| Research Abstract |
This study aims to investigate (i) mechanisms of different lifespans between polyp and medusa stages of a jellyfish, (ii) age estimation of coral polyps and colonies, (iii) establishment of symbiosis with zooxanthellae in coral larvae. Somatic tissues of a coral and a jellyfish exhibited telomerase activity. We applied the single telomere length assay (STELA) developed for humans to cnidarians. Our results suggest the possibility to estimate coral's age based on telomere length. Coral larvae can acquire different genotypes of zooxanthellae indicating less specificity compared to adult.
