Figure 2.
Numbers of marine Isopoda (except Asellota and crustacean symbionts) in biogeographic regions.
A. In 12 MEOW biogeographic realms for 2851 species with minimum depths of <800 m. The few species known to occur in >1 realm are assigned only once on the basis of type locality. B. In 14 GOODS lower bathyal provinces for 202 species with minimum depths >800 m. More detailed data for families are given in Tables 2 and 3. No species are known to occur in >1 province.

Figure 4.
Bathymetric ranges of species of the larger families (and groups of related families) of marine isopod families.
Data come from Schotte et al. [2], gaps filled by data from original publications. Species are ranked, left to right, from shallowest minimum depth to deepest, with depth records <10 m coalesced as 10 m for clarity. Numbers of species of each family or family group for which data are readily available are given. Green dots are average depths. Vertical axes are depths in metres, not to the same scale.
