The Unique Habits Of Migration, Feeding, And Behavior Of Other Populations

Orca whales have been in difficult circumstances ever since the first orca was captured in 1961. The first orca captured lived two days in captivity then died and the reported cause of dead was pneumonia. Many things come to mind when people think an orca is in captivity. Many people tend to believe they are being treated, they will enjoy life more, and they will live longer due to the fact they are receiving food and care. These statements are told to spectators at seaworld, marineland and many other water parks around the globe. The facts disagree with these statements. Orca are very friendly animals, there have been no recorded attacks of orcas hurting any human being in the wild. Most of them will come up to fishers boats and be

There is no doubt that humans have always been intrigued with the majestic beauty of the large giants found in all of the world’s oceans. Whales and people have had a long history together, marked by many turns of events.

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

Furthermore, the marine mammal science community, which has long maintained a neutral stance on the question of whether orcas are a suitable species for captive display, has finally recognized the need to engage. An informal panel discussion on captive orcas is scheduled at the 20th Biennial Conference on the Biology of Marine Mammals in December, the first time this topic will be openly addressed by the world's largest marine mammal science

The panda of the sea is in danger. The local Southern Resident Killer Whale J,K, and L pods population is disintegrating quickly. This is due to habitat destruction, reproductive issues, and a limited food supply. All of these factors are causing the Southern Resident Killer Whale population in the Pacific Northwest to decrease drastically and now they are a species that is listed under the Endangered Species Act. According to whale researcher Ken Balcomb, “The SRKW population was declared Endangered under the US Endangered Species Act in 2005, and earlier this year it was listed as a “species in the spotlight” by NOAA for its lack of recovery since then”(Balcomb). With recent deaths of J28 and her calf J54, many whale activist have been pushing

Historical levels of the Southern Resident Orca population are currently estimated to have been as high as 200 (Fisheries.noaa.gov, 2015). The population as of 31st December 2015 was calculated at just 84 individuals (Center for Whale Research, 2015). There is limited data on the population before the mid 70’s so it is unknown what the population pattern looked like prior to this. Appendix A shows a graph documenting the population data found by a census started in 1974, as well as modelled data from 1960 to 1974. The graph starts with a low population, possibly explained by the frequent capture of live animals for marine parks (National Oceanic and Atmospheric Administration, 2014, p. 3). After this period the graph shows fluctuations in the population, then a steady growth resulting in a peak in 1995, then a sharp decline – almost 20% until 2001. This fast decline is what prompted governments to first list the population a threatened (United States Environmental Agency, 2014). The population has remained stable in the following years but now has an endangered status (Fisheries.noaa.gov, 2015).

The conditions that the captured killer whales are forced to live in are not acceptable replacements for the wildlife habitats that they have been ripped from. All the enclosures that the orcas are kept in do not provide an adequate amount of space that the animal requires. The size of an orca in relation to the size of the tanks they are forced to live in is comparable to the

Some people argue that keeping orcas in captivity is not a problem, yet they do not realize some of the limitations and dangers orcas suffer when kept in captivity. One reason is that these unpredictable, thirty-foot long creatures are usually kept in a tank that is too small for them, compared to the ocean where they can swim freely. In captivity, space is limited. According to one expert, “orcas can swim up to 100 miles per day- a phenomenal amount, in comparison to the exercise they receive in captivity” (Cronin). While in captivity, an orca has to keep swimming in circles or float, unable to exercise adequately in a confined space. The small tanks also prevent orcas from living in their natural group sizes, or pods. “In the wild, killer whales typically travel in pods of between five and 30” (Melissa). In captivity, fewer than five whales are kept together, an imbalance that makes the whales more aggressive towards one another. This can lead to dangerous, territorial situations in which captive

