Ask any US wildlife official how the invasive Asian carp have managed to stick around US rivers for four decades, and they'll all say different versions of the same three things. And third, the US doesn't possess any native species of fish large enough to prey on adult Asian carp, so they have very few predators. But a closer look at the four Asian carp species currently plaguing America's waters points to one glaring fact: we clearly don't know much about these fish. Fortunately, researchers have finally started getting a handle on the animal best known for its ability to jump out of water when startled, says Duane Chapman, a biologist and leader of the Asian carp research team at the US Geological Survey (USGS).
