Diversity of Tanaidacea (Crustacea: Peracarida) in the World's Oceans – How Far Have We Come?
Figure 4
Numbers of species by four depth-bands for most families of the Tanaidacea (some monotypic families excluded for clarity), arranged by suborder.
The four depth bands are essentially littoral to shelf, slope, lower bathyal to upper abyssal, and lower abyssal to hadal.
