   Description

   The length of this sea slug is up to 45 mm. It is a pale pink-blue, mottled species, with loosely spaced cerata. This species contains zooxanthellae.

   Ecology

   The habitat of Phyllodesmium hyalinum is among shallow coral reefs with Xenia octocorals. It feeds on Xenia, Xenia umbellata and Heteroxenia fuscescens. This species is more frequently recorded as an incidental to research carried out on its prey species, the alcyonarians Xenia and Heteroxenia. It is camouflaged by the similarity of its cerata to the tentacles of these corals and hides in burrows made in the fleshy base of the Xenia.
