Stylocheilus is a genus of sea slugs, specifically sea hares, marine opisthobranch gastropod mollusks in the family Aplysiidae, the sea hares.[2][3]

According to some authors this genus belongs in the family Dolabriferidae.

Species

Species in the genus Stylocheilus include:

  • Stylocheilus polyomma (Mörch, 1863)
  • Stylocheilus rickettsi (MacFarland, 1966)
  • Stylocheilus striatus Quoy & Gaimard, 1832
    • Distribution : Indo-Pacific; intertidal, occurs up to 30 m depth
    • Length : 65 mm
    • Color : brownish, with blue spots; lined species, with dark longitudinal lines (as stated by its name striatus) and small eyespots, providing excellent camouflage.
    • Description : Feeds on blue-green algae; gives off a purple ink when disturbed.
Taxon inquirendum
  • Stylocheilus longicauda Quoy & Gaimard, 1824 - Blue-ring Sea Hare, Lemon Sea Hare (used to be called Stylocheilus citrina)
    • Distribution : circumtropical, Indo-West Pacific.
    • Color : bright yellow or green with bluish eyespots, no lines.
    • Description : This is one of the most specialized sea hares; elongate body with a long "tail" (as stated by its name longicauda), adapted for living on floating seaweed; feeds on Mermaid's Hair, blue-green algae of species Lynghya majuscula; at times, they are abundant, with several thousands crawling in the sand, traveling in chains ("snail trail") up to 10 m long
