| Animal classification 200903992 Yooran Kim On your birthday, I hand you a gift-wrapped box for your birthday present, saying "it is an animal." What would you expect it be? Since there are millions of animals on Earth, it would be easier for you to guess if I give you some hints to categorize the animals. If I say this animal is limbless and lives in the water breathing with gills, you may guess it is a kind of fish. On the other hand, if I say this animal lays eggs and flies the sky with its wings, you may guess it is a kind of bird. Actually there are five types of animals I can get you on this Earth. But I think you may want a warm-blooded flurry animal for your birthday gift that is called a "mammal." Let me introduce three kinds of animals: mammals, birds, and reptiles. To speak about mammals, mammals are the kind we are most familiar with. We human are members of mammal class, too. Mammals characterized by the possession of hair, warm blood, and ability to give birth to live young and produce milk. According to a study, there are about 4,000 kinds of mammals known on Earth. The smallest one is S.minutissimus that is a kind of Sorex, and the biggest one is Balaenoptera musculus whose length is 33m and weigh is 179t. Whales, cats, dogs, pigs, gorillas, elephants, rabbits, hamsters, tigers, and lions are mammals around us. The next class I'd like to introduce is birds. As you can observe birds flying in the sky, they are feathered, and have wings. However, not every bird can fly. There are two types in bird class. The birds that can fly with wings and the other birds that cannot fly even with wings. Penguin is a good example of latter one. Although most bird species can fly, Penguins, ratities, and a number of diverse endemic island species cannot fly. Also, among every bird that has a beak, some birds can mock verbal sign of people do. Some species particularly songbirds and parrots are one of them, and they are popular as pets. Birds are very social animals, so they communicate using visual signals and through calls and songs including cooperative breeding and hunting, flocking, and mobbing of predators. Reptiles are animals that you have seen in the movie "Jurassic Park." Breathing air, laying shelled eggs, and having skin covered in scales and/or scutes are all characteristics of reptiles. Reptiles are aclassically viewed as a cold-blooded. Through the history of evolution, the reptiles took a role of bridge between mammals and birds. Iguanas, Chameleons, Lizards, Snakes, and crocodiles are all in reptile class. Since their skin is covered with scales that keep moisture from leaking outside, they can inhabit dry area such as deserts. Actually modern reptiles inhabit every continent with the exception of Antarctica. So far, I explained three classes of animals that are mammals, birds, and reptiles. Every animal on Earth is related each other but these three have helped a lot each other to evolve. Although there are distinct characteristics on each animal class, we can always find some common features between them. This classification teaches us that we human are a kind of mammals, and really helps us to feel that we are one of animals living on this Earth. |

Yooran, I hope to receive a box named puppy!^^
ReplyDeleteYour main point seems to explain three classes of animals; mammals, birds, and reptiles. It is easy to understand your classification.
But Why mammals, birds, and reptiles? As you mentioned, there are more classes of animals in the world. Are they birthday presents Top3?^^If you explained why you chose these three class, it would be more natural to read for me. Logic!But, Your introduction was interesting:)
Thank you!
Thank you for your reply Yeonyoung, I wanted to explain all five classification, but the book says to do only three: mammals, birds, and reptiles.^^ I thought everyone would knew since the instruction was on the book. Thank you again for your opinion^^

ReplyDeleteFor the last, there is reptile class. Reptiles are animals that you have seen in the movie Jurassic Park. Breathing air, laying shelled eggs, and having skin covered in scales and/or scutes are all characteristics of reptiles. Reptiles are classically viewed as cold-blooded. Through the history of evolution, the reptiles took an important role of bridge between mammals and birds. Iguanas, Chameleons, Lizards, Snakes, and crocodiles are all in reptile class.

Although there are distinct characteristics on each animal class, we can always find some common features among them. This classification teaches us that we human are a kind of mammals, and really helps us to realize that we are one of animals living on this Earth with other creatures.
