The whiting also reveals a feature in which the Teleostomi (with the exception of some ganoids) are unique among Vertebrata—namely, that the oviducts are continuous with the ovaries. The bony flat fishes (Soles, Plaice, etc.) are related in general features to the whiting, but are flattened—not, as is the skate, from above down-.
