Thus, the respiration rates increased with increasing body mass and habitat temperature, but decreased with increasing depth. By the definition of dummy variables, respiration rates of the taxonomic categories for which regression coeffcients were not significant (p > 0.05. blanks in Table 2) are equivalent to the rates of Loliginidae (Lo) for cephalopods and Myctophiformes (My) for fishes. Among the 16 designated taxonomic categories (families and orders) for cephalopods, Ommastrephidae (OM) and Gonatidae (Go)
exhibited consistently higher respiration rates regardless of the choice
of body mass units, while Cranchiidac (Cr), Histiateulthidae (His),Vainpyrnteucliidae (VA), and Octopoda (Oc) exhibited lower respiration
rates on the basis of WM units only ( the latter three orders/families) or
WM, C and N units (Cranchiidae)
