Overview

The Shortfin Mako is a large, fast-swimming shark in the family Lamnidae, related to the Great White Shark, and widely regarded as the fastest shark species in the ocean. It is found throughout tropical and temperate waters worldwide, typically well offshore in open ocean habitat. Makos are partially warm-blooded (regionally endothermic), allowing them to maintain muscle and organ temperatures above the surrounding water, which supports their exceptional speed and endurance. As apex predators, they play a critical role in regulating populations of fast pelagic fish and squid. Mako Sharks are a highly migratory species and are considered vulnerable due to slow reproduction and their tendency to travel through international waters.

How to identify it

  • Body: streamlined, torpedo-shaped, built for sustained high-speed swimming
  • Color: vivid metallic blue to purple-blue back, sharply demarcated bright white underside
  • Snout: long, pointed, and conical
  • Tail: crescent-shaped (lunate) caudal fin with strong lateral keels on the tail base
  • Size: typically 2.5-3.5 m
  • Look-alikes: Porbeagle Shark has a stockier body, shorter snout, and a white patch on the trailing edge of the dorsal fin, absent in Mako Sharks

Habitat & range

Shortfin Mako Sharks inhabit tropical and warm temperate waters across the globe, typically in the open ocean far from shore, though they occasionally approach continental shelves. They are found from the surface down to several hundred meters, favoring water temperatures generally above 16°C. As highly migratory animals, they undertake extensive movements across entire ocean basins, tracking prey and seasonal temperature changes. Their partial warm-bloodedness allows them to tolerate a broader range of temperatures than most sharks, giving them access to both warm surface waters and cooler deeper layers during dives.

Behavior & ecology

Mako Sharks are solitary, fast-swimming predators capable of short bursts of extremely high speed, allowing them to chase down fast prey such as tuna, mackerel, and squid. They are known for spectacular leaps out of the water, a behavior linked to hunting and evading capture. As regionally endothermic animals, they can keep their muscles warmer than the surrounding water, boosting swimming performance. Reproduction is ovoviviparous, with developing embryos practicing oophagy, feeding on unfertilized eggs in the uterus, resulting in small litters of well-developed pups. Their role as top predators helps regulate populations of fast-moving pelagic fish.

Frequently asked questions

What makes the Mako Shark the fastest shark?

Its streamlined torpedo body, crescent-shaped tail, and partially warm-blooded physiology allow bursts of extremely high swimming speed.

How can you tell a Mako Shark from a Porbeagle?

Mako Sharks have a more slender body, longer pointed snout, and lack the white trailing edge on the dorsal fin seen in Porbeagles.

Where do Mako Sharks live?

They roam open tropical and temperate oceans worldwide, generally staying well offshore in warm surface waters.
