Seven specimens of this unidentified Eubranchus species were found at Enewetak Atoll and several more at Kwajalein. Many of the Kwajalein animals were found in the fall of 2015 during a strong El Niño. All Enewetak specimens (first photo) were under dead coral on lagoon reefs at depths from 1 to 5 meters. Sizes ranged from 4 to 7mm. The Sea Slugs of Hawaii site also figures this species.
The three photos below show a specimen found under a rock on a shallow seaward reef at Kwajalein Atoll on 11 November 2010.
The 5mm specimen below was found on a Kwajalein lagoon pinnacle on 10 October 2011.
The specimen below was under a rock on a Kwajalein lagoon pinnacle on 24 April 2014.
Another was on a Kwajalein midlagoon pinnacle on 27 July 2015. It is crawling on an empty bivalve shell.
The next few photos show animals found on a lagoon pinnacle that about 7 months previously had been badly damaged by a cargo ship running aground. Much of the coral was crushed into white rubble and rocks. In December 2015, much of the crushed coral was still white, but quite a lot had been covered by algae, which was being grazed by numerous parrotfish and tangs. Some growth, small sponges, bryozoans and quite a few hydroids, had begun growing on the undersurfaces of the rocks, and a number of small eolid species were found, including a pair of this Eubranchus.
