Description
A small chromodorid up to about 15 mm in length. The body is white. The mantle margin is bordered by a translucent white band, with an interrupted purple line running just inside that band. The rhinophores have a transparent stalk with a white tip, with only the lamellae (perfoliations) coloured red. The gill plume is white with the rachis and gill lamellae both red.Distribution
Widespread across the tropical Indo-Pacific. Originally described from material from the Hawaiian Islands. Records include South Africa, Australia, Indonesia, Papua New Guinea, the Philippines, New Caledonia, Japan, the Marshall Islands, Midway Atoll, and the Hawaiian Islands.Etymology
The specific epithet daniellae is the feminine genitive of a Latinised personal name Daniella, indicating dedication to a person named Daniella (or a related feminine name). The Japanese vernacular "Daniel-iro-umiushi" is built on the same name transliteration (danielae → danieru).References
