This unusual aeolid nudibranch appears to be a member of the Phyllodesmium genus, though I am unable to find another published photograph that matches both the coloration and shape. Most aeolids are capable of shedding cerata if attacked, leaving the predator with only a piece while the aeolid escapes relatively unharmed. Some aeolids are also known to store stinging cells called nematocysts from their meals in the tips of their cerata, where they remain unfired until an unsuspecting predator attacks. Identification: undescribed; therefore Phyllodesmium sp. Click here to go back to the thumbnail page
