As its name suggests, the Moon Crab has a strikingly unusual appearance. Its shell is decorated with vivid red circular patterns blended with shades of soft pink—resembling the glowing face of the moon. Because of these round markings, islanders gave it the poetic name “Moon Crab.” With such a distinctive look, it quickly became one of the iconic specialties of this remote, peaceful island where the only constant sounds are the whispers of the ocean.
Moon Crabs live clinging to rocky cliffs along the shoreline. Their meat is not at its best during full moon days, when the crab becomes watery and less flavorful. But during the right season, their meat is extraordinarily sweet, firm, and fragrant—captivating anyone who tastes it.
When boiled, the crab turns a brilliant, fiery red that is almost impossible to resist. However, this is not a dish for the faint-hearted: the crab’s shell is extremely hard, so you’ll need proper crab-cracking tools to reach the tender, aromatic white meat hidden beneath its tough exterior.
The simplest and most delicious way to enjoy Moon Crab is to dip the meat in salt, pepper, and lime—a combination that enhances its natural sweetness. Locals also use Moon Crab to prepare a variety of dishes such as hotpots, soups, noodle bowls, or even banh canh (thick Vietnamese noodles). Regardless of the recipe, each dish becomes richer, sweeter, and more special thanks to the unique flavor of this extraordinary crab.
If you visit Con Dao, don’t miss the chance to try Moon Crab—one of the island’s most distinctive tastes, offering both an unforgettable culinary experience and a piece of its coastal charm.
