Hemiphagidae

Hemiphagidae is a proposed family of sea snails, specifically marine gastropod mollusks. This classification is part of the superfamily Buccinoidea, which encompasses a wide array of whelks and their allies. The family Hemiphagidae was established to group certain species that exhibit unique anatomical and evolutionary characteristics distinguishing them from other members of Buccinoidea.

The proposed members of Hemiphagidae are generally characterized by their carnivorous feeding habits, preying on other invertebrates. Their shells often display a fusiform or ovate shape, with a prominent spire and a moderately long siphonal canal. The aperture is typically elongated and may possess a parietal callus.

Research into the phylogenetic relationships within Buccinoidea has led to the re-evaluation of existing taxonomic groups. The establishment of Hemiphagidae reflects an attempt to create a more accurate and monophyletic classification based on molecular data and morphological analyses. However, the status of Hemiphagidae as a distinct family is still a subject of ongoing scientific debate and may vary among different taxonomic authorities. Further research is crucial to solidify its position within the gastropod family tree.
