Calappa lophos, commonly known as the red-streaked box crab or the common box crab, is a species of box crab (Calappidae) endemic to the Indian Ocean and western Pacific Ocean, including Andaman Sea and the waters around Taiwan, Japan, and Australia. For years, this species has been widely ignored by most manufacturers, with only three examples by Kaiyodo in 2003 (Kurosio Komekko), 2013 (Capsule Q Museum), and 2018 (Aquatales).
