Fish morphants staged at 24 hpf show eyes reduced in size, and dark and opaque zones in all brain structures. In addition, the otic vesicle and the midbrain/hindbrain border regions are barely detectable. Cartilage and bone staining reveals underdevelopment of craniofacial cartilage, bone alterations, and clefting of the lower jaw. The third through sixth pharyngeal arches are underdeveloped in morphants. {ECO:0000269|PubMed:24360810}. |
