Could you imagine being torn apart from your family and stuck in a concrete cage for the rest of your life? Research has shown that orca whales are among the most intelligent creatures on this earth. Many believe orcas to be part of the whale family, however orcas are actually part of the dolphin family. This species differs from any other whale species, as they have large, complex brains, and navigate by using a melon (a structure in their foreheads) to create clicking sounds, otherwise known as sonar. It is believed that these creatures are also among the most social animals, as they travel in large groups of families called pods. Pods can travel hundreds of miles per day, and sometimes dive as deep as 866 ft. Killer whales can be found …show more content…
The first Orca was captured in 1961 in Newport Harbor, California, this whale was a mature female, who had been found disoriented and sickly. Two days after her capture she had smashed her rostrum into the walls of her tank and died instantly .A few years later, the second attempt to capture an orca whale came in 1964, near East point, Saturna Island in British Columbia, the whale, named Moby Doll, lived in captivity for about 87 days, until he died from a skin disease due to the harbor’s low salinity water (The First Captive Killer). In addition to the first few captures, many of the initial attempts to apprehend killer whales and hold them in captivity were found to be unsuccessful. In conclusion, unless it is shown to be beneficial, orca whales should not be held in captivity. The act of holding orca whales in captivity is detrimental to the physical health, their social health, and also endangers the life of the humans working with these …show more content…
Orca whales travel in large groups of families called pods. Pods are a group of whales, all related. In the process of capturing the whales, the young whales are torn away from their families, which is later slaughtered, and towed to a park where they are put into tanks with other young whales from different pods and even different parts of the world. These whales do not get along, which results in fits and stressed, anxious
These killer whales are massive creatures living in these cramped pools not doing what they want to do when they want to do it. Mr. Jett and Mr. Ventre also said “...Typically spending their entire lives within tight family groupings, orcas captured from the wild, have been traumatically extracted from the security, comfort and mentoring which these groupings provide. Captured animals are confined to small, acoustically-dead, concrete enclosures where they must live in extremely close proximity to other whales with which they often share no ancestral, cultural or communication similarities.” Seaworld ends up throwing these animals in random groups of whales that are not their families, having whales that have never been outside of the concrete wall, to whales that all they know is the wild. The Documentary Blackfish states that one of the killer whale
Second reason why they shouldn’t be kept in a captivity. You can’t recreate on orcas natural environment. The pods sea world cannot hold 40 or more whales which are usually in a pod. If it holds 40 orcas they will make more babies and after their gonna be so much whales and the water won’t hold that much whales. Because whales are the size of bus school and is just like 40 bus
Out of the 156 whales they have taken into captivity from the wild, 129 are dead. Including orcas bred within SeaWorld, at least 165 have died in their facilities (Schelling). Another falsehood SeaWorld claims is that collapsed dorsal fins are completely normal and common of all male orcas. It is actually quite rare to find in the wild, while every single one of their male whales has a collapsed dorsal fin (“8 Shocking Facts…”). SeaWorld also guarantees that they never separate a calf from its mother and even have posted a picture of a baby and its mother as proof. What they didn’t tell the public was that soon after that picture was posted they shipped the calf off to Spain alone to a different park. A past trainer even said that there had been at least 19 separations of mother and calf that he knew of at his location. All of these factors previously stated added up have a large influence on the whales mentally. Many whales are afflicted by psychosis and anxiety and in turn are given drugs such as Valium to keep them performing in shows. There have been various occasions, often swept under the rug by SeaWorld and away from the public eye, where the drugs didn’t work enough (Schelling). There
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.

