Marine fish biodiversity have been addressed the tremendous species diversity especially on tropical and subtropical regions. The species identification of marine fishes would be
very difficult for the different degree of larval stages for their own developmental process for surviving in the marine habitats due to lacking any further studies for developmental metamorphosis for most of marine fish species. Marine larval fish identification would be a very difficult task among huge species diversity of teloest fishes if the research is merely based on limited morphological observation of field sampling larval fish specimens
