- Data (± SD) for days to complete metamorphosis (DTM), snout-vent length (SVL), weight (W) and condition factor (k) for each egg mass (1–5) is shown. Means that are significantly different are indicated by different letters (p<0.05). Abbreviations: N, total number out of 75 Gosner Stage 25 embryos in the group that survived to metamorphosis (% survival is shown in parentheses), DTM, days to metamorphosis; SVL, snout-vent length; W, weight; k, condition factor; %Fert, percent fertilization.
