Colonization of the deep sea by fishes.

Priede IG, Froese R - J. Fish Biol. (2013)

Bottom Line: The slopes for the Classes Myxini (-0·000488) and Actinopterygii (-0·000413) follow this trend but Chondrichthyes decrease more rapidly (-0·000731) implying deficiency in ability to colonize the deep sea.Within the Actinopterygii, there is a trend for greater invasion of the deep sea by the lower taxa in accordance with the Andriashev paradigm.Deep-sea invasive families such as Ophidiidae and Liparidae make the greatest contribution to fish fauna at depths >6000 m.

The relationship between log10N (N = number of species within a 500 m depth stratum) and depth (x) for three classes of fishes with fitted regression lines: Myxini () log10N = −0·000488x + 1·760000 (r2 = 0·965), Chondricthyes () log10N = −0·000731x + 3·070000 (r2 = 0·954) and Actinopterygii () log10N = −0·000413x + 3·550000 (r2 = 0·944).

fig01: The relationship between log10N (N = number of species within a 500 m depth stratum) and depth (x) for three classes of fishes with fitted regression lines: Myxini () log10N = −0·000488x + 1·760000 (r2 = 0·965), Chondricthyes () log10N = −0·000731x + 3·070000 (r2 = 0·954) and Actinopterygii () log10N = −0·000413x + 3·550000 (r2 = 0·944).

Mentions: There was an overall trend of logarithmic decrease in species number with depth described by the fitted regression equation: all marine fish species log10N = −0·000422x + 3·610000 (r2 = 0·948), where N is the number of species maximum depths per 500 m depth stratum and x is the depth (m). Similar trends were seen for the individual classes (Fig. 1).
