Brief Description
A medium-sized predatory sea snail commonly found in the intertidal zones of the Pacific Northwest.
Characteristics
It features a thick, heavy shell with prominent spiral ridges or ruffles (frills). Colors vary from white and cream to orange or brown, sometimes with banding.
Habitat
Rocky intertidal zones, specifically the mid-to-lower tide levels on protected and semi-exposed shores.
When to Find It
Visible year-round, but most active and seen forming breeding clusters in late winter and spring.
Conservation Status
Common
Ecological Role
They are important predators in the intertidal community, primarily feeding on barnacles and mussels, which helps regulate those populations.
Easily Confused With
Often confused with the Channelled Dogwinkle (Nucella canaliculata) which has deeper, smoother grooves, or the Northern Striped Dogwinkle.
Observation Tips
Look in tide pools and under rock overhangs during low tide. Handle gently and always return to the spot and orientation where you found it.
Interesting Facts
This species is highly polymorphic, meaning its shell shape and frilliness change significantly depending on if it lives in wave-beaten areas or calm waters.
