I think it’s a dungeoness. Green seaweed on it. Thought it might be the invasive species but don’t think so. [graceful crab LW 8/7/26]

Hi Scott, This one pictured is actually a native graceful crab. It has 10 marginal teeth and the area between its eyes even with it’s eyes (not protruding like red rock crabs do), but the 10th marginal tooth on Dungeness is the widest point, whereas on these graceful crabs, it’s actually that little notch tucked around the corner. You might enjoy flipping through these flashcards of our common cancer crabs to see some side-by-side: https://wsgcrabteam.uw.edu/wp-content/uploads/2026/04/MEGRvCAPRvMEMA-Slides.pdf – Lisa
