Crisilla galvagni is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae. [1]

Contents

Crisilla galvagni is a species of minute sea snail, a marine gastropod mollusc belonging to the family Rissoidae . Like other members of the genus Crisilla , it is classified as a micromollusc due to its very small shell size. The species is part of the diverse rissoid fauna commonly found in Shallow water marine environment habitats across parts of the northeastern Atlantic and Mediterranean regions. [2]

Taxonomy

The species was originally described during taxonomic revisions of rissoid gastropods and has since been retained within the genus Crisilla based on shell morphology and anatomical features typical of the group. [3] [4] [5]

Description

Crisilla galvagni is a micromollusc, generally measuring only a few millimeters in length. [6] Its shell is:

Like other rissoids, the soft body is adapted for crawling on hard substrates, with a well-developed head, tentacles, and operculum. [7]

Distribution

The species is known from parts of the Mediterranean Sea and possibly the adjacent northeastern Atlantic . Records generally associate it with:

Exact distribution ranges vary between regional marine surveys, as micromolluscs are often under-sampled due to their small size.

Habitat and Ecology

Crisilla galvagni inhabits shallow marine ecosystems, usually living:

As a grazer, it feeds on microalgae, biofilm, and organic detritus, playing a small but significant role in coastal benthic food webs.

Conservation Status

There is no targeted conservation assessment specifically for Crisilla galvagni . However:
