Marlins are represented by somewhere around 10 species spread throughout two genera: Istiophorus and Makaira. These species are further more differentiated into quite a few subspecies. The exact classification and range of species/subspecies are subject matter to ongoing scientific debate as a result of marlins’ vast distribution and morphological variations. https://costaricafishingexperts.com/wp-content/uploads/2016/09/LosSuenoFishingMarlin.jpg
