Abstract

An overgrowth of muscle protruded through the ventral portion of the sixth abdominal segment of Penaeus aztecus and P. setiferus. This hamartoma was observed in 33 postlarval shrimp and is the first reported from a crustacean. Even though afflicted individuals represented a small proportion of the shrimp examined, nearly all such individuals were collected from the presumed most heavily polluted site. We suggest an unidentified pollutant as the cause of the abnormality.
