Heavy metal levels in Nucella lapillus (gastropoda: prosobranchia) from sites with normal and penis-bearing females from New England
Pseudohermaphroditism, as manifested by reproductively normal females possessing non-functioning penises, has been reported for more than thirty species of dioecious neogastropods. This anomaly was shown to be unrelated to age or parasitism, but the geographic distribution of this phenomenon indicated that it was environmentally induced rather than genetically controlled. In a survey of N. lapillus populations along the New England Coast, Pondick found abnormal females at sites directly under the influence of industrial discharges, sewage effluent, or vessel-related activities. Histological sections revealed the presence of a penial duct. The purpose of this study was to determine if there were differences in metal levels in the snail populations studied by Pondick, with particular attention to metals associated with boating activity.
