Proposal of a trophic relationship between Chaetognatha and Cnidaria based on Mitochondrial COI sequences ArchiMer
Da Mota Melo, Danielle Caroline; Costa Brandao, Manoela; De Albuquerque, Simone Maria; Neumann-leitão, Sigrid.
This is the first study in Brazil to propose a trophic relationship between Chaetognatha and Cnidaria based on molecular data (COI gene - DNA barcode). Cnidaria COI sequences were detected in tissue samples from two specimens of Flaccisagitta enflata collected in the surroundings of Fernando de Noronha archipelago, Tropical Western Atlantic. The methodology used followed all the requirements for a safe molecular manipulation, making the possibility of contamination unlikely. A search carried in BLAST showed that both sequences provided here presented a combination of highest query coverage and match identity with Nemopilema nomurai (Cnidaria: Scyphozoa), supporting the hypothesis that they belong to a species of jellyfish. Since gelatinous taxa are known...
