Fig. 2. Intraspecific scaling patterns of cephalopod molluscs. (A) Three published
intraspecific scaling curves for benthic octopods are drawn with the
interspecific pattern from Fig.
1. (B) Intraspecific scaling relationships are similar to
intrafamilial relationships in Fig.
1. Colors and lines represent different families. Loliginidae,
solid blue; Ommastrephidae, broken blue; Octopodidae, broken red;
Histioteuthidae, solid red; Cranchidae, long broken red; Bolitaenidae, solid
black; Vampyroteuthidae, broken black. (C) Intraspecific scaling coefficients
(b from Eqn 1 in text) are significantly higher (less negative) for
epipelagic squids (grey bar; Loliginidae and Ommastrephidae) than for
mesopelagic cephalopods (black bar) (N in parentheses; values are
means ± s.d.). Gonatids are not shown because the relationship between
oxygen consumption and body mass was not significant (b
0.0). See
Table 2 for equations and
sources.
