This has been observed in zebrafish. At night ...
The neural spines of the first four vertebrae fuse and compress, forming one of the major structures of the apparatus. [ 1 ] [ 2 ] Study of the embryology of the Weberian apparatus has since been conducted on various other ostariophysan species, the outcomes of which have resulted in various interpretations of the development (and thus the ...
