High similarity of 16S rRNAs between two jellyfishes, Aurelia aurita and Dactylometra quinquecirrha

Abstract

To obtain genetic information from two jellyfishes Aurelia aurita and Dactylometra quinquecirrha, we amplified 16S rRNAs and sequenced 503 bp. After comparison of the two species, we found 4 bp of differences between both jellyfish. This result shows that these jellyfishes do not have a big difference in nucleotide sequences, even though they are different species. This also indicates that we need to get more sequence information to identify the species, especially in early developmental stages.
