         <description><![CDATA[<div>Black rhinoceroses have a sort of attack-first-and-ask-questions-later attitude. When a rhino catches the scent of a human or anything else unfamiliar, it is likely to charge. Rhinos can't see well, so they sometimes charge objects like trees and rocks, mistaking them as threats. But rhinos have keen senses of smell and hearing.<br><br>Rhinos sometimes fight with each other. Black rhinos use the bigger of the two horns on their noses as weapons in a fight.<br><br>Their horns, made of a substance similar to that of human fingernails, sometimes break off, but they regenerate, or grow back. Female rhinos also use their horns to protect their babies from predators such as lions, crocodiles, and hyenas.<br><br>In spite of their fierce reputation, black rhinos do have a softer side. The females are very attentive mothers. They look after their young for years, protecting them from enemies and teaching them how to survive independently. Young rhinos usually stay with their mothers until a sibling is born. By then they're generally over two years old, almost adult size, and ready to live on their own.<br><br>Humans are the only real threat to adult black rhinos. In several Asian cultures, people believe that a rhino horn provides powerful medicine for a variety of ailments. Other people, who live mainly in northern Africa, use rhino horns to make the handles for special daggers. Since rhino horns fetch high prices, many poachers are willing to break the law and kill these endangered animals.<br><br>There are five different species of rhinoceros: black, white, Javan, great Indian, and Sumatran.</div><div><br></div>]]></description>

         <description><![CDATA[<div>For all of their roaring, growling, and ferociousness, lions are family animals and truly social in their own communities. They usually live in groups of 15 or more animals called prides. Prides can be as small as 3 or as big as 40 animals. In a pride, lions hunt prey, raise cubs, and defend their territory together. In prides the females do most of the hunting and cub rearing. Usually all the lionesses in the pride are related—mothers, daughters, grandmothers, and sisters. Many of the females in the pride give birth at about the same time. A cub may nurse from other females as well as its mother. Each pride generally will have no more than two adult males.&nbsp;<br><br>While the females usually live with the pride for life, the males often stay for only two to four years. After that they go off on their own or are evicted by other males who take over the pride. When a new male becomes part of the pride it is not unusual for him to kill all the cubs, ensuring that all future cubs will have his genes. The main job of males in the pride is defending the pride's territory. A male's loud roar, usually heard after sunset, can carry for as far as five miles (eight kilometers). The roar warns off intruders and helps round up stray members of the pride.<br><br>Hunting generally is done in the dark by the lionesses. They often hunt in groups of two or three, using teamwork to stalk, surround, and kill their prey. Lionesses aren't the most successful of hunters, because they usually score only one kill out of several tries. After the kill the males usually eat first, lionesses next—and the cubs get what's left. Males and females fiercely defend against any outside lions that attempt to join their pride.&nbsp;<br><br></div>]]></description>

         <description><![CDATA[<div><strong>1) </strong>Our planet is home to three different species of zebra, the <strong>plains zebra</strong>, <strong>Grevy’s zebra</strong> and <strong>mountain zebra</strong>, all three species are native to Africa.<br><br></div><div><strong>2)</strong> The most common species is the plains zebra, which roams grasslands and woodland of eastern and southern Africa. The Grevy’s zebra can be found in dry, semi-desert areas of Kenya and Ethiopia, and the mountain zebra lives in mountainous and hilly habitats in Namibia, Angola and South Africa.<br><br></div><div><strong>3)</strong> Closely related to horses, zebras have thick bodies, thin legs, a tufted tail, and a long head and neck sporting a short mane. And their most famous feature? Their <strong>brilliant black-and-white striped coat</strong>, of course!<br><br></div><div><strong>4)</strong> So why do zebras have stripes? Well, scientists aren’t entirely sure. Their stripes perhaps serve to dazzle and confuse predators and biting insects, or to control the animal’s body heat. Because <strong>each individual’s stripes are unique</strong>, their stripes may also have a social purpose, helping zebras to recognise one other.<br><br></div><div><strong>5)</strong> These cool creatures are herbivores and spend most of their day eating grass, and sometimes leaves, shrubs twigs and bark, too. Their teeth are well adapted for grazing, with sharp incisors at the front of their mouth to bite the grass, and large molars at the back for crushing and grinding.<br><br></div><div><strong>6)</strong> Zebras are constantly on the move for fresh grass to eat and water to drink. Super stealthy creatures, they’ll travel thousands of kilometres in search of green pastures where they can fill their bellies and quench their thirst!<br><br></div><div><strong>7)</strong> Zebras are social animals and live together in large groups, called herds. As they migrate to new feeding grounds, ‘super herds’ may form consisting of thousands of individuals. They may team up with other grazers on their travels, too, such as antelope and wildebeest.<br><br></div><div><strong>8)</strong> Within a herd, zebras tend to <strong>stay together in smaller family groups</strong>, made up of a dominant male, several females (called ‘mares’) and their young (called ‘foals’). When they are between one and three years old, males (or ‘stallions’) leave to join ‘bachelor herds’ (all-male groups), where they stay until they’re old enough and strong enough to compete for females.<br><br></div><div><strong>9)</strong> As elegant and peaceful as they are, don’t be fooled – zebras can be aggressive animals, too! Stallions fight for females with piercing bites and powerful kicks that are strong enough to cause serious damage – and sometimes even kill!<br><br></div><div><strong>10)</strong> Their <strong>fierce fighting skills</strong> and strong social bonds help to protect zebras from predators, which include lions, leopards, hyenas and chetahs. When under threat, these awesome animals form a semi-circle facing the attacker, and prepare to strike if need be. And if one of the group is wounded or injured, other zebras will circle around and attempt to drive off the hungry attacker. All for one and one for all!<br><br></div>]]></description>

