“Dolphins often display a playful attitude which makes them popular in human culture” (Science World Kids.) In this paper I will talk about what dolphins eat, how they sleep, what their environment is, and other interesting facts. Species of dolphins Dolphins are a group of aquatic mammals called cetaceans. They are mammals because they are warm-blooded and they give birth to their young. The word “cetaceans” means celus in Latin and kelos in Greek both of which mean large sea animal (or creature.) There are thirty-two types of dolphins. One type is: the Bottlenose Dolphin (it’s blue-gray with a dorsal fin and a very white belly. It weights an average of 350 pounds and its length is about nine feet.) The Common Dolphin’s average length is eight feet and weight is about 165 pounds. Its upper body is either a dark blue or black and it’s under body is white. It also has golden stripes on the side of the dolphin and a dorsal fin. Another type of dolphin is the freshwater river dolphin. They have long snouts, small eyes, and they can only dive for about one minute at a time. There are thirty-two species of dolphins, but only 12 of them are freshwater river dolphins that live in South America and North and South Asia. All river dolphins have large and broad pectoral fins and a mobile neck. Dolphin Enemies Dolphins are natural enemies with sharks. The larger sharks (like the great white) normally eat smaller dolphins because they are easier to prey on. They are also natural enemies with whales. The killer whales have eight to eleven teeth on the upper jaw and eleven to thirteen on the lower jaw. They are also very good at staging assaults on other cetaceans.

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.

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.
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.
Orcas, commonly known as killer whales, are actually the largest member of the dolphin family. They were given the name “killer whale” by sailors who often observed them attacking and killing seals, sea lions, walruses, penguins, dolphins, polar bears and even other whales (Orcas).
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.
Striped dolphins, Stenella coeruleoalba, are some of the most abundant and well-known dolphins in the world. These dolphins can reach the length of about 9 ft (2.7 m). The males weigh up to 350 lbs (160 kg). The females weigh 330 lbs (150 kg). Striped dolphins have a slender body shape combined with a long beak, which is separated from their forehead, and they also have a curved dorsal fin. The beak, tapered flipper, tail, and back, or cape, are dark blue/gray. The name “Stenella coeruleoalba” refers to the pattern of blue and white stripes along the lateral and dorsal fins of their body. Their underbelly (ventral) is usually white. Their primary feature is a black stripe that runs along their full length and to their flippers. There is also a dark blue patch around the eyes. Calves and juveniles may have more muted colorations and patterns.
These two sea creatures both live in oceans,but have very different lives in the deep blue sea.Such as their brain smarts.A dolphin is the smartest sea creature in the world.For where a squid,doesn’t even have a brain.The squid also has no backbones.The dolphin does.Even though they have these different traits they do have many similarities.They both are very large creatures that can grow up to six thousand six hundred pounds!Both of them have no hair on their bodies.
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.
After watching several documentaries on how poorly killer whales are treated in captivity, it drew me into researching more information on the treatment of Killer whales that are kept in captivity. I found several scientific journals, and articles on wild life facts of killer whales and I found published books on the treatment of killer whales in captivity. The information I found includes both wild killer whales and killer whales kept in captivity. With the information I found, I plan to prove the shortened lifespan and health problems killer whales get while living in captivity are not normal. In fact the information you learned about killer whales from aquariums and commercial parks are false. This paper will argue why killer whales should not be held captive in commercial parks. This Paper will include information on the killer whale’s diet, the killer whale’s communication, and the killer whale’s physical traits.
Orcas, also known as killer whales, are amazingly intelligent and are a top predator, much like humans. However, when the top predator of the ocean collides with the top predator of land, the situation can become fatal for both humans and the whales. Holding these incredibly massive marine animals in captivity is not only inhumane and detrimental to the whale’s health, but also a potentially fatal activity for humans to participate in.
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
When Indo-Pacific Humpback Dolphins are first born, they are dark gray and get lighter as they grow older, sometimes this will cause spots (WCD). According to Whitfield on page 114, when the Indo-Pacific Humpback dolphin is young it has a normal streamlined body figure, but when it grows older it start to form fatty tissue humps. They have the average lifespan of 40 years (WCD). The Indo-Pacific dolphin can be between 6 ½ feet to 10 feet long with 120 teeth in their long beak. Using their long beak to eat, these dolphins swim up to the shallow waters and hunt for fish (Whitfield 114). Indo-Pacific dolphins are not the only type of dolphins that pray on the
At maturity males are typically close to nine meters in length with the females being slightly larger. Throughout its adult life the whale shark is mostly solitary traveling alone and staying to itself. Due to the size of it doesn’t have many predators though on occasions killer whales have been known to attack Rhincodon typus (Rowat 2012).
