Giant isopods of the genus Bathynomus, which can reach more than 30 cm in length, are known as bọ biển or “sea bugs” in Vietnam. For the first time, one such species was described from Vietnamese waters and named Bathynomus vaderi. The name “vaderi” is inspired by the appearance of its head, which closely resembles the distinctive and iconic helmet of Darth Vader, the most famous Sith Lord of Star Wars.

Bathynomus vaderi belongs to a group known as “supergiants,” reaching lengths of 32.5 cm and weighing over a kilogram. So far, this new species has only been found near the Spratly Islands in Vietnam, but further research will probably confirm its presence in other parts of the South China Sea.

Giant isopods like Bathynomus vaderi have become an expensive delicacy in Vietnam. Until 2017, local fishermen only sold them as a bycatch product for low prices, but in recent years the media has drawn public attention to this unusual seafood. Some go as far as claiming it’s more delicious than lobster, the “king of seafood”.
