Abstract Analyses of individual content of carbon (C), nitrogen (N), and hydrogen (H) were carried out for all larval stages of Pagurus bernhardus and Carcinus maenas, and for newly metamorphosed crabs. Maximum range in total larval development is 12.8 to 165.8 μg C, 3.2 to 35.1 μg N, and 1.9 to 24.9 μg H in P. bernhardus and 3.1 to 43.2 μg C, 0.7 to 10.1 μg N, and 0.4 to 6.3 μg H in C. maenas. From these data energy equivalents were calculated. Maximum range in total larval life is 0.43 to 6.38 J ind. -1 in P. bernhardus and 0.1 to 1.49 J ind. -1 in C. maenas. There is a 32.4% mean loss of energy in P. bernhardus megalopa development; this seems to describe the normal developmental pattern in this stage. Biomass was determined as fresh and dry weight respectively. Individual dry weight is about 3.6 to 5.6 times higher in P. bernhardus (44 to 340 μg) than in C. maenas (12 to 93 μg) larvae.
