Vertebral Numbers of American Plaice, Hippoglossoides platessoides (Fabricius), in the Northwest Atlantic
Vertebral numbers of American plaice in the Northwest Atlantic are compared. Counts ranged from 42 to 48 vertebrae excluding the urostylar half-vertebra.No significant difference was found between vertebral averages of males and females.Averages for an area extending from the Northeast Newfoundland...
