Akera bullata, named the royal flush sea slug, is a species of sea snail (or sea slug), a marine opisthobranch gastropod mollusk in the family Akeridae, a family that is related to the sea hares. This species is the only European representative of the genus Akera.




Distribution


This species occurs from Norway to the Canaries, and also in the Mediterranean.




Ecology


This is a herbivorous bottom dweller (up to 370 m deep), which feeds on seagrasses in the genera Zostera and Posidonia.




Description


The body of this sea hare can reach a maximum length of about 6 cm. Its coloration varies from gray to orange, often with white or dark specks. The shell is fragile, smooth, and can be either white or brown. This sea hare is not an agile swimmer. When disturbed, it uses its broad parapodia — fleshy protrusions held together in a funnel shape above the head — to paddle away.
