Sea hares use chemical defenses against predators

Sea hare ink has an interesting effect on the sensory systems of predators

Sea hare ‘ink’ has an interesting effect on the sensory systems of predators like lobsters

Ever wonder what the purpose of that purple ‘ink’ exuded by sea hare’s is?  Well, a recent paper in the Journal of Experimental Biology shows that this purple ‘ink’ called Opaline blocks the chemosensory perception of crustacean predators such as lobsters.   Presumably, by ‘blinding’ the chemical senses of it’s predator the sea hare can make it’s escape.  Interesting and sophisticated biology for a common denizen of Abaco’s seagrass beds!

This and other defenses of the sea hare are covered in BBC Science & Environment section (BBC Coverage) and are summarized by the publisher as well (Journal Summary).
