Marianina rosea (Pruvot-Fol, 1930)
Maximum size: about 10 mm.
Identification:
This is a distinctive species with a bright violet body, white bifid
cerata and orange-tipped rhinophores.
Natural history:
Marianina rosea
feeds on hydroids, unlike most tritoniids. We haven't seen it on Maui
but it appears to be more common on Oahu and the Big Island where it occurs at moderately
protected sites. A Big Island animal was found at 12 m (40 ft).
Distribution: Big Island and
Oahu: widely distributed in the Indo-Pacific.
Taxonomic notes:
Some authors place this species in its own family, the Marianinidae. It
was first recorded in Hawaii from Oahu by Gustav Paulay in Dec. 2008.
