Bathynomus
Giant Isopods, Supergiant Isopods, Sea Bugs (Vietnamese: bọ biển)
Bathynomus is a genus of supergiant deep-sea isopods in the family Cirolanidae, containing nearly 20 described species. These crustaceans are among the largest isopods in the world, with some species exceeding 30 cm in length and 1 kg in weight. They inhabit cold, deep waters of the Atlantic, Pacific, and Indian Oceans, typically at depths of 400–2,300 m. Several species have become commercially fished as seafood, particularly in Vietnam, where they are known as "bọ biển" or "sea bugs."
