The purpose of this paper is to distinguish the differences and similarities of Dolphins and Porpoises. "The term porpoise, whale and dolphin are often used interchangeably, but size (specifically length) is the criterion anatomists have generally used to apply the common name whale" (Dudzinski and Frohoff 2008). The paper will further seeks to identify unique characteristics that dolphins and porpoises possess and the manner in which they utilized these unique abilities to obtain food and survive
The Finless Porpoise 16,306 species of animals are endangered or threatened with extinction. One of these critically endangered animals is the Yangtze finless porpoise (Neophocaena Asiaeorientalis). There are only 1040 finless porpoises in the Yangtze, 13% of these are expected to become extinct within 10 years. When finless porpoises are born the colouring is black, after 6 months turns grey, however there lighter patches around the mouth. Finless porpoises can weigh up to 72kg and 2.27 m in length
Porpoises, belonging to the genus Phocaenidae, are close relatives of dolphins. One of their unique characteristics that differ from other species of the same order is that they can produce clicks for echolocation at frequencies inaudible to humans. The reason for this is majorly influenced by the Orca, also known as the killer whale. Also, while at first glance dolphins and porpoises look of the same species, they actually are classified into two different geni. Part of this separate taxonomy is
Dolphins have long been a creature of great fascination for many humans around the globe and throughout time. They were once completely wild and are now reduced by the hundreds, if not thousands, each year from various events that occur. These events range from being caught for research and used in an aquarium for human entertainment to being trapped and killed for their market value. Any of these occurrences come down to making money. Some of the similarities and differences associated with
particular animal is in fact an harbor porpoise. It is not a baby dolphin! We would like you to go home to spend time with your families and get some sleep, the wildlife specialists will watch the porpoise. We will watch him throughout the night until rehabilitation agency gets here in the morning.” “How did the dolphin get here,” A old lady asked. “It was most likely swimming with it's pod from the bay and got stuck here when the tide went down. Also it’s a harbor porpoise.” Me and my family went home
working on an assignment. The set-up of the skeletons were great, an excellent overall learning environment, very informative and interesting at the same time. The common most popular types of dolphins are; the common dolphin and the Dall’s porpoise dolphin. The two might be so much similar for one to spot a difference easily. This essay highlights the difference between the two species based on the morphological structures. The difference in the common dolphin
The Vaquita is a species of porpoise. Its name means “little cow” in Spanish. Of the several porpoise species that are out there it is actually the smallest. They grow to the size of four to five feet and weigh up to 120 pounds. This rare porpoise species that is fairly unknown to most of the world human population is also the most endangered marine mammal out there and is latterly on the verge of extinction. These porpoises desperately require the human species assistance in order to rebuild its
In the short story “The Sea Devil” by Arthur Gordon, a man is fishing on the still waters of Florida Bay. He casts his net unaware of the lurking danger below. The man liked fishing because of the loneliness and labour. One night the man goes fishing for mullets as he normally does but he catches a mantaray instead. He was pulled in the water by the manta ray and dragged along the waters of Florida Bay. The man was struggling to break free, he was choking on the water and he didn't know if he could
one way or another. Internationally, films that present strong messages about life and the human condition are impacting audiences. The film Muriel’s wedding directed by P. J. Hogan constructs representations of life in the small fictional town of Porpoise Spit in Queensland Australia. The film enhances our understanding of human nature, human society and how we live our lives by making strong statements about the influence of relationships on somebody’s
“The world’s smallest porpoise is slipping closer to extinction…” (Malkin). This porpoise is called a vaquita, and they are being run into extinction because of drift nets set for their larger cousin, called the totoaba. But, this isn’t just happening with these species, it is happening to many species all over the world. A drift net is a large net that is placed underwater for catching fish. Taking all of these fish out of the world’s oceans does not have a positive impact on the ecosystem. Michael
Madison Thomas 7th period 11-30-17 Research Paper Acoustics Acoustics is a science that deals with the study of sound. It is known to be one of the branches of physics; studying oscillations and sound waves from the lowest to high frequencies. Acoustics is known to be one of the oldest sciences, and dates back to ancient times as people had the need to understand the nature of speech and hearing. The main reason acoustics was discovered and is one of the oldest sciences is because of the need
In recent discussions of marine mammals in captivity, particularly the captivity of killer whales, there has been a lot of controversy on whether it is causing harmful effects to the animals. In 2013, a film called Blackfish was released, exposing SeaWorld as treating their orcas inhumanely. SeaWorld, a marine mammal theme park known for its aquatic shows featuring animals such as orcas, has tried to cover up the fact that they do not treat their orcas well, however, people are no longer accepting

Dolphins Dolphins are mammals closely related to whales and porpoises. Dolphins have a powerful and streamlined body. They are found in all seas and oceans. Dolphins can be told apart from porpoises by their nose, which is beaklike, and also their conical teeth. Porpoises have a flatter nose, sharper teeth, and a more solid body. There are 32 known species of dolphins. The bottle-nosed dolphin is often the species used in aquatic shows. The common dolphin inspired many Mediterranean folk lores
forced to return to Porpoise Spit with her mother as she cannot live alone with her disability. Rhonda is extremely bitter in this scene as she believes that Muriel abandoned her to achieve her selfish dream of getting married and finally becoming the new person she always wanted to be. This deals heavily with the theme of identity as Rhonda had believed from the very beginning that Muriel was a success the way she was and that she shouldn’t change herself based on the Porpoise Spit girl’s opinion
The Orca is irrefutably one of the most fascinating animals in the ocean. Killer whales, or Orca, are aquatic mammals which live in almost every ocean on Earth. Their black and white color pattern makes them one of the most easily recognized animals on Earth, and their intelligence and strength makes them apex predators. Though the killer whale sounds like an aggressive animal, Orcas are very social and are very sensible in what they kill. Though the common name of the Orca is “killer whale” or
Although whales spend their lives in the sea, they are, like humans, warm-blooded mammals. After a baby whale is born, it nurses on its mother's milk, just like the young of land mammals. Whales are members of the order Cetacea, along with dolphins, porpoises, and the narwhal. There are two basic types of living cetaceans: baleen, or whalebone, whales of the scientific suborder Mysticeti; and toothed whales of the suborder Odontoceti. General Characteristics Whales live in all of the open seas of
My evidence for evolutions is how hippos have adapted to dominate by gaining helpful traits and evolving new ones. You’re probably thinking that hippos are a very dangerous and hurtful animal, which is true, but they are very important in their ecosystem and have evolved from many various animals to be the wonderful yet dangerous beasts they are today. The hippopotamus is a herbivorous mammal that inhabits in the rivers south of the Sahara Desert. Most hippopotamuses are highly ranked to be one of
Birth in the Dawn vs. The World on the Turtle’s Back “Birth in the Dawn” and the “World on the Turtle’s Back” are stories about the creation of Earth and how it became what it is with all the animals and plants. These stories have different ideas of how the world came to be, but both have creativity. They may seem a tad astonishing, but the people who created them clearly believed them. “The World on the Turtle’s Back” is an interesting story. “The World on the Turtle’s Back” tells a story of the
