noidae

Noidae is a family of marine gastropod mollusks, commonly known as whelks, belonging to the order Neogastropoda. This family is characterized by its distinctive shell shape, which is typically ovate to elongate-ovate, with a smooth or slightly sculptured surface. The shell aperture is usually large, and the columella is often folded or plicate.

Noidae are found in various marine habitats, including rocky shores, coral reefs, and sandy bottoms. They are known for their slow, deliberate movement and their ability to burrow into the substrate. The family includes both herbivorous and carnivorous species, with some species feeding on algae and others on small invertebrates.

The taxonomy of Noidae is complex, with many species and subspecies described over the years. The family is further divided into several subfamilies, including Noinae, which includes the type genus Noa, and Fissurellinae, which includes the genus Fissurella.

Noidae are of interest to both scientists and collectors due to their unique shell morphology and ecological roles. They play an important role in marine ecosystems, both as predators and as prey for other marine organisms. Despite their ecological significance, many species of Noidae are threatened by habitat destruction and overfishing, making conservation efforts important for their preservation.
