  • The Sumatran rhinoceros is a small, hairy rhinoceros which survives in limited numbers in pockets of Indonesian and Malaysian rain forests. In the early 1900s it ranged over most of Southeast Asia from the Himalayas in Bhutan, eastern India through Malaysia, Sumatra and Borneo. Now they are only found in little forest pockets on the Indonesian island of Sumatra and the Malay peninsula.

  • The smallest living rhinoceros, the Sumatran rhinoceros has a gray-brown leathery hide. Its deep folds around the neck, behind the front legs, and before the hind legs give the rhinoceros an armor-plated appearance. It has a short, stocky body and stumpy legs which are covered with coarse reddish-brown hair. Its body length is from 8 to 8.5 feet and stands 4.5 feet at the shoulders. A mature rhino weighs from 2200 to 4400 pounds.
  • The Sumatran rhinoceros is the only Asian rhinoceros with two horns. Both sexes of rhinos have horns, the front horn being larger, averaging 15 to 20 inches. The male's horns are usually bigger than the female's, whose second, smaller horn is often absent. The upper lip curves down and can move around to grasp objects.

  • Information about the Sumatran rhino has been difficult to come by because it survives in small, scattered populations in the thick undergrowth of their rainforest habitat. It is known that the females have territories of about 1.2 to 2.2 miles in diameter that partially overlap with other females. The males seem to be nomadic. The estimated density per animal is approximately one animal per 15 sq. miles in high density areas, and one animal per 31 to 46 sq. miles in low density areas.
  • They live in a variety of habitats, but prefer higher elevations in the mountain moss forests and tropical rain forests with few human developments. The rhinos are most often found near water, and spend much of the day in mud wallows, which they dig out themselves and whose perimeters are kept clean. The wallows help the rhino avoid biting insects and protects them from the heat .
  • Sumatran rhinos are solitary animals who only come together to breed. Breeding of captive Sumatran rhinos has shown that the female will not come into estrus until she senses the nearness of a male. This reduces energy spent on cycling when the rhinos don't come into contact with each other on a regular basis. Gestation is 475 days with one calf per birth. The calf is covered with a dense coat of reddish hair. Calves are weaned at 18 month, but stay close to their mother for 2 to 3 years. Females reach sexual maturity at 4 years, and males take 7 years to reach sexual maturity. Birth intervals between calves is 3 to 4 years. The life span of captive rhinos is around 35 years.
  • Rhinos feed just before dawn and after dusk and move about during the night. The normal diet of the Sumatran rhino includes wild durian mangoes, figs, bamboo and plants species characteristic of disturbed forests. It will knock down saplings to get at the tender leaves. They are very fond of salt licks and each territory will include one.
  • The Sumatran rhinoceros is the smallest and rarest rhinoceros species. There are thought to be only 300 animals still in existence and the IUCN has put it on its critically endangered list in 1996. These survive in very small and scattered populations, their habitat fragmented into smaller and smaller pieces by encroaching human populations. The number of Sumatran rhinos has declined 50% due to poaching in the last 10 years. There are no signs that the situation is stabilizing. Efforts have been made by IUCN to set up a 3 year program for the protection to the Sumatran rhino in Indonesia and Malaysia in the wild. They are seeking to extend the program, whose funding ended in 1998. Captive breeding programs have also been set up, but have not been very successful. Since 1984 40 rhinos have been captured to participate in breeding programs, but 19 of these have died. Artificial insemination efforts have also not been very successful. These failures were the result of lack of knowledge of the diet and reproduction of the Sumatran rhinoceros. Experience so far has shown that the rhinos need larger enclosures with more natural conditions. Time is running out as efforts to save the Sumatran rhinoceros from extinction continue.
  • The Toco Toucan is the largest of the toucans. It can get to about twenty-four to twenty six inches in length. Its bill is brightly colored orange and black and can get to about eight inches in length. The Toco Toucan weighs about ten to seventeen ounces. The Toucan's massive bill is not as heavy as it looks; it has a hard outside and a hollow inside. A bright blue patch of blue skin surrounds the eye.

  • The rainforest is divided into five different layers, each with different plants and animals, adapted for life in the particular area. These are: the floor layer, the shrub layer, the undercanopy layer, the canopy layer and the emergent layer. Only the emergent layer is unique to tropical rainforests, while the others are also found in temperate rainforests.

