small, up to a few millimeters long. Tanaidaceans are distributed worldwide, with more
than 1,200 described species. Following the first taxonomic paper on a Japanese
tanaidacean in 1936, many researchers have studied their taxonomy, morphology,
reproductive biology, or ecology in the waters around Japan. This chapter presents a
brief introduction to tanaidaceans and then reviews what is known of their systematics
(taxonomy and phylogeny), biology (including feeding habits, phenology, morphology,
reproductive modes, parasites, predators), and ecology in Japan. The chapter ends with a
summary and prospects for future research. The general conclusion is that tanaidaceans
have been under-studied, both globally and within Japan; the 104 nominal species
reported from around Japan and the 1,200 species reported globally likely represent a
fraction of the actual diversity. The phylogeny of tanaidaceans is largely unresolved at
all taxonomic levels. Recent, significant new discoveries dealing with herbivory, selfing,
skin-digging activity in holothuroid hosts, possible sound production, and tube building
suggest that much remains to be learned about their general biology.Springer2017engbook partAMhttp://hdl.handle.net/2115/81780https://doi.org/10.1007/978-4-431-56432-4_232509-55362509-5544Species Diversity of Animals in Japan603627https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/81780/1/Kakui_Chapter_603-627.pdfapplication/pdf627.69 KB2017
