Sisyphus with a Hat

A bit of help in identifying this crab, please? Photographed on the beach at Casablanca, Morocco, late February 2020 (little knowing how the world would change within a week or 2!). I have had no luck using the usual sources. Not much more than 10 cm / 4" in size. Obviously a shorecrab, but which species?

@louisffourie I don't have time to look it up at the moment but there may be some entries on iNaturalist? Otherwise I suppose it's Grapsidae but wouldn't be sure any lower than that

@jopabinia There doesn't seem to be a lot of online sources for that part of the world that I can find. Although it is conceivable that the same species might occur in Portugal and Spain too.
