Barnacles

Below are examples of barnacles you are likely to run across on Oregon’s exposed rocky shores, or maybe washed up on the beaches. The photos on this page are from northern Oregon unless, noted in the caption. My organization follows Lamb and Hanby (2005). Common names are my choice. I refer toWoRMS for scientific names, and I learn a ton by browsing the natural history riches in Kozloff (1993). Biodiversity of the Central Coast’s Crustaceans page is full of great information on all the barnacles shown below. These barnacles are also covered in the books, field guides, and identification resources listed at the bottom of the page.

Balanus nubilus, giant barnacle

Look for giants in the low intertidal or lower
