Slugs and Snails in Oregon
|
There are 124 species of terrestrial molluscs (slugs and snails) in Oregon. Except for the beloved banana slug, most native snails and slugs go unnoticed as they feed on plants, fungi, or an array of decaying organic material. A few are predators. Their alien nature can be fascinating — legless hermaphrodites, love darts, tails that can be lost like a lizard’s, and plenty of mucus. This guide is designed to help identify the most commonly encountered slugs and snails in Oregon. For each genus or species, a brief description is provided that includes information about size, pest status, and whether it is native or exotic.
