Cumulative number of tanaidacean species described in each decade since 1800.

Apseudomorphan adaptations. a, Kalliapseudes sp. with a filter-feeding apparatus on the chelipeds; b, Cyclopoapseudes sp., with a flattened body adapted to burying in the upper layer of soft sediments; c, Macrolabrum sp., with its twisted posterior thorax and abdomen, adapted to living inside empty snail shells, d; Tanzanapseudes sp., with a flattened body adapted to life on and between flat surfaces of coral rubble; e, Bunakenia sp with its pereopods adapted to digging in soft sediments.
Figure 3.
Diversity of forms in the Tanaidacea. a–b, g, various forms of males in the Leptocheliidae; c, female of Pooreotanais sp.; d, Arhaphuroides sp.; e, Sinelobus sp.; f, Anarthruridae indet.; h, Neotanais sp.; i, Metatanais sp.; j, Tanzanapseudes sp.
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.

Figure 6.
Cluster analysis of Bray-Curtis similarities (%) between various sea-areas, based on the numbers of species of tanaidacean genera (or higher taxa, see text) per region, for: a, shallow waters, <200 m depth, and: b, deep waters. A, B and C are clusters referred to in the text.
