Fig. 4
The development of otoliths in 5 dpf zebrafish larvae is visualized in this figure.
The schematic drawing of the lateral view of the zebrafish larvae shows the position of the ear and its otoliths (A) depicted in pink. These larvae were levitated for 1000 s (n = 31) or 2000 s (n = 27). No difference in otolith placement, number or diameter (Student’s t-test, p > 0.05) can be detected in either group when compared with control non-levitated animals (a–d). Open arrowhead indicates the smaller anterior otolith, and the closed arrowhead indicates the larger posterior otolith. Anterior of the fish is oriented towards the left and the dorsal of the fish towards the top of the page. Scale bar, 50 μm.
