European Green Crab (Carcinus maenas) on Jan 13, 2026

Submitter does not have a specimen

Description of specimen

I found 8 European green crabs while tide pooling on January 2, 2026. I’m a frequent visitor to this particular set of tide pools and have never seen them at this location over the last 4 years of regular visits. All of them were missing at least one claw and limbs.

Commentary

Avatar of commenter Thank you Mikalynn for this invasive Green Crab report! There are a number of different shore crabs commonly found in tide pools along the Oregon Coast. ODFW is fully aware of this invasive. You can follow the link to their website for further information or give the local district a call:
