About the roundscale spearfish
Tetrapturus georgii
The roundscale spearfish is an Istiophoridae species of marlin living in the epipelagic zone of the Atlantic Ocean. It has long been misidentified as white marlin but can be differentiated thanks to their scale shapes that gives its name. Not much is known about this species. It could reach a length of 160 cm and 21.5 kg and has no conservation status yet due to a lack of data.
