Key to Invertebrates Found At or Near The Rosario Beach Marine Laboratory

This page serves as an entrance to a fascinating look at many of the marine invertebrates found in Puget Sound and the Straits of Juan de Fuca, Washington. Each species has a special page with its description and notes about its natural history, plus observations we have made of the species. Most of the photos were taken of live animals, either in the field or in the lab on animals that were then returned to the field.
