Hatching Period
The duration of this period is from 48 to 72hours
- Transitions from Long-Pec to Protruding-mouth
- In this period, primary organ systems develop and cartilage development begins
- Pectorial fins are now elongated with a flat blade but still developing
- Jaws and Gills are also developing along side the pectorial fins
- Olfactory placodes are now developed in the anterior of the eye
- Hair Cells have differentiated
- The mouth is wide open and protrudes anteriorly just beyond the eye
- The first visible bone in the zebrafish, the cleithrum, can be seen between the first two myotomes
- Subintestinal vein is also prominant ventrally to the gut tract formation
