Item# 0003944025
FamilyNaticidae
NameSinum haliotoideum - Very Rare Operculum! , (Linnaeus, 1758)
Size18.8 mm, w/o
LocalitySingapore, Changi Beach
NoteGEM, W/O, W/P. Superb top quality with absolutely perfect lip and most importantly, it includes the very rare real operculum of this exact specimen. Specimen with operculum almost never offered as the small and fragile operculum is hidden among the live animal meat and easily break when removing it from the meat. The listing of this species with real operculum will change the misconception that Sinum has no operculum! Fully preserved complete yellowish periostracum. Hard to find complete periostracum for big specimen because periostracum usually peel off or incomplete. Found buried in muddy sand among sandflat during low tide, 6th Oct 2025.
