Sea anemones sting prey faster than a blink

Sea anemones, those flower-like creatures of the ocean, paralyze prey with lightning speed using specialized stinging cells called nematocysts. These cells, found in their tentacles, launch harpoon-like structures that discharge venom in less than a millisecond upon contact. This rapid response is crucial for anemones, which are sessile predators unable to chase food, allowing them to secure meals efficiently. Researchers have even measured discharge speeds up to 40 meters per second. This incredible mechanism also provides defense, though some species like clownfish have evolved immunity, forming unique partnerships.
