Shortening of the anterior-posterior axis of mutant zebrafish heads. a) A scheme demonstrating the anterior-posterior length measures done for zebrafish. The head length was defined as the length measured between the middle of a virtual line crossing the plan posterior to zebrafish eyes (in red) and the zebrafish most anterior part (blue arrowed line). Zebrafish body length was measured from the edge of the caudal fin to the zebrafish most anterior part (not shown in scheme). All measures were done using image J software. b) A graph showing a significant shortening of the anterior-posterior axis of mutant zebrafish heads.
