Remarks :

Looks like Placida sp. 1 in Nudibranch and Sea Slug Identification Gosliner, Valdés and Behrens, 2015
    This species is part of the Placida dendritica complex. There are probably many regional species around the world being identified as this group, so I use the name of Placida sp. 1

Bibliographic data :

In Hawai "Although seldom seen due to it's small size and superb camouflage,  Placida sp. 1 is a common species found on green algae of the genus Codium , particularly Codium edule . It occurs in moderately protected to moderately exposed locations at depths of  < 1 to 2 m. It shows a diurnal activity pattern when held in dishes. We've observed it feeding on Codium edule and, when feeding, it flattens its cerata laterally against it's host."
