Hippocampus reidi and H. subelongatus examined in this study. A-E) H. reidi at 4 to 35 dpp. Ossification is first visible at 16 dpp and the skull is heavily ossified by 35 dpp. F-I) H. subelongatus specimens at 4 dpp and at 8 dpp showing ossification present by 4 dpp. High magnifications of the head are also shown. Scale bars are A), B) is 200 µm, and C-E) are 300 µm and in F-I) are 500 µm.
