Phidiana lottini
(Lesson, 1831)

Family: Glaucidae


South America - west coast


Antofagasta region, northern Chile. Depth approx 60ft. Photos: Marcelo Krause.

This species has usually been identified as Phidiana inca (d'Orbigny, 1837) but Schroedl (1997) considers P. lottini to be the oldest name for the species. It is a large translucent white species, with opaque white tips to the oral tentacles and the sparsely lamellate rhinophores, with a white V pattern on the head formed from a line running from the tip of each oral tentacle to a patch between the rhinophores. A white medio-dorsal line runs from the rhinophores back down the body. The cerata have a white tip followed by a broad orange band. Below this band the ceratal wall is transparent, the black or dark brown digestive gland showing through the ceratal wall.
