The individual shown was exposed to 0.1 ppb atrazine. Abbreviations: K, kidney; O, ovary; UO, unpigmented ovaries. () The entire dissected, Bouin’s-fixed kidney–interrenal–gonadal complex. Although the individual shown has distinct lobes, some animals with this morphology had only very shallow indications of lobes. () A transverse cross-section (8 μm) through the geometric center of the animal’s kidney and gonads. The section is stained in Mallory’s trichrome stain. This histology revealed that the animals were in fact females, even though their gonads lacked pigment, typical of normal ovaries. Scale bar: () 0.1 mm; () 40 μm.
