Hapellisia

Hapellisia is a genus of marine snails belonging to the family Muricidae, commonly known as murex snails. These gastropods are characterized by their elaborate shells, which often feature spines, frills, or other decorative projections. The species within the Hapellisia genus are typically found in shallow to moderately deep waters of tropical and subtropical oceans, particularly in the Indo-Pacific region.

The diet of Hapellisia snails generally consists of other invertebrates, such as bivalves and polychaete worms, which they prey upon by drilling through the shells of their victims. Their reproductive habits are typical of many marine gastropods, involving external fertilization and the laying of egg capsules.

The exact taxonomic classification and number of species within Hapellisia have been subject to revision as new research emerges. Some species previously assigned to Hapellisia may now be classified under different genera, and vice versa, reflecting the ongoing study of marine mollusks. Their distinctive shells have made them of interest to shell collectors, although their ecological roles are more significant in marine ecosystems.
