Pusia zebrina

Pusia zebrina is a small sea snail with a shell length reaching up to 14 mm. The shell is oblong and slightly elongated, featuring a smooth surface except near the siphonal canal, where approximately ten striae can be observed. An obtuse ridge appears in this area, corresponding to a prominent tooth on the columella. The spire is elongated and conical, made up of six slightly convex whorls that are only faintly separated by a suture. The aperture is narrow and marked by three folds on the columella, along with a callosity on the spire's side. Its shell is characterized by a chestnut-brown color with a slight violet hue, which becomes paler at the suture and aperture, displaying small, evenly spaced whitish lines that wave longitudinally in a regular pattern. This marine species is found off the Canary Islands and Morocco, inhabiting coastal waters. While specific habitat preferences are not detailed, its presence at various dive sites suggests it may be associated with rocky or sandy environments. Encountering Pusia zebrina during a dive can be intriguing, as divers may spot these snails nestled among the substrate or on rocky surfaces. Pusia zebrina's diet and reproductive habits are not explicitly mentioned in the sources, leaving some aspects of its biology open to exploration. However, divers may appreciate observing the unique shell structure and coloration of this species while underwater.
