Nearly two-thirds of the whale deaths during that time occurred during the first five years of the animal’s captivity, the team reports in Marine Mammal Science.
Although captive whale survival has risen over the years, these animals still lag their wild counterparts considerably.
The study itself appears to be an attempt to amass data supporting the practice of capturing and torturing orcas. John Jett was one of the biologists interviewed in Blackfish, the film exposing the horrible conditions Orcas live in at SeaWorld. March 31, 2011 by Jana A · 10 Comments So remember last February when the Killer Whale, Tilikum, at Sea World killed the trainer who was alongside the water?
Jason and I were discussing this last night because it was news that the Killer Whale was back and performing again as of yesterday. And then you voluntarily get into a tank (or even near a tank) with a whale that has already killed 2 other people?
Why would one who knew about the previous killings get in a tank or even NEAR a tank, with a KNOWN KILLER killer whale, a WILD animal?
We take these animals out of their native environments, put them in a tank, try to teach them tricks and expect them to domesticate and forget all of their God-given instincts. So if we want to enjoy them as entertainment, though I have personally never been to a SeaWorld show or a live whale show of any sort, we need to enjoy them as that. And if you’re going to be an animal trainer to a killer whale or a tiger, bear, rhino, whatever, just know you are taking your life into your own hands. Orcas are called Killer Whales because they kill other whales and are the true apex predator in the ocean. We have a pet that we treat like one of our own children, Buddy the Golden Retriever, not Buddy the killer golden retriever.

These beautiful creatures pass us during their migration as they travel between the warmer northern waters and the cooler seas surrounding Antarctica. The Southern Ocean Whale Sanctuary, adopted by the International Whaling Commission in 1994, provides long-term protection to the feeding grounds of almost three quarters of the world's remaining whales. Many whale species can be found off of the Rainbow Coast including the Humpback and Southern Right Whales most prominently.
If you are coming to Albany to watch the Whales, we recommend booking your whale watching tour in advance. The whales come and go in these sheltered water and it is unusual to go out and NOT see these humble, giant creatures.
Dolphins and Seals can be seen in the sheltered waters, the seals most often laze in on the warm rocks off of Seal Island. Southern Right Whales head for the bays during early winter and spring when they arrive to give birth before returning to the Antarctic waters to feed for the summer months. If you are interested in Whale Watching, you can find a Map to the Albany Pier [click here] where you will find the two whale-tour operators. So, I spun a tale of 'Whale Research Boats' filled with people who are actively caring for the whales.
It turns out this is exactly the same tale Japan, Iceland and Norway have been feeding to the public (yes, the adults!) for years. We find it not very appealing to discuss, except to point out its brief history and to oppose those still 'hunting' whales in the open ocean in outher countries.
The Southern Ocean Whale Sanctuary was established by the IWC in 1994 with 5 countries supporting the agreement and Japan opposing it.
As sanctuaries only apply to commercial whaling, Japan has continued to hunt whales inside the Southern Ocean Whale Sanctuary because its whaling is done in accordance with a provision in the IWC charter permitting whaling for the purposes of . Whaling in Western Australia was one of the first viable industries established in the Swan River Colony following the arrival of British settlers in 1829.
There are two main species of whales (order Cetacea) which form aggregations along the Western Australian coastline: the Southern Right Whale (Eubalaena australis), and the Humpback Whale (Megaptera novaeangliae). Both species migrated along the north-south coastline stopping in bays such as Geographe Bay (east of Cape Naturaliste) and Flinders Bay (east of Cape Leeuwin) for mating and breeding.
The Rainbow Coast is a national biosphere area and deserves our care and respect, please reduce your environmental impact when visiting the coast. A type B killer whale hunting for seals in the Antarctic pack ice: note the yellow tinge of algal growth that has accumulated on the outer skin. In a little over a month, Antarctic killer whales trek from their chilly residence to the warm waters off the coast of South America and back, researchers have found. This fast-paced migration seems to be an adaptation to the cold waters of the Antarctic, which have ample food for the whales but can quickly strip the heat from their skin and stop the whales from regenerating and shedding their outer layers. Due to the cold conditions of Antarctica, the researchers had a limited field season in which they can tag the whales. Map showing the full round-trip migration of a type B killer whale between Antarctica and the sub-tropics; over 5,000 miles, taking just 42 days to complete. Each of the tagged whales, if given enough tracking time, eventually made their way north into the Atlantic Ocean.

