Below the tangle of vines and branches of the East Malaysian rainforest, a small contingent of ants scuttles frenetically along the shaded leaf litter. But these are no mere picnic pests -- these are Myrmoteras trap-jaw ants, fearsome predators armed with long, spiky, widely-agape mandibles -- and they are on the hunt. Suddenly, an insect-like springtail comes into the view of a trap-jaw's compound eye. With a quick rush from the ant, it's all over, and the springtail is pitifully pinned in the ant's prickly jaws.
