''Flabellina ischitana'' is a species of sea slug, an aolid nudibranch, a marine gastropod mollusk in the family Flabellinidae. ==Description== This species can grow to a length of approximately 4 cm and is mostly purple-violet in colour. It has opaque white-tipped certa, rhinophores, and oral tentacles. Due to the somewhat transparent skin of the ceras, the branches of the digestive gland are visible, and appear as red-orange. ''Flabellina ischitana'' is often confused with ''Flabellina affinis'', but can be distinguished as follows: *''Flabellina ischitana'': the ceratal surface has not purple-violet colouration and is translucent *''Flabellina affinis'': the digestive gland is not visible as the area beneath the subapical white ring is opaque 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Flabellina ischitana」の詳細全文を読む スポンサード リンク
