The jaws that jump: trap-jaw ants have smashed the record for fastest predatory strike on Earth, with mandibles that double as spring launchers

O. bauri is a member of a large group of trap-jaw ants whose bodies and trap-jaws come in a variety of sizes. That should enable Patek and Suarez to determine the evolutionary history of the jumps, as well as which body parts make for the best jumping. Fortunately, no one has any plans to allow these little beauties to gain a foothold in south Florida. Otherwise my next set of scars might go a lot farther up my leg.

Adam Summers (asummers@uci.edu) is an assistant professor of bioengineering and of ecology and evolutionary biology at the University of California, Irvine.
