The embryo of a wild type zebrafish above the embryo of banp mutant zebrafish, both four days post fertilization (dpf). The mutant embryo has smaller eyes compared to the wild type (shown with the red arrow). The black arrow shows cloudy tectum (the uppermost part of the midbrain) in the mutant embryo, which represents cell death. Scale bar = 100 μm. The image appeared in the research paper published in eLife.
