Description

edit

The length of the shell reaches a length of 14 mm, and a diameter 5 mm. Inquisitor shibanoi, a species within the family Pseudomelatomidae, is a marine gastropod with a unique, elongated shell structure, displaying fine spiral sculpturing.[2] The species belongs to a broader genus, Inquisitor, characterized by its slender and often sharply conical shells with notable axial ridges that aid in identification within its family. As with other members of its genus, Inquisitor shibanoi has a pointed apex and a well-defined siphonal canal, both distinctive features of predatory gastropods in this group.[3]

Distribution

edit

Fossils of this marine species were found in the Higashi-Innai Formation in Japan. Primarily found in the Indo-Pacific region, particularly near Japan, Inquisitor shibanoi resides in subtidal zones where it inhabits soft substrates. The species’ distribution patterns align with many Pseudomelatomidae family members, favoring continental shelf environments, often in moderate depths where it can prey upon other marine organisms.

Ecology and Feeding Habits:

As a carnivorous snail, Inquisitor shibanoi preys on smaller invertebrates, using a specialized radula to capture and consume its prey. Its predatory behavior aligns with the ecological role of Pseudomelatomidae, which often regulate populations of smaller mollusks and crustaceans in their habitats, contributing to marine biodiversity balance.
