Melibe produces a sweet fruity aroma when handled and this gives the group name " bouquet".
This chemical odor is used to attract others in the hunt for a mate. Many sea slugs produce chemical defenses which make up for the lack of a protective shell, spines or other defenses perhaps this works for the Hooded sea slug. "Predators may include fish, kelp dwelling crabs and sea stars, but when disturbed Melibe leonina has the ability to autotomize (shed) its cerata. This will hopefully lead the would-be attacker away as the discarded appendages float off, or at least cause a distraction long enough for the sea slug to make an escape."
The images/video below were taken a Seahurst Park in Burien WA on 8-2-15.
