Movie 3.

Motility of olfactory pit cilia of a wild-type zebrafish embryo. Coordinated metachronal beating of multiple cilia on MCCs of the olfactory pit. In this and all subsequent videos of olfactory pit cilia motility, embryos imaged were at 72 hpf and the focal plane is at the surface of the olfactory pit. Videos were captured at 100 fps and is played at 30 fps. Scale bar = 20 μm.
