365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Toothless
Day 166: We have quite a few species of snail in the Pacific Northwest and among the most common is Allogona townsendiana, the Oregon Forest Snail. The shell is brown and marked with thin, light lines when these snails are young, but the colour is only a papery layer which peels off in age, revealing a blue-white base. That said, Allogona can be confused with other species in age, and the most definitive feature for field identification is the absence of a tooth-like structure in the aperture. The Oregon Forest Snail is quite toothless!
