|Classification according to Bouchet et al. (2017)|
Taxonomic source: World Register of Marine Species (AphiaID: 828313).
Body soft to the touch, colored white with pink shades, orange or red, with darker spots on the back. Mantle covered with long caryophyllic tubercles (400 microns) arranged tight and evenly, giving it a velvety appearance. Spicules very long. There are some groups of white caryophyllic tubercles surrounding a longer (500 microns) white tubercle. The caryophyllic tubercles of the dark spots are pigmented with the same dark tone. The sides of the body have a lighter shade than the dorsum color, but they are darker than the sole of the foot. The foot has the same dimensions as the dorsum, it has a groove on the anterior side and the upper lip cleft. The oral tentacles are long and finger shaped. The rhinophores are colored a lighter shade than the rest of the body, almost depigmented but with tones of beige, light pink or pale yellow. They have from 12 to 14 lamellae each, the lower ones incomplete because they do not join in the rear, and with brown spots in the distal lamellae. The mucron (apical end of the rhinophore) is white. The rhinophoric sheath is large and has caryophyllic tubercles similar to those on the mantle, but spread out. The gill has 9 bipinnate leaves forming a circle around the anus in a frustoconical arrangement with the pinnas joined on the inner side; they have the same color as the mantle but with the tips of the pinnae with white or yellow spots. The branchial sheath has caryophyllic tubercles with white tips spread along the edge. The anal papilla has the same color as the body.
The spawn is a 5-6 mm high ribbon wound spirally, with capsules containing one or two yellowish white or pink spherical eggs, of 65-70 microns in diameter. Although mantle texture and coloration are characteristic, Jorunna efe could be confused with Jorunna onubensis, with which it is sympatric, as both species have been cited for the Canary Islands. Apart from internal anatomical details (radula and genitalia) that differentiate them, the structure of the gill and the caryophyllic tubercles of the mantle, much shorter in Jorunna onubensis, allow to distinguish them in plain view.
- Efe, to the Spanish News Agency (EFE) because of the 75th aniversary of its foundation (that took place on 1939).
Found in the Azores and the Canary Islands, also in Morocco (Al Djadida) and the shore of Granada (Spain) in the Mediterranean (Sánchez-Tocino, 2003 and 2011). Wirtz (1999) reports it from Madeira as Jorunna onubensis.
