Blue Swimmer Crab Yellow Curry Soup 🥘 This crab has a cute purplish blue color, they live more in the sea so the taste is more savory and sweet but its size is smaller than other crabs. Indonesians usually call it "rajungan ungu". They are very rarely found here if it is not in season like now. I read quite a lot about them because I like them, I almost want to keep them at home because they are cute but it's better to cook them. In my stomach they are safer 😅
