Recovery frequency of the external morphology of the severe lordotic individuals at 4 and 7 dpe (a–c) and valorization of the scoring methodology by means of double staining (d–g) at the end of the recovery period (7 dpe). (b, c) Representative case of the transition of a juvenile from a typical lordotic (s-L) to a recovered (s-L/rec) external morphology respectively. (e–g) Representative cases of the internal bone structure of a severe lordotic (s-L), a light lordotic (l-L) and a recovered (s-L/rec) individual after double staining (ds) respectively. Scale bars equal to 1 mm. n, individual number assessed. Asterisks indicate significant differences (p < 0.05).
