Gemmula reticulata is a species of sea snail, a marine gastropod mollusk in the family Clathurellidae, within the superfamily Conoidea. Like many members of the Conoidea, these snails are predatory and possess a venom apparatus.

The genus name Gemmula means "small gem," possibly referring to the often ornate shells of its members. The species epithet reticulata is derived from Latin, meaning "reticulated" or "net-like," referring to the distinctive pattern on its shell.
Description The shell of Gemmula reticulata is typically fusiform (spindle-shaped) with a moderately high spire. It can reach lengths of approximately 20 to 50 millimeters. A key characteristic is its prominent and intricate sculpture, which consists of strong axial (longitudinal) ribs intersected by equally strong spiral cords, creating a distinct reticulated or net-like pattern across the whorls. This pattern is particularly evident on the teleoconch (adult whorls).
The shell color varies but is often a light brownish or yellowish hue, sometimes with darker banding or blotches. The aperture (opening) is relatively narrow, and the outer lip is usually thin, with a distinct anal sinus (a notch near the suture, characteristic of Conoidea). The siphonal canal is distinct and moderately long.
Distribution and Habitat Gemmula reticulata is found in the Indo-Pacific region. Its geographic range includes areas off Japan, the Philippines, Indonesia, and parts of Australia, among others. It typically inhabits subtidal to bathyal depths, often found on sandy or muddy substrates on the continental shelf and slope, usually in waters deeper than 50 meters.
Ecology As a member of the Conoidea, Gemmula reticulata is a carnivorous predator. It preys on other invertebrates, often using a specialized radula tooth to inject venom into its prey. While the specific diet of G. reticulata is not always extensively documented, other species within the genus Gemmula are known to feed on worms or other small soft-bodied marine organisms. Its deep-water habitat suggests it plays a role in the benthic food web of these environments.
