Mean citrate synthase activity in mantle muscle declines significantly with increasing minimum depth of occurrence (m) in Califor- nian (solid circles, solid line; v = ; ' 23±0-32; r2 = ; P = ; n = 9) and Hawaiian (open circles, dashed line; y = *"' '"; r2 = ; P = ; n = 10) pelagic cephalopods. For comparison, mantle muscle CS activity for Loligo opalescens is also shown (X; units g *; Ballantyne et 1981). Depth There was a strong decline in mean mantle muscle CS activity with increasing minimum depth of occurrence (Fig. 3) in species from both California (v = ~' ?2; r •• ; P •• = ; /; 9) and Hawaii (v *~106±057; r = ; P = ; n = 10). There was also a strong decline in mean ODH activity with in- creasing MDO (Fig. 4) in species from both California (y = X loV'54±a41; r2 = ; P = ; n = 9) and Hawaii (v = X 10VL60±1"; r' = ; P = ; n = 10). There were not significant relationships between CS or ODH and MDO in tin or arm tissue for either California.
