Delphinapterus Leucas, also known as Beluga Whales, are white whales that live in arctic waters. They are friendly whales that enjoy vocalizing or making noises. These noises are used to communicate, and use them for echolocation. Beluga Whales do not posses vocal chords and are suspected of using the air between nasal sacs in the blowhole region. They have small but distinct beaks.
Keeping these huge animals in small pools does not seem right. Big mammals are not meant to be in small pools. When these mammals are born they stay with there mother all of their lives. They never leave their mothers until they are captured and put in small pools which is not right. Killer whales hunt in pods, the oldest female in the pod is usually the group leader. Each pod has its own set of whistles, clicks, and calls that only members of the pod recognize similar to having a unique language. Members of many pods hunt in teams. For example, they may work together to create waves to knock a seal from an ice floe and into the open water. In many pods,...
This has been a tradition of the Makah Indians for more than 2000 years. They had to stop in 1926 due to the scarcity of gray whales. But their abundance now makes it possible to resume their ancient practice of the hunt.
Narwhals Introduction Narwhals, the unicorns of the sea, are very mysterious creatures that are not widely known. They are whales with many fascinating features and historical value. This research paper answers the question, “What are Narwhals?”. General Description Monodon Monoceros, Latin for “one tooth, one horn”#; or Narhval, Norwegian for “corpse whale”, because its mottled coloration suggests a bloated corpse#. Narwhals are in the white whale family, along with the beluga, but are actually covered with spots of black, white, gray-green, and cream.
Cane toads originated from South America, were introduced to Australia in the early 20th century and have been in Australia for nearly 70 years. Cane toads were relocated by the Europeans to control destructive beetles that destroyed sugarcane in Cairns approximately 2900 young toads were released in Australia, after a while the group of Europeans discovered cane toads were unsuccessful at removing the cane bugs. Cane toads spread throughout Queensland, Cane toads have spread south and west and now cane toads can be found in Queensland, Northern Territory, New South Wales. Cane toads became were well known as an invasive species or pest. Cane toads eat bugs, ants, generally anything that could fit inside its mouth, most cane toads grow to 10-15cm long and females have been grown to 23cm colour ranges from grey to olive brown. They breed in slow moving water, females lay about 8- 35000 eggs a
If puffins are disturbed by humans they will leave their nests and will not come back. This has led to the extinction of puffin colonies in parts of the European coastline.

Today, in addition to the bottlenose dolphins, the Navy program includes sea lions and white beluga whales. The sea lions have excellent hearing and can dive much deeper than dolphins. They are trained for marking mines and retrieving torpedoes or practice mines, all while being more efficient than human divers. The white beluga whales dive deeper than the sea lions to recover inert torpedoes and are currently on loan from Sea World.
The blue whale and its relatives are called baleen whales because they have a feeding structure known as baleen that takes the place of teeth. Baleen is made of a flexible material containing a protein called keratin, which is also found in your fingernails and in the hooves of horses and cows. Baleen plates hang down from the roof of the whale's mouth in rows, somewhat like the teeth of a comb. The inner edges of the baleen plates are fringed and look hairy.
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.
After watching several documentaries on how poorly killer whales are treated in captivity, it drew me into researching more information on the treatment of Killer whales that are kept in captivity. I found several scientific journals, and articles on wild life facts of killer whales and I found published books on the treatment of killer whales in captivity. The information I found includes both wild killer whales and killer whales kept in captivity. With the information I found, I plan to prove the shortened lifespan and health problems killer whales get while living in captivity are not normal. In fact the information you learned about killer whales from aquariums and commercial parks are false. This paper will argue why killer whales should not be held captive in commercial parks. This Paper will include information on the killer whale’s diet, the killer whale’s communication, and the killer whale’s physical traits.
In the world today, we know that whales are majestic creatures with amazing lifestyles that we don’t completely understand. We also know that however large they are, they are in danger because they have been over hunted and over used by human beings. Today through Commercial Whaling, the whales of the oceans have been put at risk and their population continues to decrease. Countries such as Japan, Iceland, and Norway defy the rules set by The International Whaling Commission under the pretense that they’re whaling for scientific reasons, when in reality they are whaling for commercial reasons of profit. Commercial whaling is a problem in countries around the world, most prominent are the Japanese, and other countries are Iceland and Norway. Over time the status of the whale population has declined because of the increase of technology in whale hunting.
Killer whales communicate by a series of clicks and whistles called vocalization. Each pod, or family, has their own unique language. This gives whales the ability to identify their own pods. Orcas have a brain that is about five ti...
During the month of September in 1998 an amazing and unique discovery was found by a group of scientists when they went out to the Sea of Japan. There, they collected the carcass of a medium sized baleen whale. This was the ninth specimen needed to complete the research on discovering this new species. This species of the baleen whale did resemble the fin whale, another species of the baleen whale. However, this carcass was much smaller in size. After comparing DNA data of the external morphology, osteology, and mitochondrial, scientists were able to classify all they found into a new and different species. This new species, which was named after a Japanese cetologist, H. Omura, has a unique cranial morphology and a small number of baleen plates. Another wonderful discovery was made while doing this research as well, that was that one of the species of baleen whale could actually be classified into two unique species, Eden’s whale and Bryde’s whale. There were thought to be only five species of the baleen whale. But after the new discovery was made the number had risen to eight.

The Humpback Whale, Megaptera novaeangliae, is part of the marine mammals group. They are found in oceans all over the world, they live in open waters. Even though they are mammals, they do not live on land (Monterey Bay Aquarium). Humpback whales are known for their magical song that can travel great distances. These gentle giants are omnivores, their main diet is krill. They are mostly found near coastlines feeding on tiny shrimp-like krill, plankton and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding water closer to the Equator. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke to propel themselves through or even out of the water! Mothers and their young swim close together, often touching one another with their flippers with what appears to be gestures of affection. Even though it takes more than one year for a humpback whale to grow fully, mother whales leave them after one year (National Geographic).
