General classifications: Bottlenose dolphins are the most common and well known members of the dolphin family. They are mammals and their scientific name is Tursiops Truncatus. They can be found in pods (which means a group of dolphins) and extremely few are found alone. These dolphins are also part of the Delphinidae family which means dolphins in Greek. Appearance: Bottlenose dolphins are known to be two to four meters long and their average weight is between 150 to 200kg. The dolphin’s snout is short and rounded at the top which gives it its name- as it is like a bottle. The dolphins have many shades of grey skin but white on their underside. Bottlenose dolphins use their two side flippers to steer through strong currents and to make tight turns. Their tail is called a fluke and is used to push the dolphins through the water and gives it its speed. The top fin is called a dorsal fin and is used to help the dolphin balance and in fact it is not needed - so dolphins could survive without a dorsal fin. A dolphin can have between 18 to 26 teeth which are used for grasping their food. A dolphin has its snout at the middle of the head, one eye on each side of their head and a blowhole at the top, which is how they breathe. Dolphins do not have gills. …show more content…
Bottlenose dolphins find their food in a pod in a way that is very smart for an animal. In their pod they round a school of fish by circling around them and one by on going into the fish grabbing one and they continue this. If they continue this they will all get a good amount of food for them to eat. As well as these foods sometimes bottlenoses eat crabs and other small
Unlike most other whales, Narwhals have no dorsal fin, instead they have a low bumpy ridge that begins at about the midpoint of the back and continues to the fluke#. Tusks The tusks, giving Narwhals the name, “Sea Unicorn”, is actually a tooth that can reach up to nine feet long and can weigh up to 20 pounds. Males and females are born with two teeth pointing forward in the upper jaw. The left tooth of the male grows long and spirals counter clockwise toward the tip.
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 Humpback whale (Latin Megaptera novaeangliae) is a mammal, which belongs to the rorqual family.
...own to circle its dead for hours until dying itself. It puts its own life on the line when the others in its group is in trouble. The diverse diet also makes it an interesting marine mammal to know about because different types of marine life have a food staple consisting of two or three species. The orcas distinctive white spot above the eye make for good diversion and the conical teeth make for excellent hunting. And although they range in size depending on sex, the fascination with this fair sized marine mammal is immeasurable in size.
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.
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.
they look at the dorsal fin. Each pod of whales has its own individual type of dorsal fin. In some
The purpose of this paper is to distinguish the differences and similarities of Dolphins and Porpoises. "The term porpoise, whale and dolphin are often used interchangeably, but size (specifically length) is the criterion anatomists have generally used to apply the common name whale" (Dudzinski and Frohoff 2008). The paper will further seeks to identify unique characteristics that dolphins and porpoises possess and the manner in which they utilized these unique abilities to obtain food and survive in oceanic waters. Provided are also information in relation to dolphins and porpoises method of communication, description, intelligence and reproduction.
Many people can feel connected to the earth and their surroundings by observing and learning the way of the animals, including the whales. The Bowhead whale has been an important part in the Inuit-Inupiaq people of northern Alaska’s way of living. Native Americans have used animals like the whale in their stories to explain life and moral values. An American Indian author, Vine Deloria Jr., stated that, “Native Americans saw themselves as being related in some fundamental manner to every other living species. They believed each species had a particular knowledge of the universe and specific skills for living in it.” (Caduto and Bruchax, XI) Vine Deloria along with many other Native American authors has taught us through their words the roles that animals play in the Native American culture. The animals in these stories teach us some of the same values that are displayed in traditional literature, including fairy tales, nursery rhymes and The Bible. We can see how Bowhead whales’ physical traits and connection to the earth are linked to Native American culture by examining scientific information and Native American literature.
One hundred percent of male orcas, and even a few females, in captivity posses a collapsed dorsal (top) fin; they are not born like this. Over time, this collagen appendage may flop over or collapse from lack of use (Cowperthwaite). Whales in captivity often swim in the same direction for long periods of time, limiting the necessity for a strong dorsal fin. Though the majority of whales in their care suffer from this problem, SeaWorld claims that this occurs naturally in 1 in 4 of all orcas (Killer Whale Care). Dorsal collapse has not been reported in wild orca populations (Cowperthwaite).
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...
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
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).
