Phyllodesmium koehleri is characterised by its club-shaped cerata, relatively thin at the base but expanding to a much greater diameter near the tip. Each ceras has many large pointed tubercles radiating out laterally. Each tubercle has a brownish duct of the digestive gland running out to the tip.
The body, including oral tentacles, rhinophores, foot and cerata, is translucent with some white dusting, thin brown streaks and patches are scattered all over
Phyllodesmium koehleri seems to feed on softcorals, members of the Nephtheidae, probably Paralemnalia or Lemnalia. Here it is on its possible prey.
Like other members of the genus Phyllodesmium it is what Bill Rudman calls "Solar-powered Sea Slugs".
