Have you ever seen the dolphin show at Miami aquarium, or SeaWorld? Those charismatic and energetic dolphins are bottle nose dolphins. They are very smart and obedient creatures that can be trained in captivity: however, in the wild they live in schools. In this paper I will be explaining the Habitat in which the bottlenose dolphin lives, how they adapt in the wild, and unique things about them. First of all the Bottlenose Dolphin is From the Animalia Kingdom, Phylum: Chordata, Class: Mammalia, Order: Cetartiodactyla, Family: Delphiniae, And Genus Turiops. Bottlenose Dolphins have a life span on average of 20 to 40 years. They can be found anywhere from the coastal water to the open ocean. From temperatures of 10°-32°C or 50°-90°F. From the …show more content…
The body is streamlined body that helps them glide through the water faster. The bottle nose dolphin has pectoral flipper measuring from 12- 20in and are used to help them steer threw the water. Bottlenose dolphin’s auditory cortex of the brain is about twice the size of a humans. Their hearing range in frequency is up to 160 kHz. Bottle nose dolphins Diving is amazing for their survival when Hunting for food they can dive deep down as far was 2,300 feet and can hold their breath for as long as 12 to 15 minutes. They also use Echolocation kind of like sonar to find their prey. The dolphin starts by making clicking noises that reach Animals and objects making it easy to locate prey and other predators in the environment. Dolphins also use counter shading the body is gray to dark on their back and white on the bottom to help them blend and hide from predators and to sneak up on prey. The major Predators to dolphins are Large sharks example being tiger sharks and bull sharks are on rare occasions Killer Whales and Stingrays with sting rays being very rare only cause trauma and poison or infection from wounds.. Although it’s not uncommon to see dolphins with scars from shark bites on
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.

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).
The proposal of eliminating dolphin hunting serves to achieve important concepts that people should have. The biggest drawback of dolphin hunting is the massacre. Slaughtering dolphins are blatantly immoral, especially in the brutal way Taiji hunters did. Unlike livestock, dolphins are not artificially bred and raised. They are born and beloved by their parents and also their pods. In addition, they are free-living animals that are not meant to be killed by humans. People have no rights to ruin their lives because people didn’t benefit them anyways. Furthermore, dolphins, unlike fish, have feelings, meaning that they can feel the pain when they are butchered and when they see their loved ones slain (Carpenter).
Now. I will tell you about dolphins and killer whales traits. First, let me start off by their both mammals. Dolphins and killer whales live in a pod, as well as they’re both carnivores. Although they both have dorsal fins, dolphins have a round dorsal fin, while on the other hand, killer whales have tall, wide dorsal fins. Now, let’s talk about their color of skin,dolphins have striped skin, and killer whales have black and white markings on their skin. Although, dolphins and killer whales are gorgeous animals, they are becoming threatened and endangered.
The reason baby Gore Ottsen survived is due to a evolutionary reflex called the mammalian diving reflex. This reflex is found in mammals such as dolphins and whales who cannot breathe underwater. These animals must come up to the surface to breathe and then carry their air with them as they swim. For example, sperm whales are able to dive deeper than 1000 meters and store up to 3000 liters of air before a dive. How can a mammal stay underwater for so long? Similar to baby Gore Ottsen, the mammalian diving reflex allowing them to stay submerged for extended periods of time.
Sea lions may look like sea creatures, but they also behave like terrestrial animals. Unlike whales, mammals that spend their entire lives in water, sea lions inhabit both the water and land throughout their lives. This aquatic land animal prefers the water for food, fun, and safety; while preferring the land for socializing, territory, and procreation. Being mammals, they share many behaviors common to humans and other mammals. Like mammals, they are born with the ability to walk on land shortly after birth. Surprisingly, they are not born with the ability to swim from birth, but need to be taught by their mothers. Like other mammals, they love to stay in social groups. During their reproductive season, females are dominated by aggressive males, that establish harems on the beaches. The relationship between females and their pups is characterized by affection, protection, nourishment, and instruction. In contrast to their limited terrestrial mobility, they can swim much better than they can walk. Unlike other land mammals, they have the ability to sleep in water . The most interesting thing is that they can sleep in water by using one part of their brain, while the other part of their brain is asleep ("Birds sleep with one eye open, half awake, study finds"). Clearly, sea lions have adapted well to a both an aquatic and land life.
