Killer whales

In their paper “Trans-Pacific Consumption of Cephalopods by North Pacific Killer Whales (Orcinus orca), “ Hanson and Walker points out that cephalopods, specifically squid, may be a larger part of the diet of many transient killer whales in the North Pacific Ocean that was once thought. They identified three particular ecotypes of whales observed in the North Pacific which include residents and offshores that both feed primarily on other smaller fish, and transients which feed on marine mammals. The research involved acquiring four female killer whale specimens from four different locations. Two of these killers were West coast U.S. transients, one was an Eastern Tropical Pacific pelagic from Hawaii, and the last was a Western North Pacific…

New Zealand Killer Whales and Penguins What exactly are cetaceans? The Cetaceans family includes whales, dolphins, and porpoises. Even though the cetacean family depends on water or more specifically the ocean for survival, they are mammals just like we are. Warm blooded, give birth, nurse their young, and breathe air through their lungs doesn 't that seem familiar? Yes they have the same characteristics as us which makes us both mammals. Scientist believed that about millions of years…

The killer whale or orca is another name for species Orcinus orca. It is a toothed whale that belongs to the family Delphinidae in the order Cetacea.. They are found globally in all oceans. In fact, after man they are the most widespread mammal in the world. Killer whales live in pods. The structure of the pods are usually matrilineal. This means that the offspring wait with their mother throughout life.The individuals in a matrilineal group travel closely together. The killer whale worldwide…

“If you were in a bathtub for 25 years, don't you think you'd get a little psychotic?” Lack of space and communication affects the lifespan of a whale. Knowing that, dont you want to know why at least 150 orcas have died in captivity. Even though I feel this way everyone has their own opinion on the issue. For example, some people can like the idea because they feel like it’s a way to rescue whales. It just depends on your personal opinion. Killer Whales should NOT be kept in captivity because…

Killer Whales, their name alone makes a bold statement, and it is no surprise that people flock to areas that showcase these majestic animals. Spectators watch in awe as these animals put on a show with their trainers. Venues, such as Sea World, take claim to the idea that these shows support education, research and conservation of killer whales12. Alternatively, many state that the use of killer whales for our entertainment is not only dangerous to people, but that it violates the five freedoms…

Killer whales are the epitome of teamwork when it comes to hunting. When confronted by a pod of killer whales the prey has very little chance of escaping. Killer whales can be found all over the earth’s oceans and nearly everything is on the menu, which makes them an important apex predator. An animal’s feeding habits such as what and how much can determine how much of an impact the animal has on the ecosystem. In the case of the killer whale it clearly has a notch at the top of the marine…

this study I want to tag Biggs killer whales (Orcinus orca), also known as mammal eating or transient killer whales, in the mid-Salish sea. Biggs killer whales are named after Michael Bigg, a Canadian marine biologist who is considered the founder of killer whale research (Paterson, 2002). Bigg was the first scientist to look at the differences between killer whales that preyed on fish and stayed in one home range all year and those that preyed on mammals and live in larger unknown ranges. It is…

the killer whale, takes place in the sea; that is where they belong. In 2010, a killer whale that belongs to SeaWorld killed a trainer at SeaWorld’s Shamu Stadium in Orlando, Florida as stated in SeaWorld Trainer Killed by Killer Whale; however there is an argument on whether the killer whale genuinely killed the trainer. The news reports claimed that the trainer named Dawn Brancheau died from the attack of the killer whale; thus this tragic event shocked the whole nation. There have been…

Shamu, one of the most famous killer whales known to mankind. This whale has become well known throughout the several years that Sea World has been around. As time progresses, there has been various studies that have justified whether or not Sea World promotes a good atmosphere for these massive killer whales and whether or not these whales should be taken out of their natural habitat in order for multiple peoples’ entertainment and pleasure. Whoever was considering taking these animals out…

Orcas, more commonly known as killer whales, should not be used for entertainment. Some other people, on the other hand, think killer whales should still be used for entertainment. Experts have established, though, if killer whales stay in captivity their health will be endangered, and their lives will be shortened. Still, some people believe killer whales should be used for entertainment. The killer whales bring in a load of money and people who work at places like SeaWorld and Dutch Wonderland…
