Identification Guide
The Arctic Moon Snail (Cryptonatica affinis) can be identified by distinct features and specific characteristics. Recognizing these traits is important for understanding its role in the ecosystem.
How To Identify An Arctic Moon Snail (Cryptonatica affinis)
To identify the Arctic Moon Snail, observe the shell shape and color. The shell is smooth and glossy, usually ranging from white to pale yellow or light brown. It can be up to
59 mm in height and
48.7 mm in diameter. The shell often has a rounded base with a distinct pattern of ridges or spirals. The aperture, or opening, of the shell is large, allowing a view of the soft body inside. It thrives in cold, Arctic waters and can be found at depths up to
2,660 meters.
Characteristics
The Arctic Moon Snail is a carnivorous species, feeding mainly on bivalves. Its body color can vary but often appears gray or brownish. The snail has a
well-developed foot that allows it to burrow into the substrate. Its reproductive strategy involves laying small eggs enclosed in capsules, allowing direct development. This adaptation helps protect the eggs in harsh marine environments. Notably, it lacks a large operculum, a feature found in some other snail species, making it easier to differentiate.
Comparison To Similar Species
When comparing Cryptonatica affinis to similar species, look for differences in shell size and habitat. For example, the
Pale Northern Moonsnail often has a thinner shell and prefers rocky intertidal zones. Another similar species,
Natica clausa, can be distinguished by its more pronounced spiral ridges.