Photo of same whale photographed around the Antarctic Peninsula when it is in "yellow" state with heavy diatom coverage and also in a "clean" state. Other marine Antarctic animals are either large enough to keep warm in the frigid Antarctic waters (like blue whales) or can move into warmer waters (like beluga whales, which swim into estuaries to shed their skins).
Lots of other marine Antarctic animals make a tropical trek, but their main intentions seem to be either feeding or giving birth to their young.
Jennifer Welsh graduated from the University of California, Santa Cruz's Science Communication graduate program after working at a start up biotech company for three years after getting her Bachelor of Science in Biological Sciences from the University of Notre Dame. Killer whales have been revealed to be one of only three species whose females are known to undergo menopausea€”living on long after their reproductive years in order to help their offspring, particularly their sons, survive the rigors of young adulthood and later to help raise their grandchildren. Like human mothers, female killer whales can bear offspring well into their 30s, but then may live on for another 50 years or so to look after their families, pass on their knowledge and skills to the younger generation, and assume a leadership role in the community. Males are particularly vulnerable when young; one study suggests there is a 14-fold increase in mortality in the first year after the death of their mother. You mention that only three mammals undergo menopausea€”humans, killer whales, and pilot whales. Croft: Biologically speaking, menopause is a bizarre concept, and very few species have a prolonged period of their life span where they no longer reproduce. Do the whales, like humans, appear to undergo any other physiological symptoms or changes, such as hot flashes, as they go through menopause, or is that impossible to know? Croft: Unfortunately, we don't have the physiological data on the whales to know what changes females experience as they go through menopause.
Franks: We know that older females increase the chances of their offspring's survival, but exactly how they do this is a topic of our current research.
If there are clear evolutionary advantages to menopause, why haven't other creatures developed this?
Croft: For menopause to evolve, the benefits of stopping reproduction in late life have to outweigh the costs. Given the perceived rarity of menopause across the animal kingdom, what would whales and humans have in common?
Croft: Theory suggests that the key to understanding why menopause has evolved in whales and humans is in understanding their social structure. The authors note that 62 to 81 percent of wild female killer whales live at least 15 years. Captive-born whales faced a higher risk of dying between two to six and 11 to 12 years old. Kids who were present were traumatized, parents lost their daughter, colleagues lost their friend and SeaWorld lost its main performer when they had to take Tilikum out of the show. They are majestic creatures and always appear to be smiling, so who wouldn’t love them?
Why, though it’s horribly tragic, would anyone be surprised that a KILLER whale would be capable of KILLING another human after his history? But as the deadly, wild creatures they are and knowing that even by just going to a show it could be potentially dangerous.
What amazes me is that people forget that this is an apex predator, as are Dolphins and mammals are the only animals on the planet who kill for sport. There is an inherent risk one takes in working with animals and those that do it know the risks, and accept them.
The Great Southern Ocean is home to a huge whale population who breed and feed in the bays.
The King George Sound is a sheltered harbour offering two passages to the Great Southern Ocean.
The story covers up the fact that these countries are STILL slaughtering whales, dolphins and porpoises.
The status of the Southern Ocean Sanctuary is reviewed and open to change by the IWC every 10 years.
Japan also lodged a formal objection to the sanctuary with regard to minke whales, meaning that under IWC rules, the terms of the sanctuary do not apply to Japan with respect to minkes. The industry had numerous ups and downs until the last whaling station closed in Albany in 1978.
Other species occasionally caught were Sperm Whales and Blue Whales, although these tended to be seen mainly along the southern coast of Western Australia. Their white areas are often stained yellow from an algal species that grows on their skin in the Antarctic's frigid waters.