  • The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level.[4] This makes it possible for people and other animals to walk through the forest. If the leaf canopy is destroyed or thinned for any reason, the ground beneath is soon colonized by a dense tangled growth of vines, shrubs and small trees called a jungle.[5]

  • An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest. Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.[14]

Rainforest Animals - 5 views

  • Scientists believe that there is such a great diversity of animals because rainforests are the oldest ecosystem on earth.
  • Many animals species have developed relationships with each other that benefit both species. Birds and mammal species love to eat the tasty fruits provided by trees. Even fish living in the Amazon River rely on fruits dropped from forest trees. In turn, the fruit trees depend upon these animals to eat their fruit, which helps them to spread their seeds to far-off parts of the forest.

  • DOZENS OF ANIMAL SPECIES A DAY BECOME EXTINCT IN TROPICAL RAINFORESTS
    • Thomas C
       
      WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  • When rainforests are destroyed, animals living outside the tropics suffer as well. Songbirds, hummingbirds, warblers and thousands of other North American birds spend their winters in rainforests, returning to the same location year after year. Less return north each spring, as few make it through the winter because their habitat has been destroyed. The cutting down of trees is not the only reason for species extinction. Thousands of monkeys and other primates are traded illegally on the international market each year, wanted for their fur, as pets, or for scientific research. Parrots and macaws have also become popular pets; buyers will pay up to $10,000 for one bird. Even the king of the jungle, the jaguar, is in danger of becoming extinct. Its fur is highly valued for use on coats and shoes.

  • Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests. One scientist found 50 different species of ants on a single tree in Peru! You would probably only need a few hours of poking around in a rainforest to find an insect unknown to science.
  • In some cases both species are so dependent upon each other that if one becomes extinct, the other will as well. This nearly happened with trees that relied on the now-extinct dodo birds. They once roamed Mauritius, a tropical island located in the Indian Ocean. They became extinct during the late 19th century when humans overhunted them. The calvaria tree stopped sprouting seeds soon after. Scientists finally concluded that, for the seeds of the calvaria tree to sprout, they needed to first be digested by the dodo bird. By force-feeding the seeds to a domestic turkey, who digested the seeds the same way as the dodo birds, the trees were saved. Unfortunately humans will not be able to save each species in this same way.

  • The constant search for food, water, sunlight and space is a 24-hour pushing and shoving match. With this fierce competition, you may be amazed that so many different species of animals can all live together. But this is actually the cause of the huge number of different species.The main secret lies in the ability of many animals to adapt to eating a specific plant or animal, which few other species are able to eat. Have you ever wondered, for instance, why toucans and parrots have such big beaks? These beaks give them a great advantage over other birds with smaller beaks. The fruits and nuts from many trees have evolved with a tough shell to protect them from predators. In turn toucans and parrots developed large strong beaks, which serves as a nutcracker and provides them with many tasty meals.
    • Gurupranav G
       
      This peice of information will be useful if you are looking at the adaptations of different animals in the rainforest. This is useful for me.
  • Each species has evolved with its own set of unique adaptations, ways of helping them to survive. Every animal has the ability to protect itself from being someone's next meal. The following are just a few of these unique and often bizarre adaptations. CAMOUFLAGE The coloring of some animals acts as protection from their predators. Insects play some of the best hide-and-go-seek in the forest. The "walking stick" is one such insect; it blends in so well with the palm tree it calls its home that no one would notice it unless it moved. Some butterflies, when they close their wings, look exactly like leaves. Camouflage also works in reverse, helping predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. SLOW AS A SNAIL The three-toed sloth is born with brown fur, but you would never know this by looking at it. The green algae that makes its home in the sloth's fur helps it to blend in with the tops of the trees, the canopy, where it makes its home. But green algae isn't the only thing living in a sloth's fur; it is literally "bugged" with a variety of insects. 978 beetles were once found living on one sloth! The sloth has other clever adaptations. Famous for its snail-like pace; it is one of the slowest-moving animals on earth. (It can even take up to a month to digest its food!) Although its tasty meat would make a good meal for jaguars and other predators, most do not notice the sloth as it hangs quietly in the trees, high up in the canopy. DEADLY CREATURES Other animals want to announce their presence to the whole forest. Armed with dangerous poisons used in life-threatening situations, their bright colors warn predators to stay away. The coral snake of the Amazon, with its brilliant red, yellow, and black coloring, is recognized as one of the most beautiful snakes in the world, But don't admire its beauty too long; its deadly poison can kill within seconds The poison arrow frog also stands out with its brightly colored skin. Its skin produces some of the strongest natural poison in the world, which Indigenous people often use for hunting purposes. Another animal with no friends is the hoatzin. Often called the stinkbird, it produces a horrible smell to scare

      Most of these species, we haven't discovered their uses yet. We don't care that we don't even know what they are and never will
  • Rivers have become both overfished and polluted. Gillnets now allow fishermen to kill huge amounts of fish at a time. They often use only the larger and more profitable fish, dumping the dead smaller fish and other animals such as dolphins back into the rivers.
    • Chloe W
       
      This is terrible. We are losing our air supply, and now our water supply is getting polluted. I hope we can stop it.
  • Tropical rainforests are home to many of the strangest-looking and most beautiful, largest and smallest, most dangerous and least frightening, loudest and quietest animals on earth. You've probably heard of some of them; jaguars, toucans, parrots, gorillas, and tarantulas all make their homes in tropical rainforests. But have you ever heard of the aye-aye? Or the okapi? There are so many fascinating animals in tropical rainforests that millions haven't been named or even identified yet. In fact, about half of all the world's species live in tropical rainforests.

