I went to supermarket to invite some friend to have lunch ( i'm newby like cooker ) , and I found and I bought it. But this colour make me confuse, usually the dead octopus are grey not brown. The woman who sell to me, said it is "Rock octopus". For me it is a common Mediterranean Octopus vulgaris, but it is fishend in Morocco, and the colour... Now maybe it is glucose and proteins It tastes good!!!
