Giant size specimen Oliveragemmula cosmoi (Gemmula congener cosmoi), 60 mm, from Japan; authentic original and in good condition.
Description from the seller
Article description & scientific data
Scientific name: Oliveragemmula cosmoi (Sykes, 1930) – traditionally listed as Gemmula congener cosmoi.
Common name: Melvill's Turrid.
Quality level: GEM (absolutely perfect top condition; the slender, narrowed siphonal canal is completely intact, the pronounced pearl-bead row along the keel is razor-sharp preserved, the aperture and apex are flawless).
Size: 60 mm (6.0 cm) – large specimen! While regular pieces usually measure well under 50 mm, this specimen impresses with its rare, stately size at the absolute maximum range of the species.
Morphology: A classic elegant, tower-shaped shell. Characteristic is the cream-white to light brown base color with striking dark-brown spots arranged directly below the sculptured shell seam.
Family: Turridae (slit turrids).
Origin & Habitat
Geographic origin: Mikawa-Isshiki, Aichi Prefecture, Honshu, Japan (Pacific Ocean).
Habitat: A pure deep-water species. It lives benthically on sandy-silty soft substrates of the deeper continental shelf. The piece was brought to the surface by local deep-sea trawlers from spectacular depths of typically 100 to 300 meters.
