This is a red rock crab.
Nice full egg clutch of a female Dungeness crab!
This is a Bairdi, not Opilio.
Not a Dungeness crab, but a shore crab.
That is not a Dungeness crab...it is difficult to tell, but may be a naked shore crab or an invasive Asian shore crab...or some other shore crab.
I believe the first picture you have is of a naked shore crab, but the second one is definitely a Dungeness crab.
These look like some sort of land crab.
That is a European green crab, an invasive species to the United States. It is a voracious predator and competes for habitat with native shore crab.
