Figure 1: Motility and growth of West African Dwarf crocodile (Osteolaemus tetraspis) embryos incubated at 28 °C or 32 °C (n = 3 per group) and euthanised at E70, approximately hatching age.
From: Limb proportions show developmental plasticity in response to embryo movement
(a) Individuals from the 28 °C (left) and 32 °C (right) groups, demonstrating large differences in growth. Scale bar = 20 mm. (b) Number of embryo movements per 3 minute monitoring period during mid- to late incubation. (c) Body (snout to vent) length upon euthanasia. (d) Limb length. (e) Relative limb length (% snout-cloaca length). (f) Limb element lengths (% total limb length). Values are shown as mean ± SEM and were analysed using Welch’s t-test. *Indicates P < 0.05, ***indicates P < 0.001.
