Phyllodesmium briareum

…is a species of Favorinine nudibranchi (Facelinidae, Favorininiae) which is widely distributed throughout the Indo-Pacific and Australia. Phyllodesmium briareum are noted to feed mainly on various corals, specifically members of the suborder Sleraxonia. P. briareum is also noted for its ingenious camouflage, its cerata (the gills along its back) have been modified to look almost exactly like the tentacles of the Sleraxonian coral Briareum violaceum (which you can seen in the second picture above) this allows P. briareum to feed among B. violaceum without being targeted for predation!
