Here's a summary of the order from Drumm et al (2006): "Tanaidaceans are usually considered to be a minor taxonomic group of Crustacea (Malacostraca: Peracarida). Most are small (2-5 mm long) but adults range in size from 0.5 - 120 mm. A few may be found in freshwater, but most are marine and brackish water forms. The majority of the 1200+ species have been reported living at depths exceeding 200 m; some have been reported at depths exceeding 9000 m. In some deepwater environments, Tanaidacea are the most diverse and abundant fauna present. Although relatively few species have been reported from estuaries, they are often ecologically significant in such systems."
