From entomologist, blogger and insect photographer Alex Wild comes this remarkable image of a trapjaw ant, torn asunder to reveal the wriggling, 8-inch parasitic worm living inside. (The ant, by comparison, measures about half an inch long.)
Everyone, these are trap-jaw ants. The two featured here are fighting. Watch them closely – even in slow motion, the the spring-loaded snap of a trap-jaw's maw is powerful enough to send both ants twirling in opposite directions in the blink of an eye.
