Cancellaria
Cancellaria is a genus of medium-sized to large sea snails, marine gastropod molluscs in the family Cancellariidae. They are commonly referred to as “Cancellarias” or “Netted Shells” due to their distinctive shell patterns. These snails are found in a variety of habitats, from shallow coastal waters to deeper, offshore environments, predominantly along the Atlantic and Pacific coasts of the Americas and the Indo-Pacific regions.
Characteristics
Cancellaria shells are typically elongated and spindle-shaped, with a pointed spire and a wide aperture. They exhibit a characteristic reticulated, or net-like, pattern, formed by the intersection of axial (vertical) and spiral (horizontal) ridges or cords. These ridges can vary in prominence and density, creating a unique texture and appearance for each species. The shells are typically white, cream, or brown in color, often with darker bands or markings.
The body of the Cancellaria snail is typically soft and elongate, with a muscular foot and a prominent siphon. They are carnivores, feeding on other marine invertebrates, such as worms and crustaceans. The snails use their radula, a ribbon-like structure in their mouth, to scrape and tear their food.
Environment
Cancellaria species are found in a range of marine environments, including:
- Shallow subtidal zones
- Intertidal zones
- Deeper water environments on continental shelves and slopes
- Sand, mud, and rocky bottoms
Some species are associated with specific habitats, such as seagrass beds or coral reefs. They are often found buried in the sediment or under rocks, using their siphon to sense prey.
