Appearance
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. 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.Rudman, W.B., 1998 [In] Sea Slug Forum.
