The giant salamander (Andrias davidianus) doesn't just eat its prey ... it sucks it whole down its mouth in amazing speed:
A new study shows the animal, which can reach 50 kilograms and 1.6 meters, has an outsized talent: It's a supersucker. Researchers found that the mammoth creature, which lives in rivers in China, can vacuum up a whole fish in 0.05 seconds, engulfing the tidbit and more than a liter of water in its gaping maw ... So powerful is its suck that prey enters its mouth at accelerations comparable to those of rocket-powered cars.
