Abstract Fourteen juvenile scalloped hammerhead sharks ( Sphyrna lewini ; SHS) were captured between November and December 2014 in the Rewa Delta in Fiji, and assessed for intestinal microflora characterisation using 16S rRNA amplicon sequencing by Illumina Miseq. The microbial population revealed a fluctuating dominance between the Enterobacteriaceae and Vibrionaceae families, namely Citrobacter and Photobacterium spp. Other related marine operational taxonomic units were closely related to Afipia felis , Chloroflexus aggregans , Psychrobacter oceani , Pontibacter actiniarum and Shigella sonnei . Two sharks had distinctive profiles that were dominated by known pathogens, namely Aeromonas salmonicida and Klebsiella pneumonia . The presence of a Methanosaeta species, and of Shigella and Psychrobacter , would suggest sewage contamination because of a spill that occurred on the 6 th of December 2014. This study successfully establishes a baseline for future research.
