A century ago, California's state flag — emblazoned with the image of a California grizzly — was officially adopted. The bear depicted on the flag (the design is modeled after an 1846 battle flag) is "Monarch," a captive animal who'd died of old age in 1911 after he'd become a symbol of "strength and rejuvenation" for Californians after he survived the devastating 1906 earthquake. Ironically, the last remaining California grizzly was killed in 1922, so when the bear was officially adopted as the state animal in 1953, the animal was already extinct in the golden state.

Monarch, whose taxidermied body is on display at San Francisco's California Academy of Sciences, underscores the sad fact that being an icon isn't enough to save an animal from extinction. In a more recent example of this effect, this year's celebrity-studded tiger summit in St. Petersburg helped publicize the fact that there are only 3,200 tigers left in the wild — a number that doesn't seem possible considering that the animal is a mascot for everything from sports teams to breakfast cereals.
