spider crab

Observation - spider crab - UK and Ireland. Description: See in approx 3m of water. I often see Spiny Spider Crabs but this one was more knobbly than spiny, it had decorated itself with weed, which seems unusual and it was smaller than the ones I usually see. Is it a different species, sea toad maybe?
