Figure 5

Circulating lactate in (a) intact and (b) eyestalkless Neohelice granulata exposed for 45 min to three different dissolved oxygen concentrations (0.7, 2 or 6 mgO2·L−1) and injected with physiological saline (CTR) or melatonin (2, 200 or 20,000 pmol·crab−1). Each point represents the mean ± SE (n = 4–7). Different letters represent significant differences (p < 0.05) between the groups with the same dissolved oxygen concentration. * represents a significant difference (p < 0.05) from the CTR group at 6 mgO2·L−1.
