...The Italian attack on the British forces in Egypt was first to agree with Operation Sea lion. the planned but never happened German sea invasion of Britain in 1940. When it had become possible to Mussolini that Sea lion was put on hold forever, he ordered Marshal Rodolfo to launch his 10th army, consisted of seven divisions, into combat across the Egyptian border from Libya. Field Marshal Graziani led his large number of major Italian forces across the Libyan-Egyptian border in September 1940 against a smaller but powerful mobile British enemy. The campaign was a disaster, and by December of that year, the Italian forces in Northern Africa were on the verge of a certain collapse. Although German Field Marshal Rommel’s leadership skill and...

...killing many sea lions along the Pacific Coast. The toxin is called domoic acid, and it kills the sea lion’s brain cells. In sea lions, the decrease of brain cells from the domoic acid is causing memory loss, and worsening navigational skills. This makes it very hard for the sea lions to survive, because they need their navigational skills to hunt for food. The toxic algae causing this problem mostly blooms in the Spring, and then last a few weeks. But, this year’s bloom from the Spring, all the way to the Summer. Also, instead of only finding sick sea lions in California, people have found them all the way up in Washington and Oregon. Scientist Peter Cook picked up 30 sea lions, and put...

...Galapagos Sea Lion The Galapagos sea lion is found on islands in the Galapagos Archipelago and off the coast of Ecuador where a population has been introduced, they have also been found in Costa Rica. The Galapagos sea lion, Zalophus wollebaeki is the scientific name, is fundamentally a coastal animal and is rarely found more than 16 kilometers out in sea. And these sea lions are now on the endangered species list (proquest.com). I think people should be held accountable for hunting and killing an endangered species and we should use any resource possible to save the Galapagos sea lion. The population fluctuates between 20,000 and 40,000 animals. A census in 1978 submitted a population size of about 40,000, but a recent survey in 2001 found a 50% decline from this earlier estimate (Alava and Salazar 2006). The running differences might exist between counts over this period, but this decline suggested is cause for serious concern (proquest.com). The Galapagos sea lion are active during the day and hunt in mostly shallow water, where they feed on fish, octopus, and crustaceans. Sea lions are also capable of making extremely deep dives of up to 200 meters and for 20 minutes or longer, then rapidly surfacing with no ill health effects. When the animals are on shore, the Galapagos sea lions rest on the sands of the beaches and rocky areas in colonies of usually groups of thirty or more (life-sea.blogspot.com). They are extremely social animals and pack together on the shore...

...Panthera is a genus of large, wild cats in the mammalian family, Felidae, and includes the four, well-known living species of the lion (Panthera leo), the tiger (Panthera tigris), the jaguar (Panthera onca), and the leopard (Panthera pardus). These four extant cat species are considered unique in having the anatomical changes enabling them to roar. (New World Encyclopedia) The Panthera genus comprises about half of the seven extant species in the Pantherinae subfamily also known as the "big cats" family, the other species typically belonging to the genera Neofelis and Uncia, although taxonomy has been continually in flux. The name panther sometimes is used to designate collectively cats in this subfamily. (New World Encyclopedia) The tiger (Panthera tigris) is the largest felid species and a widely recognized symbol of wildlife conservation.

...Sharks are afraid of us, they can sent our energy as soon as we are in the water. Two third of earth is under water and over 80% of life on earth is in the oceans. Life on earth evolves from the sea, and the animals who evolves and stayed for over four hundreds years are the sharks. They manages to survive, they are architect of our world. They are the lions and tigers of the sea. Sharks are in danger. They are hunted by humans for their fins with lines. The population does not realize the massacre that sharks are victims of. Predators are controlling the ecosystems.The oceans are the life support system of the planet, change this life support would be a real threat. The world is afraid of sharks and do not see the importance to help sharks or to save them. The first help requires by sharks conservators are to consider sharks as a real animal and stop thinking that sharks are a threat. The population does not realize the facts. Sharks kill five people each year, elephants and tigers over one hundred per year. The first solution to the sharks conservation problem would be to change the mentality of the population. There is a mythology around sharks creating fear, but there is the same problem for wales with the legend of Mobidick. It is portrait as a monster of the seas. Asia population eat sharks because they think that sharks have powers to make them stronger because sharks do not often get sick. But there is Sand 1 no scientific fact to prove it and it's...

...A lynx is any of the four species within the Lynx genus of medium-sized wild cats. The name "lynx" originated in Middle English via Latin from the Greek word λύγξ, derived from the Indo-European root leuk- ("light, brightness") in reference to the luminescence of its reflective eyes. A lynx’s keen vision earns this cat legendary status in the myths of many cultures. In Greek, Norse, and North American myths, the lynx sees what others can’t, and its role is revealing hidden truths. The lynx is known by the tuft of black hair on the tips of its ears and its short or bobbed tail.In fact, one species of lynx is called a bobcat! 2 The four species of lynx are: Canadian, Eurasian, Spanish lynx and the bobcat. The Canadian lynx live in Canada and also in the northern US, including Alaska, this cat is also known as the North American lynx.It has extremely thick, light brown or gray fur with light black spots.Features unique to the Canadian lynx include a black tail tip and huge paws with long, thick fur to keep the cat’s toes warm in the winter. It can spread its toes out wide like snowshoes for walking in soft snow. 2 The Eurasian lynx is the most numerous of the lynx species and the most widespread, currently found in 46 countries in Europe, northern Asia, and the Middle East!It has long, thick, light-colored fur that is silky in the winter and shorter, thinner, and darker-colored in the summer.

