Montagu's / Furrowed crabs

Observation - Montagu's / Furrowed crabs. Description: I found several of these medium sized (6cm wide carapace) crabs of quite variable colour recently in Cornwall with a smoother outline to the carapace than shore crabs and big muscular looking claws. I think they have to be Montagu's crabs aka Furrowed

I found several of these medium sized (6cm wide carapace) crabs of quite variable colour recently in Cornwall with a smoother outline to the carapace than shore crabs and big "muscular" looking claws. I think they have to be Montagu's crabs aka Furrowed crabs. Their latest scientific name is Lophozozymus incisus but also known until recently as Xantho hydrophilus or X. incisus (NBN has it as that). Mostly far SW and west coast of UK.
