Figure 5.
The photograph of an adult wild type zebrafish (A) was electronically modified to generate altered images in which body proportions (compressed (B) or stretched (C)), color (yellow (D) or red hue (E)), or stripe pattern (lack of stripes (F) or vertical stripes (G)) was manipulated. In each experiment animated (moving) images of five identically altered zebrafish were shown on one side of the experimental tank and moving images of five unaltered (wild type) zebrafish on the other. In addition, a set of five unaltered zebrafish images were also presented near the surface vs. near the bottom. For additional experimental details see Methods section.
