The axolotl eats worms and insect larvae that develop under the surface of the water along with molluscs, crustaceans and some small species of fish. Due to the bottom-dwelling lifestyle of the axolotl, it has surprisingly few natural predators despite it's relatively small size. 

Birds and large fish are the most common predators of the axolotl along with humans who catch the axolotl to keep as pets in artificial environments. The axolotl can live for up to 25 years although the average axolotl rarely gets much older than the age of 15. Female axolotls can lay anywhere from 100 to 1,000 eggs which are coated with a sticky substance that helps them to stick to plants and rocks in the water to keep them safe. After about a month of development, tiny axolotl babies emerge into the open water. Today, the axolotl is considered to be a critically endangered species meaning that there are very few axolotl individuals left in the wild. Increasing levels of pollution is the most destructive factor in the survival to the axolotl with the ever-growing size of nearby Mexico City.
