Introduction The bottlenose dolphin is also known as Tursiops truncatus. It’s the adorable mammals whose mouth somehow appears to be curved in a friendly smile that invites people to come and swim with them and watch them perform complex tricks. They weigh around eleven hundred pounds and can be anywhere between ten and fourteen feet long. These creatures can swim around eighteen miles per hour and often travel in large social groups. They can live up to fifty years and most are found in the tropical oceans and others can be found in warm water all over the globe. Tursiops truncatus are a higher-order predator that is often referred to as “ocean sentinels of health.” Starting July the first of 2013 these Tursiops truncatus were dying in unusually large numbers all down the east coast. Facts show that in the month of July the average numbers of these animals that usually wash upon shore are just around six or seven in Virginia and thirty-six in all the states between New York and Florida. Starting up north in the month of July ninety-one died in New York. Sixty-three died in New Jersey, twenty-seven in Maryland and forty-one in Delaware. In Virginia around one hundred and seventy-four had been found and seventy-eight of them washed up on shore. Virginia had a bigger number of deaths thought to be because we have more suitable habitat, we have more coastline. In that summer the Virginia Aquarium and Marine Science Center had found and examined 44 deaths, than that following week the same aquarium confirmed that an additional 13 dead Tursiops truncatus were found over the weekend. 333 Tursiops truncatus had washed up dead on beaches from New York to North Carolina by August 26, 2013.

Right now, experts think this outbreak is probably due to "herd immunity." That’s when Tursiops truncatus that survived the 1987-88 Morbillivirus outbreak carry antibodies to the virus which protects them against the virus. These protected individuals also help protect new or young Tursiops truncatus without natural immunity, since these unprotected individuals have less chance of contracting the virus. Sadly eventually, those virus-resistant Tursiops truncatus will die or leave, and then the whole population becomes immured. Studies have shown that Tursiops truncatus younger than 26 years have limited to no immunity to this virus. So if this virus is now revealed, they don't have the initial antibodies to protect them from this deadly illness.
One of the most common dolphins that are found in southern California is the bottlenose dolphin (Kelly). The bottlenose dolphin is mainly found in coastal waters between 45 degrees north and 45 degrees south, also in Northern Europe waters. It is believed that there are two types of bottlenose dolphin regional wise: oceanic form and coastal form. This species is studied the most by biologists (Jefferson). The coastal population lives in fairly open groups with twenty or less in a pod, some groups are found to contain more in open ocean. It is not uncommon for these species to interact and breed with other species, as would a human interact with other diverse humans. The dolphins feeding behavior is adapted to the availability of resources. They sometimes are known to work together to catch fish from large schools, they also trail behind large fishing boats to catch what falls behind (Leatherwood).
Almost no one on Earth has any immunity at all to this virus, which makes ordinary vaccines useless against it. The sudden spread of the virus into Europe foreshadows an epidemic development that could be worldwide. Ultimately, there is no way to protect ourselves against epidemics. They will keep disappearing and coming back in new forms.
Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.
Discovery of this virus divided scientist in two groups; the ones in favor of publication the virus and the ones are against the publication. According to Fouchier in the article “The Deadliest Virus” by Micheal Green, he says that if more people have access to it, it
Orca whales are the largest members of the dolphin family. Orcas are very curious creatures, they like to sky hop, which is when they poke their heads out of the water and look around, and they can also dive to as much as a hundred feet. These social animals live in pods and stay with them for their whole lives. They are so family oriented that they can may sleep together in a tight circle and have synchronized breathing. Orcas can grow up to thirty-two feet and can weigh nine tons. They typically eat five percent of their body weight and are amazing hunters. The lifespan of an orca in their natural habitat is about fifty years. This lifestyle for them is wonderful because they can swim as far as they want to and are free. Orcas should not be held captive because the capture process is dangerous, it is not good for their health, and their trainers are at risk. Free Willy. Dir Simon Wincer. 1993.Video.

A bottlenose dolphin, Tursiops truncates, has a streamlined body. A dolphin's outer skin layer (epidermis) is about 10 to 20 times thicker than the...
Bottlenose dolphins became part of a United States Navy program in 1959 for the purpose of conducting scientific research into their sonar and hydrodynamics in hopes of getting design ideas for submarines, ship hulls and weapons. It was discovered dolphins hear and navigate in the water by using their natural sonar, which happened to be more precise than most fabricated sonar systems. In the mid-sixties, Navy dolphins were used as mail carriers to underwater laboratories in their home of San Diego, California.
Commercial fishing of other marine animals is one of the main reasons for drastic decline in all sea turtles. Turtles rely on air to breathe despite being marine animals, therefore when captured in nets while scavenging for food they most likely drown. In the US alone 250,000 turtles are accidently captured, injured or killed every year. (WWF, conserveturtles) However, there is also commercial fishing within sea turtles. Turtle’s shells, skin, meat and, eggs are valuable and decorative items that many humans want to
In the books Hatchet, Guts, and Island of the Blue Dolphins the characters all go through horrifying experiences. In Hatchet, a boy named Brian is forced to fly a plane after the pilot dies of a heart attack. In Island of the Blue Dolphins, a girl named Karana and her brother were left behind by their clan. In Guts, a man named Gary Paulsen answers emergency ambulance calls and witnesses many deaths from people.

Orcas, or killer whales are majestic giants of the sea. They are actually the largest type of dolphin. They have long black bodies with distinct white patches near their eyes. A killer whale can be up to 32 feet or more in length, and weigh up to 12,000 pounds. Females are a bit smaller, but live longer (Gorman). The name “killer whale” apparently came not because it is a vicious whale, but because it preys on whales. They do not have any natural predators, and they are considered the “top dog” of the ocean. Not even the great white shark stands a chance against these superb killers. “Unlike sharks, killer whales are cautious hunters, sometimes spending hours harassing a 1,000-pound sea lion so it can easily be drowned” (Francis). Orcas use many hunting tactics that are unique to their species, which is what makes them invincible.
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).
Humpback whales are amazing mammals and they go through a lot of extraordinary things to be able to survive. There are many whales in the ocean, but the whales that are in the Hawaiian culture areas have many difficulties and most people don't understand why.
Dolphins are well known for their agility and playful behavior in the wildlife of all the oceans in the world. They have many characteristics, and also there are a variety of different types and kinds of dolphins, which make them very intelligent creatures. Dolphins are smart marine mammals and great swimmers. They are known to be very friendly to humans and other wildlife creatures, dolphins often display a playful attitude which makes them popular to human nature and the culture. They can be seen jumping out of the water,riding waves, play fighting and occasionally interacting with people swimming in the water. Dolphins love hanging along the sea shores of all beaches around the coast, where it is warm and tropical(Fun dolphin facts).Dolphins are believed to be the most intelligent animals on earth
Did you know in the world there are more than 90 species of whales, dolphins, and porpoises? (WDC) The dolphin is a very important animal to the ocean and there are many different types to discover. In order to learn about dolphins, it is important to discuss where they live, their appearance, and what they eat. Some helpful words to understand are “dorsal fin”, a dorsal fin is the top pointed fin on the dolphins back, “flippers”, a flipper is a flat fin that dolphins use to swim, and “echolocation” is a tool dolphins use to find food by sounds bouncing off of objects (dictionary.com).