      How can we save the animals
  • During the Ice Ages, the last of which occurred about 10,000 years ago, the frozen areas of the North and South Poles spread over much of the earth, causing huge numbers of extinctions. But the giant freeze did not reach many tropical rainforests. Therefore, these plants and animals could continue to evolve, developing into the most diverse and complex ecosystems on earth. The nearly perfect conditions for life also help contribute to the great number of species. With temperatures constant at 75 -80 degrees F. the whole year, animals don't have to worry about freezing during cold winters or finding shade in the hot summers. They rarely have to search for water, as rain falls almost every day in tropical rainforests. Some rainforest species have populations that number in the millions. Other species consist of only a few dozen individuals. Living in limited areas, most of these species are endemic, or found nowhere else on earth. The maues marmoset, a species of monkey, wasn't discovered until recently. Its entire tiny population lives within a few square miles in the Amazon rainforest. It is so small, it could sit in a person's hand!

  • Leaf-cutter, or parasol ants, can rightfully be called the world's first farmers. They climb trees up to 100-feet tall and cut out small pieces of leaves. They then carry these fragments, weighing as much as 50 times their body weight, back to their homes. Sometimes they must travel 200 feet, equal to an average human walking about 6 miles with 5,000 lbs. on his/her back! The forest floor is converted to a maze of busy highways full of these moving leaf fragments. These ants don't eat the leaves they have collected, but instead bury them underground. The combination of leaves and substances that the ants produce such as saliva allows a type of fungus to grow. This fungus is the only food that the ants need to eat. Azteca ants live on the swollen thorn acacia tree, which offers the ants everything needed for survival - lodging, water, and food for themselves and their young. In return, the ants protect the trees from predators. Whenever the ants feel something brush against the tree, they rush to fiercely fight the intruder. They also protect it from vines and other competing plants that would otherwise strangle it. As a result, nothing can grow near these trees. They are the only trees with a built-in alarm system!

Tropical Rainforests - 0 views

  • Because there are so many creatures living in the rainforest, there is a great deal of competition for food, sunlight and space. Some animals became very specialised. This means that they adapted to eating a specific plant or animal that few others eat. For example, parrots and toucans eat nuts, and developed big strong beaks to crack open the tough shells. Leafcutter ants climb tall trees and cut small pieces of leaves which they carry back to their nest.The leaf pieces are about 50 times their weight.The ants bury the leaf pieces, and the combination of the leaves and the ants' saliva encourages the growth of a fungus, which is the only food these ants eat. Sometimes there are relationships between animals and plants that benefit both. Some trees depend on animals to spread the seeds of their fruit to distant parts of the forest. Birds and mammals eat the fruits, and travel some distance before the seeds pass through their digestive systems in another part of the forest. One problem with specialisation is that if one species becomes extinct, the other is in danger too unless it can adapt in time. The dodo, a flightless bird of Mauritius, became extinct in 1681. Today there are just 13 calvaria trees left on the island, each over 300 years old, and nearly at the end of their life. Scientists realised that the seeds had to pass through a dodo's digestive system before they could germinate. It seemed that the tree species would also become extinct, but scientists tried domestic turkeys and have successfully managed to germinate some seeds.Many rainforest animals use camouflage to 'disappear' in the rainforest. Stick insects are perfect examples of this. There are some butterflies whose wings look like leaves. Camouflage is of course useful for predators too, so that they can catch prey that hasn't seen them. The Boa Constrictor is an example of a camouflaged predator. The South American three-toed sloth uses camouflage and amazing slowness to escape predators. Green algae grows in the sloth's fur, which helps camouflage it in the forest canopy. Sloths are among the slowest moving animals of all (inside too, as it takes about a month to digest food). They hang from branches in the canopy, and are so still that predators such as jaguars don't see them. Some animals are poisonous, and use bright colors to warn predators to leave them alone. There are several species of brightly colored poison arrow frogs. Native Central and South American tribes used to wipe the ends of their arrows onto the frog's skin to make their arrows deadly
