Why the Mako Shark is the Fastest Shark: An In-Depth Look at the "Ferrari of the Ocean"

When you think of sharks, you might imagine fierce predators gliding through the ocean with grace and power. While many sharks are formidable in their own right, there's one species that stands out for its speed and agility—the mako shark. Specifically, the shortfin mako shark (Isurus oxyrinchus) holds the title as the fastest shark in the ocean, and arguably, one of the fastest fish in the world.

But what makes the mako shark so fast? And what else makes it such an extraordinary creature? Let’s dive deep into the biology and behavior of the mako shark to understand why it’s considered the "Ferrari of the sea."

Speed and Power: The Mako’s Amazing Velocity

The shortfin mako shark is capable of reaching speeds of 60 mph (97 km/h), making it the fastest of all shark species. This incredible speed is a result of a combination of physical traits and specialized adaptations that enable the mako to move through the water with astonishing swiftness.

1. Streamlined Body Design

The mako shark’s body is perfectly adapted for high-speed swimming. Like an Olympic sprinter, the shark’s body is streamlined to reduce drag as it moves through the water. Its body is torpedo-shaped, allowing it to cut through the water with minimal resistance.

• Fin Structure: The shortfin mako has small, stiff pectoral fins that reduce drag, allowing for faster swimming. Its dorsal fin and tail are also designed for high efficiency. The tail (or caudal fin) is long and crescent-shaped, providing powerful propulsion and helping the shark reach high speeds in short bursts.
• Muscle Composition: The shortfin mako has a high proportion of red muscle fibers in its body, which are used for sustained, long-distance swimming. These muscles are particularly efficient at generating power over long periods. The mako also has white muscle fibers, which are suited for explosive bursts of speed—ideal for chasing prey or escaping danger.

2. Efficient Oxygen Use

Sharks, including the mako, have a unique circulatory system that allows for efficient oxygen transport to their muscles. This is key for maintaining their high-speed pursuits. Mako sharks, in particular, have a high concentration of myoglobin (a protein that stores oxygen in muscles) and hemoglobin (which carries oxygen in the blood). These adaptations allow the mako to sustain its high-speed bursts for longer than many other sharks, which rely on slower, more methodical swimming styles.

Additionally, the liver of a mako shark is particularly rich in oil, making it less dense and helping the shark maintain buoyancy in the water without exerting too much energy.

3. Tail Power and Asymmetrical Design

The mako shark’s tail (caudal fin) is one of the key factors that enable its speed. Its tail is heterocercal, meaning it is asymmetrical, with the top lobe being longer than the bottom lobe. This design allows the mako to generate strong upward thrusts, propelling it forward in the water.

• The tail is not only large but muscular, and with each powerful swing, the shark can generate incredible acceleration, launching it forward in seconds. The combination of a strong tail and a streamlined body helps the mako accelerate rapidly and reach top speeds.

4. Tapered Body Shape

Another factor contributing to the mako shark’s speed is its tapered body shape, which helps it slip through the water with minimal resistance. The shark’s skin is covered in tiny scales called denticles, which reduce drag and allow water to flow smoothly over its body. This helps the shark maintain its speed over long distances or when executing high-speed turns.

Behavior and Hunting Tactics

The mako shark’s speed is not just for show—it is essential to its hunting and survival strategies. The mako’s agility and ability to reach incredible speeds allow it to chase down fast-moving prey, such as tuna, swordfish, and other pelagic fish. The shark uses its speed to close the gap between itself and its prey in a matter of seconds, often striking with precision and swiftness.

• Ambush Predator: While the mako can swim at high speeds for long distances, it is also a skilled ambush predator. The shark will often approach its prey at a high rate of speed, using its burst of energy to strike at the fish in a surprise attack. This combination of speed and stealth makes the mako an efficient predator.
• Breaching Behavior: One of the most iconic behaviors of the mako shark is its ability to breach—leaping out of the water in spectacular, high-speed jumps. The mako often does this when pursuing prey or in response to environmental stimuli, such as changes in water pressure or the presence of other sharks. This breaching behavior is not only dramatic but may also serve to disorient prey or shake off parasites.

Habitat and Distribution

The shortfin mako shark is found in temperate and tropical waters around the world, often in deep oceanic regions but occasionally venturing closer to the coast. Mako sharks are migratory, traveling vast distances in search of food and optimal water temperatures. This wide distribution means that makos are often found in areas where fast-moving prey, like tuna and swordfish, are abundant.

Lifespan and Reproduction

The shortfin mako shark has a relatively long lifespan for a shark, living to around 30 years. However, they mature slowly and reach reproductive age later in life, around 8-10 years old. The shark’s reproductive strategy, like many others, involves live birth (ovoviviparity), with females giving birth to litters of 4-18 pups. Despite their impressive speed and agility, mako sharks face threats from overfishing and habitat degradation, which have led to declining populations in certain regions.

Conservation and Threats

Although the mako shark is an apex predator and one of the fastest creatures in the ocean, it faces threats from overfishing, bycatch, and habitat loss. Both shortfin and longfin makos have been targeted for their meat and fins, and their populations have dwindled in certain areas. The International Union for Conservation of Nature (IUCN) has classified the shortfin mako shark as "vulnerable", highlighting the urgent need for conservation efforts to protect this remarkable species.

Conclusion

The shortfin mako shark is the Ferrari of the ocean for good reason. Its speed, efficiency, and elegance in the water are the result of millions of years of evolutionary refinement. The mako's streamlined body, powerful tail, and specialized muscle structure make it not just the fastest shark but one of the most efficient predators in the ocean. Its ability to reach speeds of up to 60 mph gives it an edge in the competitive world of apex predators, allowing it to outpace prey and rivals alike.

Despite its incredible prowess, the mako shark’s future is threatened by human activity, reminding us that even the fastest creatures on Earth are vulnerable and in need of protection. If we want to continue marveling at the majesty of the mako shark, it’s crucial that we take steps to safeguard its future and preserve the delicate balance of marine ecosystems.
