Isurus oxyrinchus, commonly known as the shortfin mako shark, is a powerful predator distinguished by its streamlined body, pointed snout, and dark blue back. It is the fastest shark, capable of reaching speeds up to 45 mph. Found in temperate and tropical oceans, it plays a critical role in maintaining marine ecosystem balance.

The shortfin mako shark (Isurus oxyrinchus) is found in temperate and tropical oceans worldwide. Its geographical distribution includes the Atlantic Ocean, Pacific Ocean, Indian Ocean, and the Mediterranean Sea. It is commonly found along the eastern and western coasts of the Americas, from the Gulf of Maine to southern Brazil, and from California to Chile. In the Atlantic, it ranges from Norway to South Africa, including the Mediterranean and the Black Sea.

The shortfin mako shark inhabits offshore waters, typically in open ocean environments. It prefers water temperatures ranging from 16 to 22 degrees Celsius but can be found in waters as warm as 30 degrees Celsius. It is known to dive to depths of up to 500 meters but is most commonly found in the upper layers of the ocean, near the surface.

As a highly migratory species, the shortfin mako shark occupies a crucial role as an apex predator within its ecosystem. It preys on a variety of fish, including bony fish and other shark species, and occasionally marine mammals. Its speed and agility make it a highly effective hunter, and it plays a significant role in controlling the population of its prey species, thus maintaining the balance in its marine environment.