         <description><![CDATA[<div>The largest living land animal, the African elephant lives both on the grasslands (savannahs) and in the forests. African elephants in grasslands regions tend to live in larger groups than those who live in the forests. In fact, savannah elephants may join together in loosely knit clans of up to 70 members! But most often they can be found roaming about in a basic family unit of about 10 elephants. According to the WWF, important populations of African elephants occur in Tanzania, Botswana, and Zimbabwe, and probably in Congo, Gabon, and the Democratic Republic of Congo.<br><br>- Elephants live approximately 70+ years.</div><div>- Although massive, they can run at speeds of up to 25 miles per hour and trample almost anything in their way.</div><div>- An elephant will lose and regrow its teeth six times during its lifetime.</div><div>- A healthy adult elephant has little to fear from predators, except human beings.&nbsp; It's greatest threats come from poachers and habitat loss.</div><div>- Elephants can communicate with each other over great distances using infrasound, vocalizations that are at such low frequency they cannot be heard by the human ear.</div><div>&nbsp;- Elephants are highly intelligent creatures with very large and complexly organized brains.&nbsp; Not only do they have the largest brain of any land animal, but the structure and complexity of their brains is similar to that of a human.</div><div>- Unlike your dog or cat an elephant can actually reconize itself in a mirror.&nbsp; Other animals that share this trait include dolphins, apes, magpies, and of course humans.</div><div>&nbsp;- Contrary to a popular old myth elephants are NOT afraid of mice, but they do try to avoid bees and ants.&nbsp;</div><div>- The skin of an elephant is about one inch thick yet so sensitive that it can feel a fly land.</div><div>&nbsp;</div><div><br><br></div>]]></description>

         <description><![CDATA[<div>Giraffes grow about 4 feet (1.2 meters) in their first year of life. A newborn giraffe is about 6 feet (1.9 meters) tall at birth and weighs about 150 pounds (68 kilograms). ​<br><br>​ Many young giraffes, called calves, die from lion attacks during their first year of life. Once a giraffe reaches adulthood its height is often enough to protect it from lions. Adult giraffes, however, must still be careful of lions when they are bending down to drink water or rest. Usually giraffes will drink or rest in shifts so that at least one giraffe is always on the lookout for approaching predators.​<br><br>​The giraffes' height and excellent vision give them a wide view of the grasslands where they live, making it easy to spot predators from a distance. Some scientists believe that other animals—such as zebras, antelope, and wildebeests—often congregate near giraffes to take advantage of their ability to see danger from a distance. The giraffe could be considered the early warning system of the African grasslands.</div>]]></description>

         <description><![CDATA[<div>&nbsp;Rattlesnakes live in many places and habitats in the Western Hemisphere, from mountains to deserts and plains.&nbsp;<br><br>There are more than 24 rattlesnake species and all of them have that most-famous feature: the rattle! The rattle is found at the tip of the rattlesnake’s tail. The snake uses the rattle to warn potential aggressors to back off or to distract prey. The famous rattle noise comes from the sound created when hollow and bony doughnutlike segments in the rattle bang together.&nbsp;<br><br>As rattlesnakes age, segments on the end of the rattle wear out and break off. New segments grow when the rattlesnake sheds its skin, or molts. Like other snakes, rattlesnakes don’t have ears and can’t hear most sounds. They detect movement by sensing vibrations in the ground. Their eyes see well even in low light.&nbsp;<br><br>The rattlesnake’s triangular head contains a hollow spot between the eyes and nostrils called a pit. This pit is actually a sensory organ that helps the rattlesnake hunt in darkness by detecting body heat.&nbsp;</div>]]></description>

