Phyllodesmium longicirrum, common name the solar-powered phyllodesmium, is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.[1]

The distribution of Phyllodesmium longicirrum includes Australia and Indonesia.[2]

Description

This is a very large species, growing to at least 140 mm. Phyllodesmium longicirrum contains photosynthetic zooxanthellae, which allow it to draw energy from sunlight, hence its common name, the solar-powered phyllodesmium.[3] This is actually a misleading name, as several other species of Phyllodesmium are also capable of photosynthesis, although this is developed to the greatest extreme in this species.[4][5]