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

Recent evidence suggests that whales may not have always inhabited the oceans. Bones of an ancient ancestor of modern day whales, the Basilosaurus, were discovered in Pakistan that suggest whales evolved from a wolf-like creature. This genus of an early whale lived 34-40 million years ago in the late Eocene. These fossils show many different features in common with both modern day whales and modern day land mammals. Since the discovery of these bones, many other evidences show that whales are a likely descendant of the Basilosaurus through many different ways, such as embryologic comparison and DNA testing. Whales aren’t the only suspected descendants

It’s a average, nice summer day and you and your family decide to see killer whales at SeaWorld. Once you arrive to the place and see the large animals in the tank you’re fascinated by their large size. Killer whales, or orca whales, are large marine mammals that can be found in every ocean around the world. They can swim for hundred of miles and “routinely dive up to 300 ft” (“Should Orca Whales Be Kept in Captivity”). They also live in large family groups known as pods that they will rarely ever leave. Seeing these large animals in the tanks that they make seem small due to their large size and with other whales along with marks, mainly bite marks and flopped over dorsal fin for the males, make it questionable if they even should be here and if these other whales are family in the seemingly makeshift pod. Orcas should not be in captivity because of health problems, lack of space in the tanks, and most of them are taken from their homes in the wild where their true family is.

People say that keeping orca’s in captivities is not a problem, yet they do not realize that, orcas are also human beings. There are several reasons, why keeping these thirty-feet long creatures, in captivities is a problem. One of them, which are the tank, which is too small, compared to ocean where they can swim freely. One the other side, in captivities, the space is limited. Comparatively, to how they swim out in the wild “orcas can swim up to 100 miles per day- a phenomenal amount, in comparison to the exercise they receive in captivity”(Cronin). While being in captivity, orca has to keep swimming in circles or floats. Out “In the wild, killer whales typically travel in pods of between five and 30”(Melissa). In captivities there are only few whales, so it makes them more aggressive toward one another. This sometimes can be lead to danger by killing each other for fighting to gain power of the tank.

They are not able to swim all around the world and be able to do what they do best which is to live wild and free. They are stuck in a small space with thousands of people watching them every day. Most Orcas are taking from their mothers at an early age. Although Orcas are known to stay with their mothers until about two years of age, they are taking too early so they don’t receive all the nutrition that they need to help them develop fully. If a young one is taking away from its mother to early it is more likely to die. Orcas usually reproduce once every three years. Although it is known that it is possible for them to have twins, they are more likely to just have one at time. They usually only have one at a time because they are too big. After the calf is born the mother then trains the Orca how survive. She teaches them how to find food and how to protect themselves from other animals that may be harmful to

Despite its abundance, in quantity the blue whale is now considered to be an endangered species. Blue Whales have been hunted for centuries, they can also be found in most oceans and because of this they make an easy target for hunters. A unique feature of the Blue Whale is that they are the largest mammal in existence they can grow up to 30 meters long and weigh up to 190 tons. Due to its size they are the hunter’s ultimate prize hence why they are endangered. Despite its size, its diet consists of some of the smallest marine life such as, krill, shrimp and so on.

Whaling is defined as hunting and killing of whales by humans for resources, mainly meat, blubber and baleen (whalebone) obtained from whales. These resources are then sold for commercial purposes and thus, whaling has become economical important for centuries (Joanne 2007; The Columbia Electronic Encyclopedia 2007). Scientific whaling is conducted by hunting whales for research purposes and further analysis to study on whale’s behaviour, characteristics and distribution (Joanne 2007). Commercial whaling is a controversial whaling practice that exploits whale products for trade and profit. Recently, Japan, Norway and Iceland are the major contributors of commercial whaling and deeply support any other whaling activities (Joanne 2007). Moratorium on commercial whaling 1986 is a global ban of hunting whales for commercial purposes, implemented by International Whaling Commission (IWC). Under Article VIII, unlimited scientific research is permitted but sufficient data and analysis are required by Science Committee set up by IWC (Papastavrou 2006).