         <description><![CDATA[<div><br></div><div><strong>1. </strong>Turtles belong to one of the oldest reptile groups in the world – beating snakes, crocodiles and alligators!<br><br></div><div><strong>2. </strong>These creatures date back to the time of the dinosaurs, over 200 million years ago – woah!<br><br></div><div><strong>3. </strong>Turtles are easily recognised by their bony, cartilaginous <strong>shell</strong>. This super-tough casing acts like a shield to protect them from predators – some turtles can even tuck their head up inside their shell for extra protection!<br><br></div><div><strong>4. </strong>Just like your bones, a turtle’s shell is actually part of its skeleton. It’s made up of over <strong>50</strong> <strong>bones</strong> which include the turtle’s <strong>rib cage</strong> and <strong>spine</strong>.<br><br></div><div><strong>5. </strong>Contrary to popular belief, a turtle cannot come out of its shell. The turtle’s shell grows with them, so it’s impossible for them to grow too big for it!<br><br></div><div><strong>6. </strong>What a turtle eats depends on the environment it lives in. Land-dwelling turtles will munch on <strong>beetles</strong>, <strong>fruit</strong> and <strong>grass</strong>, whereas sea dwellers will gobble everything from <strong>algae </strong>to <strong>squid</strong> and <strong>jellyfish</strong>.<br><br></div><div><strong>7. </strong>Some turtles are <strong>carnivores</strong> (meat eaters), others are <strong>herbivores</strong>(plant eaters) and some are <strong>omnivores</strong> (a mixture of the two!). Many baby turtles start life as carnivores but grow to eat more plants as they mature.<br><br></div><div><strong>8.</strong> Turtles are ‘<strong>amniotes</strong>’ – they breathe air and lay their eggs on land, although many species live in or around water.<br><br></div><div><strong>9. </strong>These cold-blooded creatures have an incredibly long life span. The oldest ever recorded, named <strong>Tu”i Malila</strong>, of Tonga Island, passed away at the grand old age of <strong>188</strong>!<br><br></div><div><br></div><div><strong>10. </strong>Sadly, many species of turtle are endangered! <strong>129</strong> of approximately 300 species of turtle and tortoise on Earth today are either vulnerable, endangered, or critically endangered, according to the <strong>IUCN</strong>.

         <description><![CDATA[<div> Parrot is a type of colorful bird. There are 372 species of parrots that mostly inhabit tropical and subtropical areas of South and Central America, Asia, Africa, Australia and New Zealand. Few species of parrots prefer life in colder climate. Macaws, Amazons, kea, kaka, lorikeets, parakeets, lovebirds and cockatoos are well known species of parrots. Because of their beauty and intelligence, parrots are one of the most popular pets in the world. Unfortunately, due to illegal pet trade, nearly 100 species of parrots are critically endangered in the wild. Besides illegal pet trade, certain species of parrots are endangered due to habitat loss.<br><br><strong>Interesting Parrot Facts:</strong><br>- Parrots can reach 4 to 40 inches in length, depending on the species. Smallest species of parrot, buff-faced pygmy parrot, is only 3 inches long and weighs 0.4 ounces. Kakapo is the largest parrot. It can reach 9 pounds of weight.</div><ul><li> All parrots are brightly colored.</li><li> All parrots have curved beaks and strong legs that end with four toes. - Two toes are positioned forward and two backward.<br>- </li><li>Arrangement of toes and sharp claws facilitate life on the trees and ensure firm grip when parrots rest on the branches.<br>- </li><li>Parrots are the only birds that are able to pick food with their feet and bring it to the mouth.<br><br></li><li>Parrots are able to imitate human voice. Only domesticated parrots have this unusual habit.<br><br></li><li>Parrots are extremely intelligent animals. African grey parrot, named Alex, managed to learn to count to 6, answer the questions, recognize 7 colors and identify 35 different objects.<br><br></li><li>Parrots can be active during the day (diurnal animals) or night (nocturnal animals), depending on the species.<br>Parrots are omnivores (they eat other animals and plants). Their diet consists of seed, nuts, fruit, flowers and insects.<br><br></li><li>Parrots live in large groups called flocks that usually consist of 20 to 30 animals.<br><br></li></ul>]]></description>

         <description><![CDATA[<div>&nbsp;</div><div>Measuring 63.5 cm (25 in.) in length, the toco toucan is the largest of all toucans. Its black body and white throat are overshadowed by its most recognizable trait: a large colorful beak.<br><br></div><div>The bright orange beak is about 19 cm (8 in.) long – one third of the bird’s total length. But despite its substantial size, the beak weighs less than you may think. Composed of the protein keratin, the structure of beak incorporates many air pockets allowing for a very low mass.&nbsp;<br><br>&nbsp;</div><div>Toco toucans also use their beaks to pluck and peel fruit, their main source of food. In addition, the beak houses a flat tongue of the same length, which helps the toucan catch insects, frogs, and reptiles. Toco toucans also occasionally eat the eggs of other birds.<br><br></div><div>Although they spend a lot of time in trees, they are not very good at flying. Toucans mainly travel among trees by hopping. When they do take flight, they flap their wings vigorously and glide, traveling only short distances.<br><br></div><div>Toucans nest in the hollows of trees. They often move into cavities created and abandoned by woodpeckers.<br><br></div><div>Several toucans live together in a single hollow. It is in these hollows that they lay their eggs, generally two to four a year. Both parents incubate the eggs for 16-20 days. Once the chicks hatch, both parents continue to care for the young. Baby toucans are not born with an excessively large beak; the beak grows as the birds develop.<br><br></div><div>Native to South America, toco toucans inhabit a range of habitats including tropical forests, savannas, and shrubland.&nbsp;<br><br></div>]]></description>
