Filodrillia ordinata is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.[1] This species was first described by Charles Francis Laseron in 1954.[2] It is known for its distinct shell morphology and its occurrence in specific marine environments.
Description
[edit]The shell of Filodrillia ordinata is relatively small, with a height that can reach up to 7.7 mm.[3] The shell is characterized by its elongated, fusiform shape and intricate patterns. The coloration of the shell can vary, but it typically features a combination of light and dark hues that provide camouflage against the seabed.[4] The surface of the shell is adorned with fine spiral ridges and grooves, which add to its intricate appearance. The aperture is narrow, and the outer lip is thin and slightly flared.[5]
The shell's structure is adapted to its marine habitat, providing protection against predators and harsh environmental conditions. The species exhibits a high degree of morphological variation, which is common among marine gastropods and is influenced by environmental factors such as water temperature, salinity, and substrate type.

Distribution
[edit]This marine species is endemic to Australia and occurs off New South Wales, Tasmania and Victoria. This region is known for its rich marine biodiversity and complex oceanographic conditions. The species inhabits shallow to moderately deep waters, typically at depths ranging from 10 to 50 meters. The cold, nutrient-rich waters of these regions provide an ideal habitat for Filodrillia ordinata, supporting its growth and reproduction.
The distribution of Filodrillia ordinata is influenced by various oceanographic factors, including currents, temperature gradients, and the availability of suitable substrates. The species is often found in association with other marine organisms, forming part of a diverse and complex ecosystem.[6]
Habitat and Ecology
[edit]Filodrillia ordinata is adapted to life in marine environments. It is a benthic species, meaning it lives on or near the seabed. The species is typically found on soft substrates such as mud and sand, where it can burrow and find food. Filodrillia ordinata is a carnivorous species, feeding on small invertebrates and detritus. It uses a specialized radula, a toothed, chitinous ribbon, to scrape food from surfaces.
The species plays an important role in the benthic ecosystem, contributing to the balance of predator-prey relationships and the recycling of organic matter. Its presence indicates a healthy and functioning marine ecosystem, as it is sensitive to changes in environmental conditions.
