The family Camptandriidae currently comprises 40 species and 22 genera from South Africa, West Africa, New Caledonia and North-East Asia. Most species of Camptandriidae live in seas, tidal areas, estuaries and mangroves. Camptandriidae were formerly classified as a subfamily of Ocypodidae, but are currently considered a separate family. The Camptandriidae genus Deiratonotus Manning & Holthuis, 1981, comprises only three species: Deiratonotus cristatus (De Man, 1895), Deiratonotus japonicus (Sakai, 1934) and Deiratonotus kaoriae (Miura, Kawane & Wada, 2007)
The type locality for the description of Deiratonotus japonicus is Kagoshima. Deiratonotus japonicus is endemic to Japan. The crab is listed as a potentially endangered species by the Japanese Ministry of the Environment. The crab is not included in the IUCN Red List.
Description: Carapace transversely hexagonal, dorsal surface covered with fine, matted granules, uneven due to furrows on liver and gill regions, but not crossed by transverse ridges; regions generally well demarcated. Frontal margin slightly wider than orbit, distinctly bilobed; upper orbital margin slightly convex, transverse; outer orbital angle triangular and projecting anteriorly; lateral margins with two indistinct lobules behind outer orbital angle. Meri of walking legs rather slender.
The crab lives in isolated locations and in upstream brackish waters from Kanagawa Prefecture to Okinawa Prefecture in Japan
It can be found in habitats with coarse sand and pebbles, often hidden under stones and debris or in crevices and corners.
Unfortunately, no information is available on the diet of Deiratonotus japonicus..
