Calliostoma vilvensi is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae. [2]
The shell of Calliostoma vilvensi is moderately tall and conical, with a height typically ranging between 12 mm and 23 mm. [3] It features a solid, non-umbilicate (imperforate) base and slightly convex whorls.
The species was described by the Belgian malacologist Guido Poppe in 2004. It was named in honor of Claude Vilvens, a fellow malacologist and expert on the superfamily Trochoidea. [1] Within the genus Calliostoma, this species is noted for its particularly elegant shell sculpture and vivid pearlescent interior.
This marine species is found within the Coral Triangle in the tropical Western Pacific. Known populations are located off:
It is a deep-water benthic species, usually found at depths between 80 m and 350 m. Most specimens are collected by local fishermen using tangle nets or by deep-sea dredging. [4]
Calliostoma vilvensi is similar in appearance to Calliostoma vicentweiri, but can be distinguished by its flatter base and the specific arrangement of the beaded cords on the upper whorls. Additionally, C. vilvensi often displays more pronounced reddish-brown flammules compared to the more uniform coloration of related deep-water species.
