The
Tucker & Tenorio 2009 taxonomy distinguishes
Ductoconus 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
Ductoconus da Motta, 1991 ::Shell characters (living and fossil species) :::The shell is obconic. The
protoconch is multispiral with 2.5 whorls, and with nodules which persist on all whorls. The anal notch is fairly deep. The
periostracum is tufted and the operculum is large. ::Radular tooth (not known for fossil species) :::The anterior section of the
radula is much longer than the posterior section. The blade is short, a basal spur is present, and the barb is short. The
radular tooth has serrations and a terminating cusp which are both internal. ::Geographical distribution :::The only species in this genus occurs in the Eastern Pacific region. ::Feeding habits :::The only species in this genus is
vermivorous (meaning that the
cones prey on marine worms). ==Species list==
