By 144 hpf, considerable growth of the entire hyosymplectic has occurred compared to its size at 96 hpf. Also, ossification of the hyomandibula (hm) bone has increased in the perichondrium of the hyomandibula region of hyosymplectic (hs) along the ventral surface of the facial nerve (VII) foramen (ff) compared to that seen at 120 hpf. The relative positioning of the hyosymplectic with the articulating opercle (op), otic capsule (ot), interhyal (ih), and palatoquadrate (pq) has not changed significantly from that seen at 96 hpf.
