Below are examples of snails you are likely to run across if you spend any time at all on Oregon’s exposed rocky shores. All photos are from northern Oregon unless otherwise noted in the caption. My organization follows Lamb an Hanby (2005). Common names are my choice. I refer to WoRMS for scientific names, and I learn a ton by browsing the natural history riches in Kozloff (1993). Biodiversity of the Central Coast’s molluscs page is full of great information about most of the species shown below, and they are covered in the books, field guides, and identification resources listed at the bottom of the page.

Lirabuccinum dirum, dire whelk

I haven’t run across dire whelks on my home beaches in northern Oregon. These are from sheltered Salish Sea waters.

Tegula funebralis, black turban

Black turbans are conspicuous and abundant. The seem a bit more numerous on the central Oregon coast than on my home beaches in northern Oregon, but that could just be the places I frequent.

Dave Cowles’ page on back turbans is full of additional information.
