The
Tucker & Tenorio 2009 taxonomy distinguishes
Kalloconus from
Conus in the following ways: • 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. • Subgenus
Kalloconus da Motta, 1991 ::Shell characters (living and fossil species) :::The shell is large and obconic with broad angulate shoulders slightly rounded on the edges. The
protoconch is multispiral. The anal notch is moderately deep to deep in larger specimens, and shallower in smaller specimens. The shell is ornamented with spots and dashes in spiral rows, and cords are either absent, very small and numerous, or die out early on whorl tops. The
periostracum is smooth and thin, and the operculum is moderate in size. ::Radular tooth (not known for fossil species) :::The anterior sections of the
radular tooth is substantially longer than the posterior section, and the blade is relatively short being one third to one-half the length of the anterior section. A basal spur is present, the barb is short. The radular tooth has a major row of serrations flanked by rows of smaller serrations. ::Geographical distribution :::The species in this genus occur in the
West African region to
Europe. ::Feeding habits :::These cone snails are
vermivorous, meaning that the cones prey on
polychaete worms. ==Species list==
