Natica livida is a species of sea snail, a marine gastropod mollusk in the family Naticidae, commonly known as moon snails.
Description and Characteristics
Natica livida is a relatively large species of moon snail, with individuals typically reaching a maximum size of 50 millimeters in shell length. The shell of Natica livida is generally smooth and glossy, with a characteristically rounded shape. The color of the shell can range from pale brown to dark brown, often with a faint white or cream-colored band around the periphery.
Habitat and Occurrence
Natica livida is found in a variety of marine environments, primarily along the coasts of the Indo-Pacific region. It is commonly found in intertidal and shallow subtidal zones, often inhabiting sandy or muddy substrates. The species exhibits a preference for areas with moderate wave action and moderate salinity levels. Natica livida is also known to inhabit coastal lagoons and estuaries, demonstrating its adaptability to a range of marine environments.
Taxonomy
Natica livida belongs to the Class: Gastropoda, which encompasses a vast diversity of snails and slugs. This group is further categorized within the Order: Littorinimorpha, a large order of marine snails that exhibit a wide range of adaptations and ecological roles. Within this order, Natica livida is a member of the Family: Naticidae, a group of predatory snails commonly known as moon snails. This family is characterized by their distinctive, often glossy and smooth shells.
Feeding
Natica livida is a carnivorous predator, primarily feeding on other marine mollusks, particularly bivalves. It uses its strong, muscular foot to burrow into the sediment and locate its prey. Once it finds a bivalve, Natica livida utilizes its radula, a ribbon-like structure with rows of teeth, to drill through the shell. After creating an opening in the shell, Natica livida secretes digestive enzymes into the bivalve’s body, effectively liquefying the soft tissues. The snail then consumes the liquefied flesh through the hole it created.
