Fig. 2 Photomicrographs of lateral views (A,B,D) and ventral views (C,E,F) of sucker mutant embryos reveal that Meckel’s cartilage (lower jaw) is strongly reduced or absent. The diagram (F) represents a composite of elements photographed in C and E. The neurocranium is omitted. The ceratohyal is reduced and fused to the basihyal (E). Although the posterior arches are present, they are reduced. Ventral to the ceratohyal additional unidentified plate-like cartilaginous elements can be detected (C,F). Scale bars: 200 μm (A); 100 μm (B-F).
