More than one hundred well-preserved specimens of a cancrid crab, Cancer gibbosulus (De Haan), were found on about 2m2 of a bedding plane in the Pleistocene Higashiyatsu Formation (0.4Ma). The crabs were found embedded in living position on the mud bed

The cancrid crabs from the Neogene and Quaternary deposits of West Japan are clarified. Mi- zuhocancer Karasawa, a new monotypic genus is proposed for Cancer? imamurae Imaizumi, 1962, previously assigned to Platepistoma Rathbun, 1906, by Karasawa (1993).

Due to recent eutrophication, oxygen-poor water develops annually near the bottom of Ise Bay, central Japan, in summer to autumn. This study examined seasonal and interannual variations in the abundance, biomass and distribution of megabenthos in the

Microplastics, emerging contaminants in the ocean, are thought to sink and accumulate in sediments, and thus may pose a potential ecological risk to benthic communities. In this study, abundances and characteristics of microplastics in sediments and benthic
