C. sp. 34 develops more slowly than C. elegans. Synchronized populations of C. elegans (A, B) and C. sp. 34 (C, D; for both species, average N worms = 107 ± 32.2 SDM; range = 23–445), were monitored hourly for the fraction of actively molting animals (A, C) and the fraction of L4 larvae and adults (B, D). Populations were synchronized at the L1 larval stage 12 hours apart and monitored concurrently to capture the full progression of development (i.e., animals were not monitored for 24 hours a day). Arrowheads in (A) and (C) represent the maximal molting fractions corresponding to the likely major molting events.
