Meet Mike. He’s 21 years old, 20 feet long, weighs about 10,000 pounds. He speaks a language that was taught to him by his elders: a series of squeaks, clicks and squeals that allow him to coordinate hunting strategies with his clan. His species is the apex predator in the eastern Pacific. He also babysits.
Mike is often seen protectively swimming alongside his younger siblings, part of a group of 80 orcas known as the Southern Residents that spend their summers fishing in the vicinity of Puget Sound. But over the past decade the babysitting gigs have been too few and far between. Not enough young orcas are making it through pregnancy, birth and into adolescence. Toxicity is a problem, as it is for all the world’s large marine mammals. But lack of food—Chinook salmon—is a death sentence. Acknowledging as much, NOAA put Mike and the rest of the Southern Residents on the Endangered Species list in 2005.
