While we originally considered this a possible young specimen of Cerberilla annulata, it may also be a young specimen of C. asamusiensis, known from Japan, Indonesia and the Philippines. The first photo shows a small 15mm specimen found on 18 June 2012 in a shallow lagoon Halimeda patch. Our specimen does not closely match those on the Sea Slug Forum, but it is quite close to one figured on the Slug Site.
When asecond specimen was found on the Kwajalein Atoll seaward reef at night, it was initially seen hanging from a mucus thread from a ledge at a depth of about 26m.