Within the essay written by Bill Daly called “Marine Parks” the writer is trying to provide information to his readers about marine parks. Daly takes the stands and conclusion on that the parks should be closed or at the very least they shouldn’t capture anymore animals. In the essay he discusses that the information that they take from the dolphins isn’t credible information. Due to the fact they are only studying captive animals not the one in the wild. He goes on to tell about how they have different diets and in captivity and that they have lower life spans.
A Humpback whale is a large Dark grey mammal with white patches on their stomach and knobs (known as tubercles) covering their head. They can range in size from 48 to 62.5 feet and can weigh from 25 to 40 tons. Newborns can weigh about 1 ton. Did you know that the largest whale ever recorded was 89 feet, that’s longer than a school bus. Humpback whales are vertebrates just like every other mammal. They got their common name
Humpback whales have the scientific name of Megaptera Novaeangliae, that species of baleen whale is one of the larger species, and adults range in length from twelve to sixteen metres which is thirty to fifty-two feet. They weigh approximately seventy-nine thousand lbs (pounds), and they have a distinctive body shape. These whales get their name from the way they come up for air and show their back dorsal fin. this happens right before it starts moving its flukes, flukes are the tail fins. Lots of people first identify a whale by it flukes. (which is another name for its tail fins). they say humpback in their name but the hump they see is actually a forty-nine feet of back rolling into a sixty-thousand pound plunge into the water. “Its most likely that humpbacks sing to communicate with other whales and to attract potential mates, National Geographic,page6”. Humpback whales grow strange things on their body like hair, these large mammals have whiskers like cats and other animals.the first thing people see is the bump that the hair grows on. Scientist say that they have these to feel things like cat’s and other creatures do.Another interesting fact about this animal is that scientists found out the age of beached whales and ones that have been killed. Marine biologists can determine the age of these whales by their teeth. When they find a dead whale or kill a whale, Marine biologists can also look inside the ear and look at the different layers of ear wax ty...
Schaefer, Larry. "Dolphin Web Site."Http://understanddolphins.tripod.com/dolphins.html. N.p., n.d. Web. 14 Sept. 2016. This image displays homeostasis because dolphins are abel to thermo-regulate, the ability to control body tempature. One of the ways dolphins thermo-regulate is during dives, the outer portion of a dolphins body reduces blood circulation and consentrates blood circulation into the core organs and tissue. This pevents heat being released into the enviorment because the heat is being transfered from one blood vessel to the other. Some other ways dolphins body's thermo-regulate is bluber insulation, also dorsal fins and flukes release heat. Mainting a homeostais body tempature is so signifigant because without thermo-regulation
Dolphins had a prominent role in Greek mythology as well. One of the first dolphin stories is Homer’s ‘Hymn to Apollo.’27 The story tells the tale of the god Apollo’s founding of the temple at Delphi.28 Apollo had searched all over Greece to find a suitable site for the temple and finally settled upon a deserted cave that was guarded by a dragoness.29 After killing the dragoness, Apollo hijacked a Cretan merchant ship in the guise of a dolphin.30 The dolphin Apollo guided the ship to Delphi and instructed those aboard the ship to live in his temple, serving as priests.31 Apollo also instructed the men to “pray to me as Apollo Delphinius.”32 Poseidon, the sea god, was also strongly associated with dolphins. One myth details how dolphin messengers
A lifespan of a dolphin is 20 to 90 years. When they get pregnant that last about 10 to 12 months. After a calf is born it will swim to the surface to get its first breath of air.
The common bottlenose dolphin is arguably the most popular species of the Delphinidae family. Because they are found in both temperate and tropical waters, they are the most studied species; a majority of our Physiology knowledge about Delphinids as a family is based on bottlenose dolphins (Cozzi 2016). Because of the wide variety of habitats and climates that bottlenose dolphins inhabit, there is a lot of debate about how many different species are encompassed under the Tursiops Truncatus classification. However, in 1998, Tursiops Aduncus, commonly known as the “Indian-Ocean bottlenose dolphins”, was recognized as a separate species (Rice 1998).
Earth's climate is changing, it is possible at an unprecedented rate. Overall, the earth is warming, sea ice and glaciers retreat, sea level rise, as well as pollutants accumulate in the environment and in vivo. These clear physical change will undoubtedly affect marine ecosystems. This research is talking about the important of dolphin in the ecosystem, causes of dolphin being threatened to extinction and the discussion about the way to protect dolphin.
