Ok this is your guide on animals here you can learn and post about animals the posts must be atleast 1 paragraph here is the guide so far:
Written by Roadripper!!!- Eagles
Eagles are large birds of prey which are members of the bird order Falconiformes and belong to several thingd which are not necessarily closely related to each other genetically. Most of the more than 60 species occur in Eurasia and Africa. Outside this area, just two species (the Bald and Golden Eagles) can be found in the US and Canada, a few more in Central and South America, and three in Australia.
Eagles are differentiated from other birds of prey mainly by their larger size, more powerful build, and heavier head and bill. Even the smallest eagles, like the Booted Eagle (which is comparable in size to a Common Buzzard or Red-tailed Hawk), have relatively longer and more evenly broad wings, and more direct, faster flight. Most eagles are larger than any other raptors apart from the vultures.
Like all birds of prey, eagles have very large powerful hooked beaks for tearing flesh from their prey, strong legs, and powerful talons. They also have extremely keen eyesight to enable them to spot prey from a very long distance. This keen eyesight is primarily contributed by their extremely large pupils which cause minimal scattering of the incoming light.
Eagles build their nests in tall trees or on high cliffs. Many species lay two eggs, but the older, larger chick frequently kills its younger sibling once it has hatched. Eagles are sometimes used in falconry. They appear prominently in myth and literature. In the Old World, such references are commonly to the Golden Eagle.
Hope you enjoy!!

Green Sea Turtle
Feeding/Digestion: Juvenile Green Sea Turtles are carnivorous. When they are young they feed off jellyfish and other marine invertebrates. However, adult Green Sea Turtles are herbivorous, and live off marine plants such as algae. Their digestive system is actually similar to a cow�s. Food passes from the mouth, through the esophagus into the stomach, where the food begins to be digested by very specialized bacteria in their gut that help them to digest plant material. The food then passes through the small intestine where pancreatic enzymes and other digestive enzymes break the plant material down further. The food goes through the large intestine next, where electrolytes and water are removed from the food. The waste from a turtle�s meal is then passed through the anus.
Respiration: Though sea turtles live in the water, they breathe air with a pair of lungs. Sea turtles have been observed underwater, sleeping for up to six hours without having to resurface to breath. This extraordinary ability stems from the ability of their muscle tissue and blood to store oxygen for long periods of time. They also have the ability to take in oxygen through their cloaca in extreme conditions such as when they deep-sea dive or when they hibernation. Sea turtles are also able to retain a larger amount of carbon dioxide in their blood than other air-breathing animals. The lungs of a sea turtle are just like human lungs. Throughout the lungs, the tubes that lead into them (bronchii) split into smaller tube-like structures called bronchioles. The bronchioles lead to the alveoli, which are small sacs where the actual gas exchange takes place. The oxygen from the air diffuses into the blood and the carbon dioxide produced by the body diffuses into the air.
Internal Transport: Turtles have a closed double-loop circulatory. One of the two loops brings blood to and from the lungs, and the other loop brings blood to and from the rest of the body. Though some reptiles have four chambered hearts, sea turtles have only two atria on one ventricle that has a partial internal wall that helps keep oxygenated and deoxygenated blood separate during the pumping cycle. Blood is carried throughout the body by arteries, veins and capillaries, much like the circulatory system of a human.
Excretion: Much like other invertebrates, turtles eliminate liquid wastes in the form of urine, which is produced by the kidneys. Since sea turtles are water-dwelling reptiles, they don�t have to worry as much about water loss as terrestrial reptiles do. They excrete dilute ammonia. Sea turtles also have the ability to cry out salt. They have salt glands that empty into their eyes, and make them appear to be crying when they come ashore. This adaptation allows sea turtles to regulate the concentration of salt to water in their bodies and keep sand out of their eyes when they come on land to lay eggs.
Response: Turtles do not have visible ears, but have a single bone that serves as an eardrum covered by skin. This bone conducts vibrations to the inner ear. This enables turtles to hear best at low frequencies or respond to vibrations. They rely on their sense of smell more often, as it is excellent. Sea turtles have fairly good vision underwater, but on land they are nearsighted. Turtles have many nerves running through their flippers and shell, and have an especially good sense of touch on the soft part of their fins and top of their shell. The feeling of a tap on the top of their shell is almost proportionate to the feeling of a tap on a human cuticle. Sea turtles are not known to have many predators, apart from tiger sharks and sometimes killer whales. However, they are very well protected by their carapace (upper shell) and plastron (underside). The shell is a hard outer layer designed to protect the vulnerable organs within. The only parts of a sea turtle that is not protected by a shell are the head, fins and tail. However, sea turtles do not have the ability to retract their limbs into their shell as most terrestrial turtles do.
Movement: In water, sea turtles use their front fins to paddle and their back fins as rudders. They create a current in the water to propel themselves forward. On land, turtles are awkward and appear unaccustomed to movement on the beach. They use their fins to pull themselves up the beach to their nesting place.
How they fit In the World: Sea turtles are an important asset to their ecosystems. They are both predators and prey, and therefore provide food and a means to keep populations down in their ecosystems. However, the Green Sea Turtle has been marked endangered, as it is becoming more and more threatened by human developments on the beaches they lay their eggs on. People also eat turtles and their eggs as food. If they are to continue living in the wild, humans have to make an effort to save them by doing everything they can to save their ecosystems and the organisms themselves.
