Lyria cassidula, also known as the Cassidula Lyria, is a species of sea snail, a marine gastropod mollusk in the family Volutidae. It is characterized by its distinctive shell shape and coloration, making it an intriguing subject for marine enthusiasts and collectors alike.
Description & Characteristics
The shell of Lyria cassidula is typically ovate and slightly elongated, with a smooth, glossy surface. It exhibits a range of colors, often displaying a combination of browns, yellows, and oranges, sometimes with intricate patterns or markings. The aperture, or opening of the shell, is wide and oval-shaped, leading to a well-developed siphonal canal. The maximum size attained by this species is approximately 50 mm, making it a relatively small but nonetheless visually appealing species.
Habitat and Occurrence
Lyria cassidula is commonly found in a variety of habitats, primarily in the Indo-Pacific region. This species favors sandy or muddy bottoms, often residing at depths ranging from 5 to 50 meters. 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.
