Anetarca

Anetarca is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.

Anetarca species are characterized by their cancellate shells, meaning the shell surface is marked by a lattice-like pattern of intersecting spiral and axial ribs. They are generally small to medium in size, with a fusiform (spindle-shaped) shell. The aperture is typically ovate, and the outer lip may be lirate (lined with ridges) internally. The columella (the central pillar of the shell) usually has one or more oblique folds.

Anetarca snails are found in various marine habitats, including sandy or muddy bottoms, often in deeper waters. They are carnivores or scavengers, feeding on other invertebrates or organic detritus.

The taxonomic classification of Anetarca and related genera within the Cancellariidae family has been subject to revision, and ongoing research continues to refine our understanding of their phylogenetic relationships. Further research may be necessary to fully clarify the species composition and distribution of this genus.