The whales are usually pregnant for 15 to 17 months; but having young every 2 to 6 years. In captivity about 163 orcas have died. As well as about 30 miscarried or stillborn calves (“10 Things…”). SeaWorld force breeds the orca’s. They do this by having the animal lye on its back while they masturbate it. The people take the sample and put it inside of a female (“The Fate of…”). They do this to make the numbers of orca’s they are capturing to go down. In all actuality they are making things worse. They have inbred these animals. They don’t know what it could do to the baby inside of the mother. It could come out with some type of deformation, and the wiring in their brains could become
Suppose you were kidnapped from your family as a child by an alien species while your family watched in despair, crying out helplessly for your kidnappers to not rip you away from them. Now imagine then being strapped down and transported to a place unknown and once you arrive, you see that some of the other children that were also kidnapped have died. You then witness something that will forever remain engraved into your mind; you witness those monsters that took you hostage cut the children open, fill their bodies up with rocks, tie an anchor onto their feet and throw them into the ocean. The monsters then throw you into a tiny cage; you learn that you will not only never see your family again and die in that confinement but you will also work for these monsters and perform as a source of entertainment for them. You spend every night locked away into an even smaller steel cage that gives no freedom of movement at all and aren’t fed if you displease your new masters. Although this sounds like an outline for a horror movie, it is not. It is happening in real life and in our world. It is horrific, not only unethical but inhumane. This depicts the capturing process and life in captivity for public display of Orcinus Orcas, popularly known as Killer Whales since 1961. Although some laws regarding the capturing of whales have changed, whales are still being treated unethically. Just as inhumane as it is for this to be done to humans, it is equally inhumane for it to be done to animals. According to the Merriam-Webster dictionary, inhumanity is “the quality or stage of being cruel to other people or to animals” (dictionary.com) and that is what their captivity is...
They succeed in catching Tilikum, a large male orca, along with two other females, and almost immediately, an important question is raised in the viewer’s mind: What gives humanity the right to incarcerate and separate these animals from their natural environment and their families? As the documentary progresses, Tilikum begins to exhibit frustration and aggressive behavior at the amusement park due to the fact that he is being kept in a small underwater storage container when not on display. Eventually, this treatment leads Tilikum to kill his trainer by dragging her to the bottom of the performance tank and forcing her to drown. At this point, another question is presented: Is Tilikum’s aggressive behavior a product of nature, and the nature of orcas as a species, or is it due to his coerced captivity? Over the course of the documentary, a number of killer whales are caught and brought to different aquatic parks where the viewer gets a behind-the-scenes look at what happens to these animals and their families upon imprisonment.
Underwater shark nets make us feel safer at the beach,but are we? That’s the question. Are we safe? There are lots of possibilities that the shark, with sharp like knife teeth, may outsmart us. Because of shark attacks we use nets, called shark nets. However, that doesn’t mean nets used in the past prevented shark attacks. These nets don’t only trap sharks they trap other sea creatures.
And even a six year old wasn’t blind to that fact. The issue of keeping Orcas in captivity and under the care of man has been a controversial practice ever since the first dolphins and whales were taken into aquariums for the amusement of humans. In more recent times, the documentary Blackfish (which has been recently broadcast on popular TV stations such as CNN) that focuses on Tilikum, an orca held by SeaWorld, has brought to light the controversy over captive killer whales. Orcas are majestic, beautiful, and intelligent creatures that should not be kept in captivity for our entertainment because of the harm they cause. SeaWorld, a leader in the captivity and use of killer whales for entertainment, has counterattacked the points made by the documentary Blackfish, which brought many points to light.
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.
In recent years, humans have gained the ability to tame and train these creatures. Killer whales should not be kept in captivity simply because it is cruel, unnatural, and dangerous. Orcas, or killer whales are majestic giants of the sea. They are actually
You’re sailing in a whale watching boat in the big blue open water of the Northern Pacific Ocean. You spot a lonely seal on an iceberg and then suddenly a fast wave approaches it. The seal slips off the iceberg and falls into the mouths of two generations of hungry Orcas. Killer Whales which are widely distributed in the world’s ocean, but the status of most populations of killer whales is unknown (Killer Whale (Orcinus orca)). But soon the killer whale will become rare and vanish if we don’t do something remarkably fast.
Hundreds of people, who get in the ocean every year, are almost none that encounter sharks. Even if you're lucky enough to see a shark big enough to bite you, you're much likely to die from a heart attack than getting bit by one. Shark attacks are mistakes and the idea of a shark off every beach waiting for people to come in the water is completely untrue. I will inform you on the background knowledge of sharks and the reasons why humans should not be afraid only aware.
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 problem I have chosen is the problem of endangered species. An endangered species is a group of organisms that have a risk of becoming extinct. More than 90% of all species that have ever lived on earth has become extinct. Many reasons for this are habitat loss, predators, too few organisms for sustainable reproduction. Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the coast and in the ocean. Rising sea levels can
