More than 40 percent of Salton Sea females also lack the first tooth. Approximately equal but very small proportions of both males and females fail to develop all three dorsal teeth, or the development is delayed until full adulthood. Recapitulating the results (tables 1-2) by counting the number of possible and actual teeth present in each of the three populations results in a trend from 8 per cent of the teeth being present in Chesapeake individuals, through 82 per cent in Mississippi individuals to 60 per cent in Salton Sea individuals. Although the imbalance of dissolved salts in the Salton Sea may be a partial explanation for the phenotypic abnormalities of dorsal teeth in.
