Stygra

Stygra is a genus of small, marine snails belonging to the family Muricidae, commonly known as murex snails. These snails are found in the Indo-Pacific region and are characterized by their typically small size and elaborate shell ornamentation. The shells of Stygra species often feature prominent spines, ridges, and tubercles, which can vary in prominence and arrangement depending on the specific species and environmental conditions.

The diet of Stygra snails consists primarily of other invertebrates, such as bivalves and polychaete worms. They are predatory and use their radula, a ribbon-like structure with teeth, to bore into the shells of their prey or to rasp away soft tissues. Reproduction in Stygra, as with other muricids, involves the laying of egg capsules, which are typically attached to hard substrates. The larval development can be direct or involve a planktonic stage.

While not as widely known or commercially exploited as some other murex species, Stygra snails play a role in their marine ecosystems as predators. Their shells, though small, can sometimes be collected by enthusiasts due to their intricate designs. Research on Stygra primarily focuses on their taxonomy, distribution, and ecological interactions within their specific habitats.
