Types of Animals on Earth Essay

While domesticated pets like dogs and cats make good pets many people want to own exotic animals that belong in the wild. These animals range from tigers to pythons, but should not be owned as they need special care most people cannot provide. Not only this, but exotic animals release is harmful for everyone, the exotic animal, humans, and native animals. Lastly, many exotic animals carry diseases that are harmless to them, but fatal to humans. Exotic “pets” are harmful for everyone, not just the pet. This is why people should not be able to own exotic pets.

Every child has asked their parents for a pet animal. The thing is though, is what type of animal they asked for. Such as a dog or cat and even the occasional hippopotamus for Christmas, right? Lots of people buy exotic animals not knowing how much work it really takes to take care of them. For example, many people have bought pythons and when they get to a size where they can’t keep care of them they let them go into the wild. Exotic animals are very costly and time consuming, they grow up and get bigger and all in all they are very dangerous.

There are four main groups of reptiles, known as Crocodilians, Squamates, Tuataras, and Turtles. Crocodilians consists of large reptiles which includes alligators, crocodiles, gharials, and caimans. Squamates are lizards, snakes, and worm-lizards. A worm-lizard is a subterranean burrowing reptile that resembles an earthworm, a legless lizard. Tuataras are a group of reptiles that are lizard-like in appearance but are different from squamates because their skull isn’t jointed. Turtles are the most ancient reptiles alive today. They have changed very little since they first showed up 220 million years ago. The first turtle appeared 220 million years ago.(Laura Klappenbach)

All mammals have hair and mammary glands which is what separates the group from others. However most modern mammals are also distinguished by a single dentary bone, the mandible, and most have two or more types of teeth. Also, most mammals have sweat glands.

Bandit was a hybrid half wolf and half dog, he was used for entertainment at a golf course and was abused by an angry man because Bandit tried stealing one of the mans golf balls. The man beat him with his golf club and Bandit suffered from a broken shoulder and now is scared of people. We should be able to own exotic animals for endangered reasons. If an exotic animal is kept in captivity they can be breed and make the population bigger. Exotic animals are also so great for people who have allergies, we can build special bonds with these animals

Mammalia is when young have milk from their mother, and they give birth and not lay eggs.

Mary Anning’s contribution to the development of the understanding of how reptiles contributed to evolution and to the understanding of fossils as extinct life forms was important.

There are many exotic animals all over the world that live in the wild. There are many species and some are extinct. Exotic animals are very expensive that require more than what people realize. These animals belong in their natural habitats. It is wrong and cruel for the animals that have to live in captivity when they are meant to live in the wild. Taking exotic animals out of the wild disrupts the natural food chain and negatively affects natural selection.

The earth is so far the known planet to sustain life. Starting as small dense group, humans have populated the earth to where they the most populated species on earth. When humans first populated the earth, they did not live long lives. Disease, animals, and natural disasters made life on earth a nightmare. As humans

There are 6.5 million species of land mammals. Wildlife biologists get the privilege of studying and spending time with these animals as their everyday life. I should be a wildlife biologist so I can study land mammals.

There have been five well known extinctions on this earth. The one most well known is the mass extinction that ended the dinosaurs. Mass extinction is often described as the elimination of a large number of species in a short period of time. Despite what many think, the elimination of species is almost commonplace at this point. The Earth is currently in the middle of a sixth mass extinction, and it’s been caused by the human race.

Over 98% of all organisms that have lived on Earth are now extinct. A mass extinction event occurs when a large number of species die out within a small time frame (relative to the age of Earth). Mass extinctions are intensively studied for both cause and effect, as there is usually room for debate regarding catalysts that precede the extinction and the massive influx of new biological species that follows. There have been five major mass extinctions, dubbed the “Big Five,” that have wiped out at least 50% of the species living at those times. The most well known mass extinction of the Big Five, with the decimation of every species of non-avian dinosaur, is the Cretaceous-Paleogene

Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists?

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
