Gladioconus is a synonym of a subgenus of sea snails, marine gastropod mollusks in the genus Conus, family Conidae, the cone snails and their allies.^[1] T

Distinguishing characteristics

The Tucker & Tenorio 2009 taxonomy distinguishes Gladioconus from Conus in the following ways:^[3]

Genus Conus sensu stricto Linnaeus, 1758

Shell characters (living and fossil species)

The basic shell shape is conical to elongated conical, has a deep anal notch on the shoulder, a smooth periostracum and a small operculum. The shoulder of the shell is usually nodulose and the protoconch is usually multispiral. Markings often include the presence of tents except for black or white color variants, with the absence of spiral lines of minute tents and textile bars.

Radular tooth (not known for fossil species)

The radula has an elongated anterior section with serrations and a large exposed terminating cusp, a non-obvious waist, blade is either small or absent and has a short barb, and lacks a basal spur.

Geographical distribution

These species are found in the Indo-Pacific region.

Feeding habits

These species eat other gastropods including cones.^[3]

Subgenus GladioconusTucker & Tenorio, 2009

Shell characters (living and fossil species)

The shell is obconic to turbinate in shape, with broad shoulders. The protoconch is multispiral, and the whorls have nodules which may persist or become obsolete. The body whorl is typically ornamented with ridges. The anal notch is fairly deep, except in smaller specimens. The color patterns include brown or red banded shells, and rarely mostly white shells. The periostracum is tufted, and the operculum is small.

Radular tooth (not known for fossil species)

The anterior sections of the radular tooth is longer than or similar in length to the posterior section. The blade is long, and is more than half as long as the anterior section of the tooth. A basal spur is present, the barb is short, and there is an internal terminating cusp. The radular tooth has coarse serrations.

Geographical distribution

The species in this genus occur in the West Atlantic and Eastern Pacific regions, and one species is endemic to the Marquesas Islands.

Feeding habits

These cone snails are vermivorous, meaning that the cones prey on polychaete worms.^[3]
