3 dpf sp7:EGFP Alizarin red	Lateral Movie(s): 3 dpf opercle lateral movie
Description	By 72 hpf, the opercle (op) consists of a linear spicule of bone matrix surrounded by tightly packed osteoblasts. The opercle articulates along its dorsal tip with the hyosymplectic cartilage (not visible here) through a ball and socket joint. At this time, opercle growth occurs ventrally through the addition of osteoblasts in a linear fashion that parallels the existing bone (data not shown). Faint EGFP-derived fluorescence throughout the image is derived from transgene expression in the ectoderm.
