Below are examples of sea cucumbers I’ve run across on Pacific Northwest shores. It’s a scant list. 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 Echinoderms page is full of great information on cucumbers. These cucumbers, at least Cucumaria miniata, are also covered in the books, field guides, and identification resources listed at the bottom of the page.
Cucumaria miniata, orange sea cucumber- I don’t know much about orange cucumbers; haven’t come across them on my home beaches in northern Oregon. They’re sure a splash of color.
I startled this one by turning over its sheltering rock | Orcas Island 
Laying out in a sheltered niche at low tide | Galiano Island