...Appearance The bald eagle, or Haliaeetus leucocephalus, is a type of bird. Adult bald eagles are distinguishable due to their white head and tails, a contrast to their brown body. Young bald eagles have splotches of white, located on their tails and undersides. They also have a curved, pointed yellow beak. Bald eagles typically reach around one meter (three feet) in height, with a seven foot wingspan. Males weigh between eight and nine pounds, while females weigh ten to fourteen pounds. Location Bald eagles are found throughout North America. Although they live on most of the continent, bald eagles can mainly be found near sources of water such as ponds, lakes, rivers, and streams. It is not uncommon, however, for bald eagles to make their nest in pine forests near the coastline. Diet Bald eagles will eat a variety of foods, including small animals, waterfowl, wading birds, dead animals (also known as ‘carrion’), rodents, and smaller birds. They obtain this food by finding already dead animals, stealing it from other birds, or, of course, gathering the food on their own. Bald eagles typically consume between ½ - 1 pound of food per day. Though adult bald eagles have few natural predators, young bald eagles can be eaten by gulls, crows, hawks, bobcats, black bears and raccoons. Reproduction Bald eagles reproduce sexually. The mating season is any time between late September and early April. Bald eagles lay eggs five to ten days after mating, and the eggs are incubated for...

...We Can Learn a lot from Nature's own Organization: A Look into the African Lion's Social Grouping Forget single sex classrooms; in order for education to be most beneficial, classrooms should be modeled after a lion's pride. The understood order of the classroom activities and daily progress would allow a much more adequate environment for both student and teacher. A hierarchy should be established early in a classroom with a high female to male ratio. Research shows that females perform much better from an academic standpoint in a environment were they are able to socialize. "Girls helped one another to understand and complete the in-class group work. The were able to accomplish problem solving, decision making, and calculations" (Baker and Jacobs) just as in a lion's pride. The lionesses work together in every aspect of their life in order to help themselves and also to help the pride. They hunt together, have cubs at the same time and assist one another while raising the cubs. In an all female environment, females become much more social and open while working towards a common goal. However in an all male environment, the males show much more hostility towards one another in group activities because of the competition for dominance. Which is why there are a significantly lower numbers of males in any animals' groupings, the competition for dominance takes over and the good of the group is compromised. Therefore in classrooms modeling the 'ideal' female to male ratio of...

Crocodiles, lizards, fish, and even humans are eaten by a frustrated Bengal tiger. They eat meat and only meat. Their style of attack is differant from the cheetah's and the lion's; who hunt in open habitats. Although it is a heavier predator than that of the lion and cheetah, it averages about 50 deer a year. Bengal tigers need a wide forest-like areas to hunt their prey. They are known to hunt alone, but have been found to hunt in packs. These tigers are semi-nocturnal, because they sometimes hunt at night. They use flying tactics and force their victims by attacking the throat and spine.

...Teenagers are on the cusp of adulthood, but still naive and impulsive. Sure, there are several exceptions to this rule, who are intelligent young people with a great head on their shoulders and know what they should be doing. However, as stated, they are the exception. For analogy purposes, let's look at the lioness and her cubs. She brings the cubs with her on hunts, allows them to stalk the prey and sometimes, even allows them to initiate the kill. She expects them to exhibit adult lion behavior, while never letting them take the full responsibility yet. Why? Because they still don't know what they're doing. They only know what they've learned thus far. She still needs to teach them the finer points of being an adult lion, before they are ready to be treated like one. Human teenagers, like the lion cubs, know what they are supposed to do up to a point, but still require more teaching, guidance and object learning, before they can be treated like adult humans. I'm fairly certain that as you've grown, your mother stopped holding your hand when you crossed the street. She stopped cutting your food up for you. She started letting you dress and clean yourself. These are all steps toward adulthood, requiring you to act in an adult capacity, while still acknowledging that you are a child and still in need of teaching before you can act in full adult capacity. The faster you learn and the more responsibility that you show your parents you can handle, the more they will...

...Lab Report Introduction: Natural selection relies upon the assumption that all organisms produce more offspring than can survive in an environment demonstration limited resources. The heritable traits that are best suited for a particular environment should be passed on at a greater frequency then those less adaptive traits. Natural selection is unique in that it leads to adaptive change, and these changes are likely to lead to increased survival and reproductive success. To sum up, natural selection is that organisms can survive only because they can suit to the changed environment which means those organisms also need to change with the environment all the time. Hypothesis: during the experiment, the forks out of all the “predators” should survive, and the peas out of all those “preys” will be survived. Material and Metnods: We will use 4 kind of beans (preys items) which are fava beans, white beans, red beans and peas. And we also have 4 mouthparts (predators) which are knives, forks, spoons and foreceps. First, we get 100 ml for each prey and spread them on the ground. And the students will be divided into 4 groups with those 4 different predators. Each group of predators include 6 student. And all of the predators will have a cup which will serve as the stomach into which the prey will be placed. We also have a timer and a security that will make sure the process is fair. Here we begin the game. The predators will be gathered, they will be instructed not to...
