Some lemurs such has the ring tail lemur has shown behavioral change to the changing environment by doing such things as using people's crops as a food source. The lemur is evolving, some researchers speculate that there may be as many as 20 new species of lemurs by the next generation.…
They sometimes attack animals from farmhouses, but more often they simply scavenge for food instead. They eat carrion and roadkill whenever they find it and sometimes eat fruits and plants. They also eat injured and sick animals. When they are not scavenging for food that is already dead, they hunt smaller prey like possums, rabbits, and birds. In rare events, large Dingo groups have been known to attack a human, but Dingoes normally give humans their space.…
They usually compete with several different birds, including the Great Horned Owl for nesting sites. They are carnivorous. Diet is composed of small mammals such as rabbits and rodents. It will also prey on snakes, lizards, birds, and fish. It is an opportunistic feeder and feed on whatever is available. It usually hunts from an elevated perch.…
The capybara is the largest rodent in the world. The capybara's name comes from the native people of South America. It means "master of the grass." The scientific name of the capybara is hydrochoerus hydrochaeris, which means "water pig" in Greek. Capybaras have been in existence since the Pleistocene epoch. Their ancient ancestors were rodents that lived about sixty million years ago. The average size of a capybara is four feet in length and two feet in height. This is about the size of a sheep. Capybaras usually weigh between sixty and one hundred and forty pounds. Many people think the capybara looks like a larger version of a guinea pig. All capybaras have large flat noses, webbed feet, short legs, and no tail. Their fur is very coarse and it is usually a reddish-brown color. Capybaras also have large incisor teeth that continuously grow. Capybaras must constantly gnaw and chew on wood and nuts to wear their teeth down. To protect themselves from the hot sun, capybaras will often rest in nearby pools of water. They will also be found lying mud or in the shade.…
Primary consumer Omnivore. The cane toad is at the least concern of environmentalist because its numbers are huge and it is thriving. The cane toad eats small rodents, reptiles, other amphibians, birds and invertebrates they also eat plants, dog food and household trash. What eats it snakes, catfish, and eels. When the cane toad feels like it is in danger it can release a deadly toxin called bufotenin and if the toxin enters the blood stream it may cause death in the predator.…

A snowy owl feeds on small mammals, such as, rabbits, squirrels and lemmings; however, they will eat seabirds and fish when the opportunity presents itself. The snowy owl will perch itself up on a fence post, building, telephone poll and patiently wait for prey (National Georaphic). Snowy owls spend a large amount of time sitting and waiting, often sitting right on the ground. The snowy owl has superior eyesight and hearing, allowing it to find prey hidden in brush or snow (National Georaphic). The snowy owl can turn their head two hundred and seventy degrees around, which aids them and finding a small animal on the ground to devour. The snowy owl has many hunting techniques; they swoop down, hover, jump, and even run after their prey. The snowy owl will swoop down on their prey and snatch them up with their sharp talons while hovering in the air. They will catch and pull a fish or duck right out of the water (Miller, 1999). The snow owl will also use an aerial dive while attacking prey. Once the snowy owl spots their prey they will run after it and pounce upon its prey, swallowing the whole critter down in one swallow, head first. The snowy owl will then regurgitate a pellet. These pellets consist of the parts of the food source that cannot be digested, such as the animal’s bones and hair (The Alaska Zoo). Feeding primarily on lemmings, the snowy owl will eat three to five lemmings a day. With the average weight of a lemming being four pounds, the snowy owl will feed on up to sixteen pounds of lemmings a day. Meaning the snowy owl eats up to two and a half times its body weight in an average…
People moving into their areas and cutting down trees is making it challenging for lemurs to survive. Bamboo is becoming rare and that is a source of survival for lemurs.…
No matter what they plan to make their next meal, monkeys have developed adaptations that help them hunt their food. Prehensile tails, large family groups and the use of tools all make sure monkeys have a full belly. Prehensile means they are able to use their tail almost like a third hand, using it to help them hang or climb from branches. The head and body of adult howler monkeys range from twenty-two to thirty-six inches long and their tail adds twenty-three to thirty-six inches. Other monkeys such as capuchins and howler monkeys use their tails to get around in their homes, which is trees. Since most of their diet contains leaves, having a prehensile tail makes reaching almost all parts of the tree for a meal a breeze. They also use their tails to hang from branches while…
Predators: There are few predators of the moose but a pack of wolves, brown bears, cougars, and killer whales (when the moose are swimming) are known to be predators of the moose. Humans are also a threat to moose, as we hunt them for their meat and fur and kill them while driving along highways.…

Giraffes are the tallest land mammal on earth. A giraffe’s leg alone is at least 6ft tall. That is as tall as a person! A giraffe’s neck is also 6ft long and weighs at least 600 pounds. The average male giraffe weighs around 2,600 pounds and is 16ft to 20 ft tall. The average female giraffe ,however, is smaller than the the male giraffe(also known as a Bull) by 800 pounds! a female giraffe…

A group of scientists lead by Biren Patel have recently found a partial mandible of an ancient primate related to lemurs. Scientists have named the new species Ramadapis sahnii and claim that it existed 11 to 14 million years ago, and is a member of the early primate family Sivaladapidae. Analysis of the jawbone shows that the species consumed leaves and was approximately the same size as a house cat, or to a modern day lemur. This discovery is important to the scientific community as with this discovery more information surrounding the evolutionary history of primates can be gathered and analysed. This new species will also help expand the phylogenetic tree for primates, making it significant to any scientist researching primate evolution.…
