TABLE 3. Comparative data found during the early development of Brachyplatystoma. Roman numerals identify the spines, Arabic numerals indicate the branched fin rays, myomeres, and proportions. *Characters better observed from the postflexion stage. Data from Lundberg & Akama (2005), Leite et al. (2007) and Silva et al. (2022).
