Cumulative numbers of marine fish.

Cumulative numbers of marine fish diversity (n = 633, Appendix 6.2) in the Arctic Ocean and adjacent seas (AOAS) from 1758 to the present. Species are broadly grouped according to zoogeographic pattern (cf. Section 6.3.1): Arctic (A, blue symbols) and non-Arctic (Σ AB, B, WD, red symbols). Grey bars denote periods with many descriptions of new Arctic species. Note that 75% of the non-Arctic species known to science were described by 1912, whereas the same proportion for Arctic species was only reached in 1976. See text for further information.
