The Arctic whelk, scientifically known as Buccinum polare, is a fascinating marine creature found in the cold waters of the Northern Atlantic and Arctic regions. This unique gastropod not only plays a significant role in its ecosystem but also holds cultural and economic value for various communities. Its distinct shell and characteristics make it an interesting subject for marine enthusiasts and researchers alike.
Buccinum polare can be identified by its conical shape and relatively small size, typically reaching a maximum length of around 6.7 cm. The species thrives in benthic environments, where it can be found on the ocean floor, and is known for its adaptability to different depths and temperatures. This adaptability contributes to its wide distribution across both the Arctic and Northwest Atlantic.
Understanding the Arctic whelk's habitat and its role in the marine food web enhances the appreciation of this species. Local populations often utilize this whelk in traditional crafts and culinary dishes, making it an important part of their heritage and economy.
Key Takeaways

Identification Guide
Identifying the Arctic Whelk, known scientifically as Buccinum polare, involves recognizing its unique features and distinguishing it from similar species. This guide will cover key identification traits and important comparisons.How to Identify an Arctic Whelk
To identify an Arctic Whelk, one should look for a shell that is usually robust and has a smooth texture. The shell can vary in color from brown to yellowish or even white, depending on the habitat. The size typically reaches about 100 mm but can be larger in some cases. The aperture of the shell is often oval-shaped, with a slight curve. Inspecting the whorls is also crucial; they tend to be rounded and spaced evenly. A gentle spiral pattern may be present on the shell surface, contributing to its distinct look.Characteristics

Comparison to Similar Species
When comparing the Arctic Whelk to similar species, several features stand out. The Pacific Whelk (Buccinum crispum) has similar size but differs in shell texture, which is less smooth and more ribbed. Another closely related species is the Sinistral Arctic Whelk, which can also be found in Arctic waters. This whelk displays a sinistral (left-handed) shell twist, unlike the Arctic Whelk's dextral (right-handed) twist. It is important to examine the shell’s aperture and shape to make an accurate identification. Recognizing these differences can help in accurately identifying the Arctic Whelk in various marine environments.Distribution & Habitat
The Arctic Whelk, or Buccinum polare, is primarily found in cold ocean waters. Its range spans the Northern Atlantic and Arctic regions, highlighting its preference for cooler environments.Where to Find Arctic Whelk
Arctic Whelks live in a range of depths from 2 to 400 meters below the surface. They inhabit benthic zones, which means they are found on or near the ocean floor. This species can be found from approximately 82°N to 44°N latitude and longitudes between 162°W and 63°E. Key locations include:- Northern Atlantic Oceans: Common areas include Greenland and Iceland.
- Arctic Ocean: They thrive in the icy waters around Canada and Russia.
