Phyllodesmium hyalinum can be distinguished from Phyllodesmium crypticum with its rounded anterior foot corners
rather than tentacular, having the anal papilla located above and posterior to the second arch of cerata
on the right rather than within the actual arch, and the pigment of the dorsal body wall obscuring the ducts of the digestive gland.
Both possess nodules on their cerata however those of Phyllodesmium hyalinum are slighter in appearance.
