The tanaidaceans are a group of around 1,500 known species of mostly small (0.5 to 2 cm long) Peracarida that occur worldwide. They are mainly marine and benthic (bottom-dwelling), but a handful of species live in brackish or nearly fresh water. They often live in burrows or tubes and are known from ocean depths ranging from coastal (1 to 2 m) to around 9000 m. Many are suspension feeders, but some are detritivores or predators.
classified into 35 families
