Red Data Book on Land and Freshwater Mollusks is revised and published. This Red Data Book is based on the Red List (List of Endangered and Threatened Species in Japan) published in 2000 and detailed information is supplemented including morphology, habitat distribution and condition for each species listed. This Red Data Book is a revised version for land and freshwater mollusks included in Red Data Book: Endangered Wild Life in Japan-Invertebrates published in 1991.
