Description

By 104 hpf, it is possible to distinguish the dorso-posterior aspect the ceratohyal (ch) from the ventral portion of the articulating interhyal (ih) by a slight decrease in fluorescence (*). The ventro-anterior aspect of the ceratohyal now projects further anteriorly than the dorso-anterior. The articulation with the basihyal (bh) dorsally and contralateral ceratohyal medially at the anterior midline is now clearly distinct. Branchiostegal ray 3 (bsr3) projects posteriorly from its articulation with the postero-lateral aspect of the ceratohyal.
