The Bottle-nosed Dolphin is the most studied and generally the best-known species of dolphin. Bottle-nosed dolphins are classified "Tursiops truncates" in scientific name, and belong to the family Delphinidae, in the suborder Odontoceti, order Cetacea.
This animal is a very intelligent individual. Bottle-nosed dolphins are commonly found in zoos or marine parks because of their capability to perform tricks. They can jump through hoops 5 meters high because of their incredibly powerful tail. As well as jumping, Bottle-nosed dolphins can raise themselves upright out of the water and travel backwards, by threshing their tails.
Bottle-nosed dolphins are generally coastal creatures, occurring along almost all tropical and temperate coasts, although offshore varieties also occur. In addition, the Bottle-nosed dolphin is called the "all-ocean" dolphin, meaning that it lives in every ocean. It is common for a school of 20 dolphins to live together in coastal regions, but school of 200 dolphins are found in the offshore verities. These schools do not seem to have a leader and generally stay together for life.
Such sea life as shrimp, squid, small sharks, other vertebrates and fish are all a part of a Bottle-nosed dolphins diet. When they find a large school of fish, several schools of dolphins join up to form groups of up to 1000 dolphins. They work together to head and catch the fish. Another feeding method the Bottle-nosed dolphin has developed is chasing the fish on to mud banks and snaps them in the air.
Bottle-nosed dolphins are an extremely adaptable mammal. For example, the Atlantic Ocean form tends to be a little smaller and stockier with a shorter rostrum (nose) compared to the Pacific form. In Scottish waters, Bottle-nosed dolphins are chubby with a dark gray complexion, while the in Australian waters, Bottle-nosed dolphins are thin, light gray appearance, with a dominant circle around each eye. The reason why this dolphin may change its physical appearance is because there may be more fish in Scotland, or the prey may be a slower breed, making the Bottle-nosed dolphin not work as hard for its food, therefore creating a chubbier breed of Bottle-nosed dolphin compared to other parts of the world.

A Bottle-nosed dolphin skeletal system is believed to be originated from the basic mammalian skeleton, but has gone through a number of changes. Firstly the forelimbs have been modified into flippers and the bones of the hind limbs have disappeared altogether. Such bones as the rib cage and the spin have also undergone transformation in the fact that they have cured and caved-in due to water pressure. These creatures hold their breath for about 15 minutes before having to submerge for air. The Bottle-nosed dolphin is an amazingly strong creature. Because it never stops swimming, the Bottle-nosed dolphin has a very powerful tail, which is capable of supporting its weight of about 400 kg.
Another factor of a Bottle-nosed dolphins anatomy, which needs mentioning, is its blood circulation. The remarkable feature of this system is its retia mirablilia. This feature is also labelled "wounder nets", which is when the blood vessels create "nets" to protect vital organs form the effects of water pressure.
In conclusion, the Bottle-nosed dolphin has many incredible factors, which make it one of the smartest and elegant mammals in every ocean in the world.
Analysis of "Mirror Self-Recognition in Bottlenose Dolphins: Implications for Comparative Investigations of Highly Dissimilar Species"
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).
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.
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.

They are the second smartest animal in the world. They nurture their young for most of their lives. They also socialise with any creature, unless they show signs of harm. Dolphins make very popular playmates and will come up to humans for almost anything. They rely on each other to live. They learn quickly and communicate well with one another. God designed dolphins with unique physical features and behaviors in order to glorify Him.
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.
The Balaenoptera Musculus, or the blue whale, is the largest animal in the world. Blue
Cetaceans are thought to be some of the most intelligent species on this planet. Popular culture has embraced the idea of cetacean intelligence with shows such as the 1960s hit TV series Flipper, where a dolphin is used to help fight crime. In his comedic science fiction novels, the Hitchhiker’s Guide to the Galaxy, author Douglas Adams suggests that dolphins are the second most intelligent creatures on Earth, behind mice and above humans. Although most scientists would probably argue that humans are the most intelligent species, the behavior and brain size of dolphins and other cetaceans suggests that they too are intelligent. This paper will briefly describe the reason some scientists believe cetaceans are intelligent species and then give examples of scientific studies, which suggest cetacean intelligence. Since bottlenose dolphins and orcas are the most widely studied cetaceans, the survey of field studies will primarily focus on these two species. At the end, this paper provides an argument of why some scientists discredit the high degree of cetacean intelligence.
The article, “A Case of Parenting the Dolphin – Not Tiger mom way,” explains the author’s mother's dolphin parenting style, which does not force to do something and respect children’s autonomy. We read any articles in class, and those articles have opposite theories. I think this parenting style combines other parentings’ good points. Since there are numerous parenting books nowadays, parents are likely to follow the successful theories; however, each parent and children have different character, environment, and relationship. Thus, like dolphin parenting, respecting children's’ autonomy, having not too high expectations, and watching a child grow up with proper distance might be the best parenting style.
The most prominent way dolphins communicate is verbally. There are three different categories that dolphin sounds are divided up into, they are whistles, clicks, and burst pulsed sounds (Herzing, 2014, p.354). Whistles
Whale sharks were named Rhincodon typus by Andrew Smith, in 1828. The naming was hard due to the similarities between the family Ginglymostomatidae and the family Orectolobiformes. The closest relatives to the whale shark are nurse and zebra sharks. The whale shark is the only species in their family, Rhincondontidae. Whale sharks...
Bottlenose dolphins are the best animals because they are highly intelligent, help rescue other animals/humans, and maintain the health of the ecosystem. Contrary to what many expect, dolphins are incredibly smart. Instead of having the survival skills etched into their system, according to research— they are able to learn as individuals, as well as transmit knowledge to others. For instance, Billie the dolphin was rescued from the Patawalonga lock gates near one of Australia's popular beaches in the 1980s.
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).
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
These dolphins are the type of dolphins common people would see at the Zoo or on a T.V. programed performance. Like the Common Dolphins, the Atlantic Bottle-Nosed Dolphins are highly skillful echolocators. They can produce a range of sounds, like a click, using it to analyze any object around them in the ocean (Whitfield 114). According to Whitfield on page 114, they can produce up to 100 clicks a second. They will use these clicks to also find food. They mainly eat Bottom-dwelling fish in inshore waters or surface swimming fish. They can do many other objects with their echolocation finder and using their
