Brainless Jellyfish Actively Hunt, Surprise Experts

For most, jellyfish have always been those overly alien things that float in aquariums and across our television screens during brief stints of self-education. Ah, a jellyfish! Look how it... is weird. For most, that's about as far as they can go when describing these creatures. They're not "clever," or "scary" or "wild." In fact, some are even mistaken for drifting plants, barely moving as the currents dictate where they head. However, researchers have now identified one group of jellies that actively lure and capture prey - a revelation that soundly disproves assumptions that these creatures lead a mindless existence.
