Figure 19 in Ontogeny of the skeleton of Moenkhausia pittieri (Ostariophysi: Characiformes) with discussion on functional demands and ossification patterns in the Characidae

Figure 19. Sequence of ossification of Moenkhausia pittieri, highlighting the following complexes: (1) neurocranium: olfactory region (yellow), orbital region (orange), otic region (red) and occipital region (burgundy red); (2) splancnocranium: jaws (pink), hyopalatine arch (violet), hyoid arch (dark purple) and branchial arch (purple); (3) axial skeleton: post-Weberian (light blue) and Weberian bones (dark blue); (4) paired fins: dark green (pectoral) and light green (pelvic); (5) unpaired fins: caudal (brown), anal (light brown) and dorsal (beige); and (6) opercular series (light grey), orbital series (medium grey) and sclerotic (dark grey). A, early stages, showing bones that start to ossify from 3.4 mm notocord length (NL) to 6.2 mm standard length (SL). B, later stages, showing bones that start to ossify from 6.6 mm SL onwards.
