Dolabrifera (Gray, 1847) is a genus of sea hares, a taxonomic group of sea slugs or marine opisthobranch gastropod mollusks belonging to the family Aplysiidae.
A more general description can be found on the page of the superfamily Aplysioidea.
Species within the genus Dolabrifera
- Dolabrifera dolabrifera Cuvier, 1817
- Distribution : circumglobal; tropical and subtropical waters.
- Length : 4 cm
- Color : varies greatly between individuals and populations, mostly between beige and mottled green, but pink and chartreuse green has been spotted; this offers a good camouflage against the background.
- Description : rather flat mantle with a broad posterior, narrowing towards the head; fused parapodia, except for a short region in the posterior midline; eggs are zigzag-shaped ribbons, pink when laid then changing color to brown before hatching; moves in a unique way, like a leech; feeds mostly by grazing on filamentous algae.
- This species is frequently sold as "algae eating sea hare" at aquarium stores for saltwater and reef tanks.
