Kurodaconus is a synonym of the subgenus Conus (Turriconus) Shikama & Habe, 1968,n represented as Conus Linnaeus, 1758. These are of sea snails, marine gastropod mollusks in the family Conidae, the cone snails and their allies.^[1]

Distinguishing characteristics edit

The Tucker & Tenorio 2009 taxonomy distinguishes Kurodaconus from Conus in the following ways:^[2]

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.^[2]

The former genus Kurodaconus Shikama & Habe, 1968

Shell characters (living and fossil species)

The shell is pyriform with angulate shoulders and an elevated scalariform spire. The protoconch is multispiral. Nodules are obsolete. The anal notch is moderate in depth. The periostracum is smooth, and the operculum is moderate in size.

Radular tooth (not known for fossil species)

The anterior section of the radular tooth is much shorter than the posterior section, and the blade is absent. A basal spur is present, and the barb is short. There are a minimal number of serrations.

Geographical distribution

The species in this genus are found in the Indo-Pacific region.

Feeding habits

Unknown at this time.^[2]
