| Abstract |
Embryos of the inland silverside, Menidia beryllina, were exposed to a nominal concentration of 50 micrograms terbufos/1 during the first five days of embryogenesis. Silversides were maintained in clean dilute seawater until 37 days after hatching. Radiographs revealed compressed and fused vertebrae and dorsal-ventral misalignment of pre- and postzygapophyseal processes. Histopathological examination of individuals exposed to terbufos during embryogenesis revealed various vertebral lesions ranging from small hyperostoses to almost complete fusion of some vertebrae. |
