Abstract
Length-weight relationships, feeding rates, and surface area and morphology of the third and fourth thoracic limbs of Daphnia carinata and Ceriodaphnia quadrangula s.l. were examined. Weight (W) increased between the square and cube of body length (L). W= 7.88 × 10-7 L2.23, W= 1 .7 × 10-6 L2.26 for D. carinata and C. quadrangula s.l., respectively. Both cladocerans had small (
