-50m, North coast, Colombia, 46.4mm., 1996/vi
Tenorioconus granarius ranging from Panama to Venezuela is widely accepted as a subspecies of the beautiful Caribbean cone T. mappa; although sometimes considered a full species. It can be differentiated from other subspecies of T. mappa by its reduced colour patches, whitish grey to violet base colouration, high spire; and usually strong granulation as the name suggests. The deeper water specimens tend to have a taller spire (shown). It is a carnivorous and predatory vermivorous gastropod which mainly feeds on polychaete worms, such as fireworms (family Amphinomidae). A somewhat uncomm.on species, it inhabits sandy to muddy bottoms around -3-50m deep. Individuals aggregate to mate and spawn in the summ.er months of June to August, then depositing egg masses on hard substrates such as rocks or dead corals. Typical shell length around 50mm., extremely large specimens may exceed 70mm.
