Description
Size: Max length 36.0 cm ML (male)

Max. weight reported: 1.8 g

Color: The dorsal side is darkish due to crowding of chromatophores, the ventral side is less pigmented. The general colouration in fresh specimens is pinkish brown, with whitish ventral side, the base of the eyes and the surroundings have a greenish tinge, on the dorsal surface of the mantle and fins greyish transverse streaks are found which are conspicuous in males.

The mantle is elongate, conico-cylindrical and tapering to a rounded blunt point posteriorly. Anterodorsally the mantle extends over the neck region as a small rounded point; the ventral margin at mantle opening is emarginated. The fins are characteristically very large and wide, extending from the anterior margin of mantle to the posterior end. The fins are very thick and muscular. The head is large, eyes prominent and greenish at the base, funnel is large and provided with prominent funnel valve. The tentacles are moderate in length and stalks are stout and slightly laterally compressed; clubs are large and provided with trabeculate protective membranes on the sides. Suckers arranged in four rows transversely, those in the middle rows are larger than the lateral ones; horny rings of large club suckers have 14 to 23 teeth as in arm suckers.
