Hidden diversity in sardines: genetic and morphological evidence for cryptic species in the goldstripe sardinella, Sardinella gibbosa (Bleeker, 1849).

Cryptic species continue to be uncovered in many fish taxa, posing challenges for fisheries conservation and management. In Sardinella gibbosa, previous investigations revealed subtle intra-species variations, resulting in numerous synonyms and a controversial taxonomy for this sardine. Here, we tes...
