How Do Humpback Whales Manage To Migrate

I believe that underwater noise has an effect on marine animals such as whales. Using information from the passages I will prove my point. Their numbers are declining rapidly and I believe that underwater noise has some involvement in the rapid decrease in their population numbers. The information given within the two passages will help prove my point.

The evolutionary path of a whale is a fascinating process of a terrestrial mammal that evolves into a marine mammal. This evolutionary path started with one of the earliest ancestors called “Pakicetus”. A Pakicetus was discovered to be a land animal with four legs that had teeth as carnivores. It skull structure was long, but this organism didn’t look like any marine animal. The scientist then discovered that on the skull’s ear region it was surrounded by a bony wall. This feature on an organism only was distinct from one type of species, scientist discovered that this animal “Pakicetus” was an ancestor of a whale. By comparing the early whales Pakicetus to the next generation of ancestors Ambulocetus, the Ambulocetus whale looks more like

The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.

There is no doubt that humans have always been intrigued with the majestic beauty of the large giants found in all of the world’s oceans. Whales and people have had a long history together, marked by many turns of events.

Textual Evidence: “While the behavior of elephants of elephants provides clear evidence of high intelligence, there has been little definitive experimental evidence. However, one capacity that has been of interest

Ms. Trinh is about to begin a unit on sharks in her fifth-grade class. Some of her students have a strong interest in sharks and know a lot about them. Others know very little about sharks. When Ms. Trinh gives a reading assignment about sharks, she should expect that:

Recent evidence suggests that whales may not have always inhabited the oceans. Bones of an ancient ancestor of modern day whales, the Basilosaurus, were discovered in Pakistan that suggest whales evolved from a wolf-like creature. This genus of an early whale lived 34-40 million years ago in the late Eocene. These fossils show many different features in common with both modern day whales and modern day land mammals. Since the discovery of these bones, many other evidences show that whales are a likely descendant of the Basilosaurus through many different ways, such as embryologic comparison and DNA testing. Whales aren’t the only suspected descendants

By examining, they are too big, they don't get the right care/the whales hurt each other,

Whales resort to pacing around the tank in circles to emulate the fast strong feeling of a swim normally done in the wild in an attempt to keep their dorsal fin upright.

Whales as animals are not easy to track because they move to fast and they live far from the land. Also when they move it is impossible to find any signs of their presence. For many biologist studying whales is challenging and they have tried many complex techniques but without results. Studying these animals with Snotbot sometimes it is inefficient and too expensive.

After reading the three versions of “Whales”, the third version is the strongest. Its thesis statement is the second sentence of the paper: “Scientists studying whales rate their intelligence on a level with higher primates because of their complex group behavior.” The writer also clearly voices their opinion within the piece. The attitude and tone in “Whales” is a perfected mix of professionalism and personal stance, a balance between fact and opinion. The intended audience may be high schoolers in a classroom because of the paper’s writing style. The language and the rhythm of the piece give it strength. Yet there are weaknesses as well. Some ideas I have to revise it so that it is better includes adding more detail to the fast facts and

The first argument is from chapter two. The argument outlines a hypothetical scenario of a spaceship leaving the Earth to visit another planet. The reading then explains how this would be possible by referring to numerous scientific facts, such as Einstein’s theory of relativity. Furthermore, the argument explains that the beings on the spaceship’s destination, less developed than humans today, would be astounded

The Sperm whale is one the largest predators that inhabits the northern, southern hemisphere, and all parts of oceans. The animal can often be found swimming throughout the waters of the Galapagos Islands. It holds the title of being the largest toothed whale, growing an approximate 40-60 feet in length. The animal is also identified by its unique brown and blue-gray skin color. The Sperm whale’s squared shaped head is the most and largest identifiable feature, while containing underwhelming eyes. The name “sperm” whale derives from an organ inside the mammals large head called the spermaceti organ. The Sperm whales uses its unique features to communicate through echolocation by maneuver its way through the ocean to find prey and potential

The humpback whale is one of the largest mammals on the planet. Growing up to 18 meters in length, and weighing between 25 to 50 tonnes they are truly behemoths. The humpback belongs to a group of whales called “baleen” whales. Baleen is a thick bristle like growth that extends from the upper jaw of the whale, such whales do not grow teeth which makes then fairly uncommon among carnivores. The whales spend their summers feeding in the cold southern ocean and migrate north to the south pacific during the winter months.

Whales move a far distance, and the gray whales are the farthest mover. Some whales move between onshore and offshore areas, and the others migrate Iatitudinally (north-south). For instance, the Brazil and New Caledonia whales migrate from low-latitude grounds to high-latitude grounds. In general, whales migrate to cold grounds in summer to feed and move to hot grounds in winter to breed. Whales move straightly. There isn't any evidence which can prove they navigate by the magnetic field
