These are sea snails, marine gastropod mollusks in the family Conidae, the cone snails and their allies.[1] Distinguishing characteristicsThe Tucker & Tenorio 2009 taxonomy distinguishes Kioconus from Conus in the following ways:[2]
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]
Shell characters (living and fossil species) The shell is obconic with flat sides and carinate shoulders. The spire is only slightly scalariform. The protoconch is multispiral. The shell is ornamented with well developed cords on the whorl tops, and nodules which may persist or die out early. The anal notch is moderate to deep. The periostracum is tufted and ridged, and the operculum is moderate in size. Radular tooth (not known for fossil species) The anterior section of the radular tooth is roughly equal in length with the posterior section, and the blade covers between one-third to more than half the length of the anterior section. A basal spur is present, the barb is short, and the denticles are coarse. Geographical distribution The species in this genus occur in the Indo-Pacific region including Australia and South Africa. Feeding habits These cone snails are vermivorous, meaning that the cones prey on polychaete worms.[2] Species listThis list of species is based on the information in the World Register of Marine Species (WoRMS) list. Species within the genus Kioconus include:[1]
