Regression statistics pelagic cephalopods and fishes derived from stepwise (forward selection, Pin=Pout=0.05) multiple regression analyses of routine respiration rates ( R:µlO2 individual-1 h-1 ) on body mass [BM, in terms of wet mass (WM), dry mass (DM), carbon (C) or nitrogen (N), all mg] habitat temperature (Temp, K) and habitat depth (Depth, m) [Model(1)], and plus 16 orders/families for cephalopods [Model (2)], or 15 orders for [Model (3)].
