Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae). [PDF]

J Morphol
In this study, we provide the first complete description of the skeleton ontogeny of an anostomid. The developmental sequence of 141 bony elements is described and illustrated. The main discoveries are numerous conical teeth on the premaxilla and dentary that are replaced with three or four large incisiform multicuspid teeth, that become unicuspid in ...
