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.…
As a part of the secret merfolk community of Jaffrey’s Cove, Chelsea’s been trying to get the sexy Sheriff Braden Marley to notice her for a long time. 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.…

4. Not all adults feed at a high trophic level. Whale sharks (50 ft) are the largest fish and feed on plankton and small fish, while Great White sharks (20 ft) are the largest carnivorous fish and feed on sea lions, seals and large fish. Blue whales (100 ft) are the largest whale and feed primarily on plankton and krill, while the Sperm whale (45 ft) is the largest carnivorous whale feeding on fish and very large squid.…
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.…
Whales are not fish, but warm-blooded mammals, and have been hunted from earliest times. They were hunted for their oil, meat, bones and other by-products as marine life is a source of food.…
Marine mammals also breathe air, and must come up to the surface of the water to breathe. They have small lungs in relation to their body size compared to humans to reduce problems of nitrogen building up in the blood caused by diving. They have to make sure no water gets into the gas exchange system, and gas exchange must occur efficiently. Marine mammals have to be able to hold their breaths for long periods of time while they are diving. Air enters the lungs through the trachea, which splits into two bronchi and then smaller bronchioles. All of these tubes are held open by rings of cartilage. On the bronchioles are alveoli, where gas exchange takes place. These alveoli greatly increase the surface area:volume ratio, increasing the efficiency of gas exchange and more particles can diffuse at once. The alveoli are surrounded by capillaries so gases can diffuse between the air and blood. Mammals have a circulatory system, so their size isn't limited by their gas exchange system. Because mammals breathe air, unwanted particles sometime get into the gas exchange system. There is mucus in the trachea and bronchioles to keep them clean and moist. The alveoli must stay moist so oxygen can dissolve and then diffuse into the blood. The lungs are also kept moist…
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,…

Man's presence in the eco-system requires a "green" approach to the use of animals. The principle of the sustainable use of a natural, renewable resource meets this requirement ecologically, conservationally and morally” (TheSealFishery.com). I think the seal hunt is one of the world's best examples that refer to “green" approach to the use of a natural, renewable resource because seal hunting is a practice that is conducted safely as well as humanely. Seal hunt is widely practiced in countries across North Atlantic because it is a sustainable and beneficial source of income in those countries. The annual seal hunt is a “multi-million-dollar industry”, first because it offers job opportunities in the areas where there is no any other source…
The extensive list of prey varies but killer whales scout for fish, squid, birds, stingrays, sea otters, other whales, and seal pups. Some, but not all killer whales heave themselves on land to snatch up a meal. Spanish whale hunters in the 1700s named them killer whales because some prey on other whales (“Killer…

Imagine you are gliding through the still blue ocean, surrounded by your family and friends. Suddenly, a loud booming sound breaks through the peaceful underworld. Before you know it, you have been herded into a bay and sealed off from the free world. You watch and wait as others are picked and plucked from the water; they are the “lucky” ones. Next thing you know, a metal rod has pierced your spine, instantly paralysing you but not yet killing you. You are then tied to a boat by your feet and dragged through, struggling for breath and slowing drowning. The last thing you see and feel is a blade slicing through your body, spilling out the contents as you drift into eternal darkness. Shocking as it may be, this becomes a harsh reality for many helpless dolphins swimming the Taiji waters.…
