Fig. 25. Dependence of the rate of respiration R (meal /day per 

 individual) upon the body weight Wg (mcal/indiv.) in tropical planktonic 

 animals, a - crustaceans: 1 - Calanoida; 2 - Cyclopoida; 3 - 

 Euphausiacea; 4 - Mysidacea; 5 - Ostracoda; 6 - Hyperiidea; 7 - 

 Lucifer : b - other: 1 - Chaetognatha; 2 - Medusae; 3 - Ctenophora; 4 - 

 Siphonophora; 5 - Polychaeta; 6 - Pteropoda. 



regression line presented falls significantly below the line obtained 

 experimentally at 20°C. Thus, we can draw the preliminary conclusion 

 that the level of metabolism of tropical copepoda at 30°C is close to 

 the level of metabolism of crustaceans of the temperate latitudes at 

 20°C. This confirms once more the opinion that the metabolism of 

 animals at different latitudes is adapted to the environmental 

 temperature (Fox, 1936; Sholander et al., 1953; Pavlova, 1967;
