In adult D. rerio, the center of the mesethmoid remains cartilaginous (Cubbage & Mabee, 1996). The mesethmoid meets the supraethmoid dorsally, the lateral ethmoids posterolaterally, and the vomer and parasphenoid ventrally in synostoses. Anterolaterally the mesethmoid meets the preethmoids in synchondroses. | ||
