Buccinum
Buccinum is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Buccinidae, the true whelks. These snails are found in cold and temperate waters of the northern hemisphere.
Characteristics
- Shell: The shell of Buccinum species is typically thick and spiral-shaped. Shell morphology varies considerably between species, but generally features a prominent siphonal canal. The shell surface can be smooth or have spiral ridges and tubercles. The color is often a mottled pattern of brown, gray, or white.
- Size: The size of Buccinum whelks varies depending on the species, but they can range from a few centimeters to over 10 centimeters in length.
- Habitat: Buccinum whelks inhabit sandy or muddy bottoms in shallow coastal waters and deeper offshore environments.
- Diet: Buccinum species are primarily carnivorous scavengers, feeding on dead animals, polychaete worms, and other invertebrates. They are attracted to carrion.
- Predators: Buccinum whelks are preyed upon by various marine organisms, including crabs, fish, and seabirds.
- Reproduction: These snails reproduce sexually, with males fertilizing the eggs of females. Egg capsules are often laid in clusters attached to rocks or other hard surfaces.
Economic Importance
Some Buccinum species are commercially harvested for human consumption, particularly in Europe and Asia. They are often marketed as "whelks" and are a popular seafood item. The shells are occasionally used for decorative purposes.
Species
The genus Buccinum contains numerous species, including:
- Buccinum undatum (Common whelk)
- Buccinum cyaneum (Arctic whelk)
- Buccinum scalariforme