About half lost their tags in the first three weeks, but the remainder traveled north to the Atlantic Ocean off South America. They traveled just far enough to reach the tropical waters off South America, where they slowed their pace slightly, still heading north. Durban suggests that these whales may travel north to warmer waters in groups to slough off their yellow skins without freezing, returning to the Antarctic waters a pristine white, only to pick up more algae and turn yellow again. Perhaps these other marine animals use this time to shed their skin, so they don't make a separate trip, Durban said. She has worked at WiredScience, The Scientist and Discover Magazine before joining the Live Science team. It is a rare evolutionary trait, shared with humans and pilot whales, that may have much to do with the killer whales' success as a species, say British researchers at the University of Exeter and the University of York, who have conducted a 30-year study. Their steadying presence is believed to dramatically improve a young male offspring's survival chances.

Looking at this we can see that female killer whales stop reproducing in their 30s or 40s, yet live into their 90s. Anecdotally, there are some suggestions that other species of whales may undergo menopause as well, particularly sperm whales.
Given the size of the animals and the fact that they live in the open ocean, it is difficult to get such data.
Our team has a few ideas about what could be going on here, and we can speculate that they may provide support during encounters with other whales and help with foraging through knowledge and leadership. Theory suggests that the key to understanding why menopause has evolved in the killer whales is in understanding their social structure and how a female's relatedness to her group changes as she ages.
In both humans and whales, as females age, their relatedness to their local group increases. According to the report, killer whales typically live almost three times longer in captivity in the U.S. One-third of the animals had been born in captivity, and the rest had been caught in the wild.
In contrast, only 27 percent of the now-dead females in the captive study survived that long.
So managers could try to avoid separating whales from their mothers or transferring the animals to other parks during those times. In contrast, only 27 percent of the now-dead females in the captive study survived that long.) is a bit misleading. A wild animal that happens to know how to follow a few directions and do some fancy-dancy tricks. Animal rights aside, entertainment potential aside, removing the essence of the creatures is impossible. The means they use to train these animals just uses their natural instincts to perform a series of behaviours, the same way we use our dog (also a predator but one domesticated 10k years ago) to train him to do what we want. Zoology is my major and reptiles are my focus, and I understand the risks that come with working with those animals. During the 2004 meeting a proposal was made by Japan to remove the sanctuary, but it failed to reach the 75% majority required (it received 25 votes in favour and 30 votes against with two abstentions).
The catch of the 2005 season (Dec 05-Mar 06) inside the sanctuary included 856 minke whales and ten of the endangered Fin whale. Website photographs are copyright protected and are editorial in nature and are not for sale and may NOT be used without written permission.
More data is needed, however, to establish whether these other species actually do undergo menopause. It is certainly possible that other species may also have menopause, particularly in species that live in close-knit family groups, but this is not yet known. Killer whales live in close-knit family groups where both sons and daughters stay with their mother her entire life. This increase in relatedness means that evolution will favor females that switch from having their own offspring in late life to helping their offspring and grand-offspring survive and reproduce. You take a wild animal that kills other whales and coop them up and expect them not to become angry and discombobulated. There is an inherent risk in working with predators and a high public demand to see these animals, and that leaves us at a crossroads. We do it for the love of them, to help others understand these animals and to bring awareness and knowledge to those who might otherwise never have a chance to see these animals in the wild.
During that period, several groups of whales left for their warm-water destination at different times. Round trip their vacation covered more than 5,000 ocean-faring miles (9,000 kilometers) in about 40 days. Under these conditions, as females age, their relatedness to the group increases and there comes a point where females can benefit more from switching from having offspring themselves to helping to care for either their existing offspring or grand-offspring. The same as astronauts know they might not come back from a mission, we know that our lives are at risk.

I’m not a whale expert, just a meager little blogger giving my opinion based on what little I know and hear. A petting zoo is just a place to ask for getting your finger bitten off by a llama or ostrich. They can’t truly understand our communication or body language and react in their own way.
