The bright orange, white-tipped structures along the Flameback’s dorsal surface are called cerata and increase the surface area of the skin. This nudibranch absorbs oxygen through its skin, so increased surface area aids in respiration. The cerata also increase the number of defense cells that the Flameback can store from its prey.
