Integrative Zoology, EarlyView.We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

RETINOMOTOR RHYTHMS IN THE GOLDFISH, CARASSIUS AURATUS
The Biological Bulletin, 1967 1. The goldfish retina shows a persistent circadian rhythm. In constant darkness for three days, the cones continued to shift positions in synchrony with the diel cycle. The amplitude of the shift decreased after the first night. A maximally dark-adapted retina was obtained only on the first night.2. Individual fish showed considerable variation in the
