Its distribution spans across a wide geographical area, including the coasts of Indonesia, Australia, and the Philippines. It is a prominent inhabitant of the tropical and subtropical marine zones, particularly those characterized by warm, clear waters.

Taxonomy

Lyria cassidula belongs to the family Volutidae, which comprises a diverse group of sea snails commonly known as volutes. This family, in turn, is classified within the order Neogastropoda, a group of predatory gastropods. These snails are further categorized under the class Gastropoda, a vast and diverse class within the phylum Mollusca. This taxonomic hierarchy underscores the evolutionary relationships and shared characteristics of this species with other gastropod mollusks.

Feeding

Lyria cassidula is a carnivorous species, primarily feeding on other marine invertebrates, such as worms, crustaceans, and other smaller mollusks. It utilizes its radula, a tongue-like structure equipped with rows of teeth, to scrape and capture prey. The feeding habits of this species contribute to the balance and stability of marine ecosystems.
