Sea hares don’t look like they can put up much of a fight, but these bunny-eared slug cousins can really knock you senseless. When disturbed, sea hares (genus Aplysia) release a dark purple cloud that’s made up of ink and a sticky, milky mix of chemicals called opaline.
Today in The Journal of Experimental Biology, researchers show that the opaline in the ink cloud not only frightens and distract predators, but also interferes with their sensory organs and blocks their chemical receptors.
