There are more than 40,000 species of gastropods in the world. Oregon is home to at least 124 species of land slugs and snails — and here are 22 of them.
From giant banana slugs to tiny snails with delicate spiral shells, Oregon’s gastropods come in an astonishing range of colors, shapes and textures. Some are major garden pests. Others help break down decaying vegetation and recycle nutrients back into the ecosystem.
