Types of Marlin
The Atlantic blue marlin (Makaira nigricans) is a species of marlin endemic to the Atlantic Ocean. It is closely related to, and usually considered conspecific with, the Indo-Pacific blue marlin, then simply called blue marlin. Some authorities still consider both species distinct.
The black marlin (Istiompax indica) is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans. With a maximum published length of 4.65 m (15.3 ft) and weight of 750 kg (1,650 lb), it is one of the largest marlins and also one of the largest bony fish.
The Mediterranean spearfish (Tetrapturus belone) is a species of marlin native to the Mediterranean Sea where it is particularly common around Italy, although there is a probable record of one caught off Madeira. It is an open-water fish, being found within 200 metres (660 ft) of the surface.
The roundscale spearfish (Tetrapturus georgii) is a species of marlin native to the eastern Atlantic Ocean from Portugal to Madeira, the Canary Islands to northern Africa and the western Mediterranean Sea to Sicily. It is suspected that it may be more widespread. It is believed to inhabit open waters.
The Marlin's dorsal fin is actually one connected fin whereas the Sailfish dorsal fin is a series of fins connected together a bit like feathers (they are called pleats). When Marlin Fishing Miami, a smaller dorsal fin is certainly an easy thing to spot.
The shortbill spearfish (Tetrapturus angustirostris) is a species of marlin native to the Indian and Pacific Oceans, with occasional records from the Atlantic Ocean. This species occurs in open waters not far from the surface.
Striped marlin, along with white marlin and the three species of spearfish, make up a fourth genus (Kajikia). Interestingly, striped marlin can also tolerate much cooler water temperatures than blue, white or black marlin, which means they can push deeper into the corners of the Pacific than other billfish species.
White marlin (Kajikia albida), also known as Atlantic white marlin, marlin, skilligalee, is a species of billfish that lives in the epipelagic zone of the tropical and subtropical Atlantic Ocean.
