Tursiops australis, otherwise known as the Burrunan dolphin was recognized in 2011 south-east of Australia by Kate Charlton-Robb and colleagues. The Burrunan dolphin is a type of bottlenose dolphin. There are actually two new distinct species of Tursiops dolphins found in Australia that are under controversy. At one time, all Tursiops dolphins were recognized as belonging to T. truncates. However T. australis, T. truncates and T. aduncus are all distinctly recognized species found around Australia.…

Not only does the stubborn man hold her at a maddening arm’s length, he’s chased away every other man in town leaving her frustrated—dolphin shifters crave sex, and he’s driving her mad with desire.…

Introduction: Every species on this earth has the ability to sense and to survive; and in their own unique way, they communicate with the world around them. Mammals, overall, are able to communicate using vocal signals, body gestures, and chemical signals; more precisely, within the great depths of the seas, there are mammals that are able to use other ways to communicate such as sonar and song. Mammals such as the Orca, Bottle-Nosed Dolphins as well as many other species of dolphins, and different types of Whales are able to use their voices under water to detect and “speak” to other conspecifics. This range can reach distances over miles and miles away, and can also be influenced by the distance at which these different species are from…
Have you ever seen a Spinner Dolphin? The spinner dolphin is a small dolphin found in off-shore tropical waters around the world. It is famous for its acrobatic displays in which it spins along its longitudinal axis as it leaps through the air.…
My name is Jaron Pierre Jr. and i am going to be talking about the sea otter . The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean . They live over 10-15 years . Their breeding season is during September to November , they are territorial during it . Their scientific name is Enhydra lutris . Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb) , making them the heaviest members of the weasel family , but among the smallest marine mammals . Unlike most marine mammals , the sea otter’s primary form of insulation is an exceptionally thick coat of fur , The densest in the animal kingdom . Even though they can walk on land , the sea otter lives mostly in the ocean . The sea otter…
Being the most prevalent dolphin species in the world, the Common Bottlenose Dolphin is widespread, active throughout both temperate and tropical waters worldwide. Despite this extensive range, it does not appear to be present in polar waters (pole-ward 45°) except in southern New Zealand and northern Europe, typically inhabiting waters with a surface temperature between 10 and 32 degrees celsius. The Common Bottlenose Dolphin is one of few species that expoits a wide array of habitats around the world, including both temperate and tropical inshore,…
Usually mammals can only live on land because they can only breathe air. This is another limitation of their gas exchange system. Some mammals have adapted to live in water, but they still have to come up to the surface to breathe air. They can only hold their breaths for a limited time, so must come up to the surface often to…
Introduction: Island of the Blue Dolphins is a very well written book by Scott O’Dell. Island of the Blue Dolphins is a historical fiction. It took place at San Nicolas Island70 miles from the coast, west of Santa Barbara. It’s based on a true story about a 12-year-old girl called Karana who is stranded on an Island and must work out how to survive. Her main enemies on the Island are the wild dogs and she lives in fear of the Aleuts.…
With research and studies being conducted on both wild and captive Killer Whales, data and information has been generated that adds question to the health issues associated with captivity. “The killer whale (Orcinus orca) has proven to be among the most difficult of all species to hold adequately in zoological facilities. The killer whale is a particularly large-brained and long-lived species who evidences a high degree of social complexity in the wild.” (Noonan) Their behavior and relationships with other whales within the family, known as a pod, creates an immense bond between the animals. Whales that were documented inhabiting the Pacific Northwest, remain in their natal group for most, if not all, of their life. (Robeck) When in captivity,…
Keystone species are species of animals that other species and the entire ecosystem depend on. Sea otters and elephants both play major roles in their ecosystems, as they are both keystone species. Without these two species, their ecosystems would have drastic changes in the environment in which many organisms and species would not be able to survive. If the sea otters and elephants were to leave the ecosystem it would cause a domino effect. The domino effect would make other species disappear and become extinct. After species leave, there is room for new species to move in and overtake the native species which would then change the ecosystem entirely to a new one. Sea otters and elephants are prime examples of keystone species, as without them a rapid domino effect would happen…
A lot of beluga whales swim in extreme cold water. Normally they are found in Arctic and Subarctic regions. You can find beluga whales on shores of Russia, Greenland, Canada, Norway, and the United states [Alaska]. Also they have so much blubber that it allows them to swim in the extreme cold waters. Did you know that beluga whales mostly can be located in shallow waters? They are mostly found in waters barely deep enough to cover them, but are also found deep in the ocean, and sometimes found in freshwater rivers. During fall they migrate south to warmer waters and in the spring they migrate back to the arctic ocean to cooler waters. Beluga whales migrate because they can get trapped in ice and become prey to other animals and also for their food supply. Naturally beluga whales are born grey and take 5 years to turn white; they also molt every spring when they migrate to warmer…
Dolphins hunt food in many ways, such as developing a circle around the fish, then diving one after another swallowing their food. There are dolphins that will hit the fish with their tails, which will cause the fish to become unconscious and it will be easier to catch. The baleen whales find food in many ways, such as swimming with their mouth open and gathering food as they swim up to the fish. Baleen whales do not have teeth, so they can eat small fish and swallow their food in one byte. They can chew their food before swallowing it. They can feed on bigger…
Many people want to become involved with marine mammals such as sea otters, dolphins, seals, manatees, or whales. Perhaps such interest has been sparked by Flipper the dolphin on television or Keiko the orca whale in the popular movie, Free Willy. Interest in marine mammals has also been generated by the many underwater movies publicly pleading for protection of endangered whales. Others are just simply scientifically curious. At any rate, there are many reasons for public interest of a career dealing with marine mammals.…
