Fig. 8
(a to d) Histological sections of the Senegalese sole larvae at 30 dph, showing the different retinal layers from controls (a), and from 1.56 (b), 3.12 (c) and 6.25 (d) μg/L malathion exposed organisms. Note reduction in size as well as in thickness of the pigmentary epithelium; e Changes in pigmentary layer thickness (μm) in response to the different treatments; Eye size corrected for total body length of larvae at 20 (f) and 30 (g) dph; Changes in the longest eye diameter at 20 (h) and 30 (i) dph in response to the different treatments. Different letters indicate statistically significative differences between treatments. (* = P < 0.05; ** = P < 0.01). Scalebar represents 100 μm
