Cool wrecks. Painted greenling and a huge kelp greenling. Back deep in the hole was the largest Puget sound king crab I've ever seen. I mean massive body. Tons of perch to.
Yea, not 100% but the spines and shell were not that of a red or dungie. I'd put money on it being a pskc.
Heart crab maybe?
If it was it would be a record breaker. Carapace was like almost 2 feet. Spiny, short arms not like tanner and way to shallow. Wish I had a camera.
Cool! I haven't heard of a pskc that south before!
