Frequencies (%) of individuals with altered counts, individuals with deformed shape, and individuals with both altered counts and deformed shapes of bones underwent indirect ossification (i.e., endo- or perichondral ossification), per lot.

When the observed value is 0, the cell has been left empty to make easier the reading.N = number of individuals considered, per lot; n.c. = data not collected; codes in brackets indicate the anomalies considered (see Table 2).1hypurals are reported to ossify endochondrally in zebrafish (Danio rerio) [78]–[80], in Senegalese sole (Solea senegalensis) [80], in gilthead seabream [81] but other authors found that ossification is perichondral in Nile tilapia and desert pupfish [82];2parahypural (a ventral support of caudal fin) is reported [82] as undergoing perichondral ossification, but also that it ossifies endochondrally [71].
