The Longfin Mako Shark, Isurus paucus, is a rare and elusive species found in deep tropical and temperate waters. This shark is known for its slender body, long pectoral fins, and superb speed. It primarily feeds on bony fish and cephalopods, playing a crucial role as a top predator in the oceanic ecosystem.

Isurus paucus, commonly known as the Longfin Mako Shark, is found in tropical and warm-temperate waters worldwide. Its geographical distribution includes the Atlantic Ocean, from the northeastern United States and the Gulf of Mexico to Argentina, as well as the central and western Pacific Ocean, and the Indian Ocean. It is also found in the Mediterranean Sea.

The Longfin Mako Shark inhabits pelagic zones, often found in open ocean waters ranging from the surface to depths of 500 meters. It prefers warm-water regions with temperatures typically ranging from 16 to 22°C (61 to 72°F).

As a highly migratory species, Isurus paucus occupies an ecological niche as an apex predator in the pelagic ecosystem, preying on a variety of fish and cephalopods. It has adapted to a life in the open ocean with long pectoral fins that aid in stability and maneuverability in the water column.
