Overview

Limaria orientalis, commonly known as a file shell, is a bivalve mollusc belonging to the family Limidae. It is a suspension feeder often found in shallow marine environments, where it may live in large aggregations.

Appearance

This species features a thin, fragile, and oblique oval-shaped shell that is typically white in color. The exterior is marked by fine radial ribs, with secondary ribs developing in the interspaces as the animal grows. The hinge line is straight with prominent auricles at each end, and the interior of the shell is white with a crenulated margin.

Biology & behavior

Limaria orientalis is a facultatively mobile bivalve that can create nests using mucus. It is known to inhabit fine silty sand and mud substrates, often seeking shelter in the crevices of rocks or reefs. In some regions, it is considered a naturalized species, having potentially been introduced via shipping activities. It reproduces sexually and is capable of suspension feeding to obtain nutrients from the water column.
