Orcas are highly intelligent; they often live in groups called pods. Each pod is made up of several females and their offspring the members of the pod communicate through underwater calls. A pod may work together to hunt. Despite their name, killer whales are actually dolphins; they are the largest kind of dolphin. They have not been known to attack people in the wild. Orcas are up to 30 feet long, they weigh up to 10 tons, they have shiny black backs, and they are white underneath. Orcas feed on a wide variety of animals. They hunt salmon and other fish, seals, dolphins, and whales. Orcas are large ocean animals; they live in all the oceans, especially in cold waters Orcas live in the ocean, and they are large, fast hunters. They are mammals, animals that feed their young on mother's milk. “Years ago, sailors saw orcas kill whales. They called them ‘whale killers.’ Over time, people started calling them ‘killer whales.’” (Info Bits, Gale)

Female orcas are a little smaller. They are about 17 feet long and they weigh about 2 to 4 tons. Orcas live in all oceans, but many live in the Arctic and Antarctic regions.

    Although there have been many animal advocates protesting against SeaWorld, there are other people who don’t mind the Orcas being at SeaWorld. “Shamu the show and the marine parks’ collection of orcas have been inextricably linked to SeaWorld since the San Diego park’s origins more than a half century ago” (San Diego Union-Tribune 1). The killer whales have been the face of SeaWorld for many years. The Orcas are one of the main reasons people go to Seaworld. Shamu is the famous name that all the Orcas are known as, because of the captive killer whale that appeared at shows in SeaWorld San Diego in the 1960’s. “She was the fourth orca ever captured, and the second female, after her death, the name Shamu continued to be used in SeaWorld…

    The first story I heard that referred to orcas being held in captivity, was about a young orca named Tilikum. He was ripped from his family when he was only two years old when he was only 13 feet long. After his capture, he was kept in a cement holding tank for close to a year at a marine zoo in Iceland as he waited to be transferred to a marine park in North America. He was held captive against his will, all he could do was swim in small circle and float aimlessly at the surface of the water. Tilikum was very far away from the expansive ocean where he would swim over 100 miles a day alongside his family members. Finally, he was transferred to the rundown…

    Killer Whales Research

    With research and studies being conducted on both wild and captive Killer Whales, data and information has been generated that adds question to the health issues associated with captivity. “The killer whale (Orcinus orca) has proven to be among the most difficult of all species to hold adequately in zoological facilities. The killer whale is a particularly large-brained and long-lived species who evidences a high degree of social complexity in the wild.” (Noonan) Their behavior and relationships with other whales within the family, known as a pod, creates an immense bond between the animals. Whales that were documented inhabiting the Pacific Northwest, remain in their natal group for most, if not all, of their life. (Robeck) When in captivity,…

    The average age of death of an Orca at SeaWorld is thirteen years.“No Aquarium, no tank in the marine land, however spacious it may be, can begin to duplicate the conditions in the sea.” Jacques-yves Cousteau said in the film, “Blackfish.” Who would want to go to marine parks knowing that the animals captive there are dying more rapidly than those in the wild? In other words, SeaWorld's tanks cannot compare to the ocean, the tanks at SeaWorld are approximately three-hundred and fifty feet long. The average size of an Orca is twenty to thirty feet long, though in the wild an Orca travels more than one-hundred miles a day. A whale would have to swim one thousand two-hundred and eight laps a day in a tank that size to reach the amount of miles an average Orca swims in the wild. “Life in cramped tanks is no prize for Orcas and Dolphins, who want to be free with their families in the ocean,” Bob Barker quoted. The male Orcas in SeaWorld all have collapsed dorsal fins, which is not common in the wild. A collapsed dorsal fin is a sign of a unhealthy or injured Orca. Most of the whales are injured from the other whales that live in the tanks along with them. Living in such confined spaces creates tension among the whales which leads to attacks against each other. In the ocean, there is a vast amount of space for the whales to eventually flee. Although in the tank,…

    In the wild, they live in complex social groups called pods. Pods can range from 2 individuals to 40 members, and the pod members are usually family and are very close to one another. What marine parks do? Tear the orca families apart by stealing a member of the pod and basically putting them in jail and holding them hostage. Usually, all the other orcas in the tanks at marine parks are from different groups and they don’t even speak the same language!…

    • 3 Pages

    The cruel act of confining Orcas to bathtub sized pens is not only inhumane, but also a hazard to current and future Orcas by affecting their physical, mental, and social health. Orcas, who are more commonly known as killer whales, can grow up to twenty to thirty feet on average and swim up to 100 miles a day, keeping their body healthy and fit. Aside from their large and strong body structure, Orcas are highly intelligent and social animals that work together in pods when hunting while even being capable of swimming as deep as thirty feet. So why in captivity, are Orcas being kept in pools that range from eighteen to twenty-eight feet deep?…

    Orcas, also known as killer whales, have been in captivity for over fifty years. The magnificent stunts the animals are trained to do is jaw dropping. Killer whales, on the other hand, do not seem to feel the same positive regard. Infact, they have killed or injured more than one-hundred people during their stay in captivity. Keeping killer whales in captivity not only threatens the whales, but harms humans as well.…
