Conus distans   Hwass in Bruguiere,  1792 (Sea Snail)
Organism information awaits expert curation
Class: Gastropoda

Size: 65-137 mm

Color: Ground colour white. In smaller subadults, last whorl with olive brown clouds, base dark brown. During growth, clouded pattern changing to a band on each side of centre; bands either progressively occupying entire last whorl (Pacific populations) or secondarily reduced (Indian Ocean populations). Bands usually become less olive and base slightly lighter during growth. Teleoconch spire with blackish brown radial markings between tubercles (including large Indian Ocean shells without colour bands on last whorl). Periostracum blackish brown, thick, opaque, and rough in large adults from Philippines (L 130 mm) and lighter brown, thinner, with widely set spiral rows of strong tufts on last whorl and spire in subadults from Madagascar. A thick, olive-green or brown periostracum with tufted ridges around last whorl is reported from Hawaii (Kohn, 1959a) and Fiji (Cernohorsky, 1964).

Moderately large to large, solid to heavy. Last whorl conical, outline convex to strongly convex near shoulder, straight below. Shoulder variably angulate, tuberculate in smaller adults (up to 75-85 mm in length). Spire of low to moderate height, outline concave to convex. Postnuclear spire whorls tuberculate. Teleoconch sutural ramps concave, with 2-3 faint spiral grooves in middle ramps, and finer spiral striation on later ramps. In subadults, last whorl with broad spiral ribs at base, followed by about 5 widely set spiral grooves almost to adapical third with ribbons between. In large adults, surface smooth except for broad but faint spiral ribs at base.
