How can morphology and DNA be used to identify different shark species now and in the future?

Generally any use of DNA can identify almost any species in the future or past. People who study creatures keep records of DNA that are stored within the Shark. If we amplify a standard DNA barcoding gene (COX-I) sequences (658 bp) of a specimen/animal species of which no sequence/reference data is available on DNA information data bases, e.g., gene banks, NCBI etc. If blast/comparison with other related species give about 96, 97% similarity, then how will we identify the species in this way. In this case, are we totally dependent on traditional taxonomy to work out the species identification or some other ways are there?
