Cubaris murina is a small terrestrial isopod (woodlouse) in the family Armadillidae, notable for its ability to conglobate—roll into a complete ball when disturbed. The species reaches approximately 11 mm in length and 5 mm in width. It has a remarkably broad geographic distribution spanning tropical and subtropical regions across multiple continents, with populations in the Caribbean, South America, Southeast Asia, and the Pacific. The species has become popular in the exotic pet trade due to its bioactive utility in terrariums and the development of several color morphs through selective breeding.
