Their flippers are compacted and are spiraled and circumnavigated at the extremity.Their tails are carved at the midpoint. They move in pods of 2-40 dolphins in a group. HABITAT …show more content…
They like to be in deep water that is offshore in 43 to 62 degrees fahrenheit. When in cold water, they travel to inshore waters. They live from Aleutian from Alaska to the tip of Baja california in the eastern pacific ocean. ADAPTATIONS the dolphins have a dark gray or they can have a black back. A white belly and a distinguishing white or gray striped (on both of their sides)- called countershading.The dark back of the pacific white sided dolphin helps them to mingle in with the ocean and safeguard themselves from predators. The white on the other hand, conceals it when ogled from beneath, opposed to light from the sky. population and human
Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.
Dolphins make up the largest and most diverse family of cetaceans. The family contains 26 recognized species of which 13 tend to have long well defined beaks and streamlined robust bodies. Many vary in size, shape, colors, beaks and flippers, as humans have various characteristics.
If you think you've seen one dolphin swim you've seen them all, Jason found one that promised to be different. He headed 5km off-shore to where the dolphins take you right into their world as you swim with the pod, the only place in New South Wales you can do that.
not travel into deep ocean waters. They like calm, quiet waters to relax and eat.
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).
Orcinus orca is the scientific name for the massive marine mammal. Orcas are not rare, but have declining numbers in some areas (Martin.) Orcas are found from the Artic Ocean to the Antartic Ocean. (Britannica) They belong to the Delphinidae, or dolphin family, which is the largest of their species. Female orcas grow to be at the most 15 feet, and weigh up to 4 tons, but the males can grow as large as 20-30 feet, and weight up to 8 tons. (Martin) The color of the orca is white in some spots, black on the majority of the body, and gray just behind the dorsal fin. It is white on the chin, belly and the eye. The white patch above the eye is usually mistaken for the eye, and may confuse their prey, but acts as a camouflage for the eye. The name “killer whale” makes people tend to believe that this is a viscious man-eating mammal, yet it is one of the most shrewd, docile and playful species of the marine mammals. The orca is sexually mature at 10-15 years of age, much like humans, which is 12-13 years of age. They tend to mate year round, and is able to have a calf every two years. It is interesting to know that lactation of the mother lasts 12 or more months (Wynne.) The life expectancy of orcas is 45-50 years of age.
Harbor seals are marine mammals that have spotted coats in a variety of shades from silver gray, black to dark brown. They reach 5 to 6 feet in length and weigh up to 300 pounds. Harbor seals are dimorphic, with the male being slightly larger than the female. They are true, or crawling seals, which means they have no external earflaps. True seals also have small flippers, and move on land by flopping along on their bellies. They breathe at the surface and hold their breath while diving. They can dive to 1,500 feet for up to 40 minutes, although their average dive lasts 3 to 7 minutes. Their scientific name basically means 'sea calf' or 'sea dog.' This nickname is fits them well, as these seals closely resemble a dog when their head is viewed at the surface of the water.
Narwhals are an odd type of mammal as they are whales. Most whales don't have a protruding canine tooth. The narwhals taxonomy consists of: Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Cetacea, Family Monodontidae, Genus Monodon, and Species Monodon monoceros. Narwhals are mainly white, while on the back there are white, green and brown speckles all over the back. These speckles are for counter shading so it is camouflaged from a topside and bottom side view.
The great white shark is a very interesting animal. They get their names from their appearance. The great white shark is very big and has a blue stomach. The great white shark can be found in the pacific, Atlantic and Indian oceans. The number of great white sharks in the United States and in the world is unknown because it is too hard to keep track of all of them. They live in salt water and do not claim territories.
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).
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
The theme of whiteness in the traditional sense usually represents purity, peace, innocence, and goodness. The theme of darkness, on the other hand, represents fear, chaos, injustice, and evil. Herman Melville in one of his novels, Moby-Dick or The Whale, challenges this idea and uses his novel in order to present the themes of duality, lack of knowledge, and fear of the unknown. Chapter forty-two of Moby Dick, Whiteness of the Whale, does not further the plot of the novel. Instead, it talks the one theme (whiteness of the whale) that the entire novel is based on and without this chapter the book loses its meaning as Melville writes, “It was the whiteness of the whale that above all things appalled me.
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).
They rarely ever dive to great depths and mostly stay near the water’s surface.
