Despite hopes, missing killer whale likely dead

Nature sucks. If you're a killer whale, and you swim far up a river in remote Southwest Alaska, and you get confused as to where you are, you die. None of the other whales call for a search and rescue. None of the other whales come to look. You don't get saved. You die. And then you become a national celebrity, while everyone fantasizes about the one that got away. You know, the immature killer whale that somehow could have escaped to the sea to survive when two adults died. Sorry, nature doesn't work that way. Usually (television nature shows, anyone?) the young are the first to die. And if the adults die, the young are almost always doomed to die. Anyone who saw the photographs of the Nushagak River whales earlier this week could see what was coming. They were living in freshwater, and freshwater was essentially eating them alive. The skins of killer whales did not evolve to dwell for weeks in fresh water. They are a saltwater species. After weeks in freshwater, their skins looked like yours would if you bathed in battery acid. A little splashing you could survive. Full immersion? Forget it. The whales made a bad decision. They paid nature's price. Who knows why they took off up the Nushagak River. Maybe they were foolishly chasing salmon. Maybe they were just foolish. Now they are simply dead. Most Alaskans will understand. A lot of us live close to life and death. Who knows what the reaction will be Outside, where many Americans seem to think everyone and everything is supposed to live forever. It doesn't work that way. It's sad. I know. It's painfully sad. But it is the way of life, and death. Not that everyone wants to accept it. There are still those holding out hope for the missing whale the way some hold out hope for avalanche survivors days after a snowslide. Hope is a wonderful thing. It is also, at times, futile. And it has ways of morphing into less savory behaviors. SeaWorld, a company which runs marine parks (zoos if you will), is already being attacked for sending a veterinarian to Alaska to aid in necropsying (the animal version of an autopsy) the dead whales. SeaWorld's veterinarians arguably have more experience with killer whales than any veterinarians in the world, but of course there are those who see hidden agendas. "SeaWorld may hope to somehow ensnare the missing juvenile whale for their amusement parks, and/or they may also hope to gain tissues for their artificial insemination project from the dead animals,” writes Candace Calloway Whiting at SeattlePi.com. "Hopefully the young whale has managed to return to salt water and has already reunited with extended family members, but at this point no one knows about the type of orcas that went up the river, their culture, or their families." "Their culture ... their families." Oh, if only nature worked this way. The reality is that the juvenile whale in question would be lucky to be found alive by SeaWorld and sent to live among people who would care for it for the rest of its life. But it is unlikely to be that lucky because the odds are it is dead. Why? Because this is nature, and the one thing animals of all sorts do in great numbers in nature every day is die. The only difference between these whales dying and other whales dying is that humans happened to witness their deaths.

PCB contamination really needs to be addressed at a much higher level as it is possible that this is what messes with the hormones of these whales -- PCBs (and PFCs) alter reproductive organs and exert thyroid-like effects in the brain, making them do strange things, from my understanding. And likely, we will see more of these events until our commitment to cleaning up the waterways that these magnificent creatures have no choice but to dwell.

Presumably, PCB testing will figure prominently in the study of these orcas. Hard to imagine this question would not be pursued. In terms of commitment, and where we are with it: The USA banned PCBs more than 30 years ago. Many companies were put out of business. Entire industrial & economic sectors have been affected; have made an ongoing response effort. And of course, we have spent really large amounts of money, on removal & remediation for this single chemical. Our commitment is proven. We have not spared the rod. There are 'some' data suggesting that 'some' orca populations might still be showing an ongoing apex predator effect. The data are not what we would really like them to be, even in the best cases (Puget Sound & southern BC), and they are not especially clear-cut, even in the limited extent that they inform (we don't want to be systematically harassing wild orcas, for thorough sample-coverage). For most populations we have no data at all. In terms of salmon - they only live a few years. Once the PCB supplies began to be cut off, the base of the food chain 'cleared' quickly, and so do subsequent salmon generations. Not that PCBs are not entering the food chain 'anywhere', or that they have totally vanished (which may well be 2 ways of saying the same thing) but our commitment is real, and has resulted in worthwhile progress on this natural-habitat issue.

Many people in our greater culture are pretty-much doing what these whales did. They are taking a wrong turn into a make-believe stream of reality. Like with these whales up the river, a fantasy-relation with nature is not these folks' friend, cannot sustain them, and will in the end let them down cruelly. |