Written by Roadripper-Owls
Owls mostly hunt small mammals, insects, and other birds, though a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica, most of Greenland, and some remote islands. Though owls are typically solitary, the literary collective noun for a group of owls is a parliament. Owls have large forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers around each eye called a facial disc. Although owls have binocular vision, their large eyes are fixed in their sockets, as with other birds, and they must turn their entire head to change views. Most owls are nocturnal, actively hunting for prey only under the cover of darkness.
Written by Timegoesby- Brown Bears
Brown bears are great animals. They are usually dark brown, but can be light brown or black as well. Their life span is about 20-25 years. They are six to seven feet in length and three to three and half feet from shoulder to shoulder. They can weigh from 350-1500 pounds. They can reach a top speed of about 35 miles. The difference between brown bears and black bears is that grizzly bears have humps on their shoulders. In Canada it is called by its scientific name the brown bear, but in USA they are called grizzly bears because some times the tips of their hairs can be white giving them a grizzle look.
Brown bears are for the most part solitary animals. They only come in contact with other bears during breeding, places with a lot of food (like salmon rivers), and when the female is raising clubs. Hibernation is a huge part of a brown bears life style. They will sleep for about 5-8 months.
As an omnivore the brown bear almost anything. After hibernation they will spend a few months forging for fruit, berries, and insects. Next is the salmon season starts brown bears will go to the rivers to catch them. If a female bear has cubs with her though she will not stay very long, that is for the safety of the cubs. Which the other bears might kill. They will then go back to forging for food
Written by ManUtd4life096- Dinosaurs
Dinosaurs died out 65 Million years ago. But their fossils are still being found all over the world today. I'm here to tell you about these fascinating reptiles that once roamed our Earth a long, long time ago.
The Meat eaters were usually two legged dinosaurs. The smaller ones traveled in packs, and liked to take down larger dinosaurs, such as sauropods. Bigger ones however, like Tyrannosaurus Rex, hunted alone and usually sought out after 4 legged dinosaurs smaller than them. It is believed that T-Rex could run very fast, and charged at his victim with his huge mouth open.
The plant eaters, or Herbivores, were usually 4 legged animals. The most popular of their type were the Sauropods, who were long, 4 legged dinosaurs with long necks and tails. They traveled in herds, keeping the youngest or smallest in the center of the group. The largest dinosaur ever discovered was a sauropod as well. This was Seismosaurus, who, at 150 feet in length, shook the Earth when he walked.
Here are some fun facts:
Dumbest- Stegosaurus
Smartest- Troodon
Largest- Seismosaurus
Smallest- Compsognathus
Heaviest- Ultra Saurus
First- Iguanadon
Most Horned- Triceratops
Made by Roadripper- Penguins
Penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere. The number of penguin species is debated. The largest living species is the Emperor Penguin. Penguins seem to have no special fear of humans and have approached groups of explorers without hesitation. This is probably on account of there being no land predators in Antarctica or the nearby offshore islands that prey on or attack penguins. Penguins are superbly adapted to an aquatic life. Their wings have become flippers, useless for flight in the air. In the water, however, penguins are astonishingly agile. Within the smooth plumage a layer of air is preserved, ensuring buoyancy.
Written by Timegoesby- Polarbears
Polar bears live in the very northern part of the world. They do not hibernate and only about 400 are born a year. They are endangered animals.
There main source of food is seals. The polar bears haver great noses that allow them to smell though the ice into the seals dens, that could only be reached by underwater. The polar bear then breaks the ice to get at the seals. There color is transparent, but looks white due to the snow. Some scientist think that it should be considered a marian mammal due the it great swimming abilities.
After the seal season they must make a choice to follow the seals north, or go south. If they go south they enter grizzle country and have a hard time surviving because they do not know were to get food from. In resent years polar bears have ate from dumps to survive. When other bears go into hibernation the polar bears must wait until the ice freezes before they can head north. This can take some time.
Written by Roadripper- Monkeys
The many species of monkey have varied relationships with humans. Some are kept as pets, others used as model organisms in laboratories or in space missions. They may be killed in monkey drives when they threatened agriculture, or serve as service animals for the disabled.
In religion and culture, the monkey often represents quick-wittedness and mischief.A number of countries have used monkeys as part of their space exploration programmes, including the United States and France. The first monkey in space was Albert II who flew in the US-launched V2 rocket in June 14, 1949.Some characteristics are shared among the groups; most New World monkeys have prehensile tails while Old World monkeys have non-prehensile tails or no visible tail at all.

The elephant is a large land mammal. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 260 lb. An elephant may live as long as 70 years, sometimes longer. The tusks of an elephant are its second upper incisors. Tusks grow continuously; an adult male's tusks will grow about 7 in a year. Tusks are used to dig for water, salt, and roots; to debark trees, to eat the bark, and to move trees and branches when clearing a path. In addition, they are used for marking trees to establish territory and occasionally as weapons.
Written by Cool9654- Bald Eagle
The majestic Bald eagle is the national animal of the U.S.A. It can grow up to 96cm [3 feet] tall and its wing span up to 244cm [7 feet]. This large bird loves to soar peacefully in the sky above looking for its next meal which is usually fish. They make the biggest nest in the whole world and every year they add to it so it just get larger and larger. These outstanding birds were close to extinction because of DDT a type of pesticide that the bugs ate then the eagles ate them and their eggs shell would be very soft and break easy, but they have made a huge comeback and now they�re off of the endanger list thanks to the banning of DDT and protecting of there environment. So that is my paragraph about this beautiful, loving bird.
This is all for now hope you enjoyed this and learned more about animals!!!!
