Toxicity of mercury during the embryonic development of Chasmagnathus granulatus (Brachyura, Varunidae)
Ovigerous females of the estuarine crab Chasmagnathus granulatus were exposed to mercury (0.1 mg/L) during the entire, early, or late embryonic development. A delay in the egg incubation period and some morphological abnormalities were detected in larvae hatched from exposed females. Particularly, h...
