Figure 18 in Ontogeny of the skeleton of Moenkhausia pittieri (Ostariophysi: Characiformes) with discussion on functional demands and ossification patterns in the Characidae

Figure 18. Sequence of ossification of the skeleton of Moenkhausia pittieri. A, early stages, showing bones that start to ossify from 3.4 mm notocord length (NL) to 6.1 mm standard length (SL). B, later stages, showing bones that start to ossify from 6.2 mm SL onwards. The thin vertical lines represent lengths (NL and SL, in mm) at which ossification can be present or absent. The thick horizontal lines represent the fixed presence of ossifications.
