Morphological characteristics of shank3b −/− larvae and adult zebrafish. a–b Abnormal morphological changes in shank3b −/− and shank3b +/− larvae at ~ 1 dpf, including severe developmental delay, eye melanin reduction (blue arrow), and tail bending (red arrow) (+/+, N = 60; +/−, N = 50; −/−, N = 50). c–d Normal morphology and body length of shank3b +/+ , shank3b +/− , and shank3b −/− larvae at 3 dpf (c) and adults (6 mpf, male) (d) (N = 20 for each genotype). e–f Significantly enlarged brain size (e) but normal brain weight (f) in adult male shank3b −/− (6 mpf) compared to WT zebrafish (N = 30 for each genotype). *p < 0.05
