Eggs, larvae and juveniles of Podothecus sachi kept at 5°C. (A) 2-cell stage, 20 hours after 
immersion in seawater. (B) Formation of optic lenses, auditory vesicles, Kupffer’s vesicle, 
and myomeres, 22 days after immersion in seawater. (C) Embryo almost in full circle, 42 
days after immersion in seawater. (D) Just before hatching, 92 days after immersion in 
seawater. (E) Newly hatched larva 7.0 mm in notochord length (NL), 92 days after immer- 
sion in seawater. (F) 7.4-mm-NL larva, 14 days after hatching. (G) 7.7-mm-NL larva, 28 
days after hatching. (H) Juvenile 8.7 mm in standard length (SL), 42 days after hatching. 
(I) Juvenile 15.6 mm in SL, 60 days after hatching. Dashed vertical line indicates the 
position of genital duct’s opening. 
parietal ridges with one spinule (Fig. 4F). The pecto- 
ral fins began to enlarge, and the larvae spent more 
time swimming near the surface than lying on the 
bottom. A 7.7-mm-NL specimen observed on the 28th 
day had 14 rays in its pectoral fins, melanophores 
on the ventral sides of the abdomen, and both jaws 
protruded slightly (Fig. 4G); four spines on preop- 
ercular and 2—4 spinules on each frontoparietal ridge 
were found. Another specimen measuring 8.3 mm NL 
on the 28th day was found to be in flexion; the larva
