Survivorship curves for Experiment 1 comparing Pagurus larvae fed oyster larvae, a control group fed Artcmia nauplii, and an unfed control group. Below the survivor- ship curve is a bar graph indicating the time during which molting occurred and the mean time to molt. against the maxillae, maxillules and mandibles. The mandibles "chew" the nauplius, but generally only one or more appendages are removed before the nauplius escapes. Late stage zoeae are more efficient, but still rarely ingest an entire nauplius. Fecal production was undetected during the early stages, pronounced in late Zoea III and Zoea IV. The Artemia-ied control group always exhibited a high rate of survival. Experiment 1 was terminated after day 7 and when 53% of the remain- ing larvae had reached the third instar. In Experiment 2, 31% of the larvae reached the megalopa after a mean of days, in Experiment 3, after Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
