Mammal

Behavior Although mostly terrestrial, Didelphis virginiana also uses arboreal and aquatic locomotion. On the ground, its gait resembles that of primitive mammals [6], which is unsurprising given that opossum-like mammals first appeared over 65 million years ago around the time when the dinosaurs were going extinct [12]. Though the opossum’s arboreal locomotion is aided by the adaptations mentioned earlier, it is still relatively slow and clumsy. However, it is a strong – if slow – swimmer, and…

The blue whale is a marine mammal. It is the biggest living creature in world. Their veins are so big that a human could swim in them! The heart of a blue is as big as a slug bug! They are not fish because they breathe air and they give birth. The blue whale’s HABITAT is in every ocean. They like to go to the Antarctic Ocean in the summer and MIGRATE north in the winter where it is warmer. Their APPERANCE grayish blue with tiny eyes. Their teeth are called baleen it is the same thing as your…

the grassland in large herds long ago. In the early 1800’s the population of the bison was in the tens of millions. By the end of that century there were fewer than 1000. The bison is a very large land mammal that can grow up to 9 feet tall and 1400 pounds. The bison is the largest land mammal in North America and are very quick on their feet for how big they are. Bisons horns can grow up to 35 inches in length. Bison are herbivores that roam the grasslands in North America. They come from the…

The Giraffe is a large mammal that lives all around africa. They are known for their very long neck and scattered patches of darker hair. They are light brown with large patches of dark colored hair. Giraffes have many natural predators like lions, and other predators. They eat acacia leaves that they can reach with their 6 foot neck. With the 6 foot neck included male Giraffes can't get up to 20 feet tall! Females can get to 15 feet tall. Their lifespan is 25 years in the wild. They are also…

In Immanuel Kant’s “Duties toward Animals, Spirits, and inanimate objects” he makes his stance on animal rights very clear. He believes that we have no direct duties to animals, yet we have indirect duties towards them in order to benefit mankind. Though many philosophers agreed with his way of thinking, many modern day philosophers and scientists are able to find flaws in Kant’s arguments. Kants belief that “we have no duties to animals, plants, material objects, or the environment as a…

whale areas. b) Massive population decline of the killer whales favorite prey—like the great whale—from human influence like over-hunting started a food chain disaster that led to a massive decrease in small marine mammal populations as killer whales moved from marine mammal to marine mammal. c) Whether human or environmental factors, changes in the abundance of sea lions and seals and/or in the food they eat could cause killer whales to have to search for another food source to maintain their…

clashes are natural incidents and they happened not for commercial purposes. Therefore, the argument that mainly whales die because of ships or fishing nets is not the main cause for their deaths. What must be argued is that how these magnificent mammals should be protected by the…

Making a Splash: The Practice of Profiting from Whales Based on what we know today about the effects of holding and breeding whales in captivity for the sole purpose of making a profit, it is no longer acceptable in today’s society to allow this archaic practice to continue at places like SeaWorld under false pretenses. The release of the documentary “Blackfish” has raised questions on the treatment of Orca whales in particular, illustrating the inhumane conditions and treatment of these animals…

encompassed the evolution of arthropods which are ancestors of today's insects and crustaceans, as well as chordates which are animals with rudimentary spinal cords. Vertebrates are a well-known group of animals that includes birds, amphibians mammals, fish, and reptiles. The vertebrates can be well described by their backbone, an anatomical feature that first occurred in the fossil record about 500 million years ago. When scientists describe vertebrate evolution, they most often originate it…

that animals in zoos and especially marine mammal parks have become emotionally unstable due to the conditions they live through in their “homes.” Looking closer to the animals in the marine parks we can see that they are treated poorly because they are needed to increase guest numbers. I have done a lot of prior research on the extremely detrimental stress orca whales have experienced in captivity, specifically at SeaWorld. The captivity of marine mammals was briefly explained in the chapter,…
