Mako Shark: The Ocean's Fastest Shark

74 km/h Through the Water

A sport fisherman hooks something large in Pacific waters off California. His rod bends violently. Before he can react, a 3-meter shark launches entirely out of the water 9 meters high. It performs an aerial somersault, crashes back into the water, and attempts to swim away at speeds approaching 74 km/h.

This is a shortfin mako (Isurus oxyrinchus) — the fastest shark on Earth and one of the fastest fish in any ocean. It combines explosive speed with spectacular leaping abilities, making it the most athletic of all sharks.

The Animal

Mako sharks are streamlined, powerful predators.

Physical features:

• Length: 2.5-3.2 meters typical; up to 4.45 meters maximum
• Weight: 60-180 kg typical; up to 500+ kg
• Body shape: torpedo-streamlined
• Color: deep blue on top, white underneath
• Eyes: large (for targeting fast prey)
• Teeth: triangular, razor-sharp

Two species:

• Shortfin mako (I. oxyrinchus): faster, more common
• Longfin mako (I. paucus): larger, less common

Most references to "mako shark" refer to the shortfin species, which is the speed record holder.

The Speed Record

Mako sharks can reach extraordinary speeds.

Measured speeds:

• Burst speed: up to 74 km/h (46 mph)
• Cruising speed: 35 km/h
• Typical hunting: 50-65 km/h during pursuits

Among sharks:

• Mako shark: 74 km/h
• Great white shark: 56 km/h
• Blue shark: 43 km/h
• Bull shark: 40 km/h
• Most sharks: under 25 km/h

Among fish:

• Mako shark: 74 km/h
• Bluefin tuna: 70 km/h
• Swordfish: 90 km/h (very brief bursts)
• Sailfish: 110 km/h (claimed but not reliably measured)

The mako is among the top 3-5 fastest fish species, and by far the fastest shark.

Why So Fast?

Mako speed comes from biological innovations.

Warm-blooded advantage:

Mako sharks are among the few partially warm-blooded sharks. They maintain body temperature 10°C warmer than surrounding water through:

Rete mirabile:

• Counter-current heat exchanger
• Warm muscle blood passes near cold blood returning
• Heat transferred to returning blood
• Muscles stay warm, outgoing blood stays cool

Consequences:

• More powerful muscle contractions
• Faster acceleration
• Dramatic speed advantage
• Can operate in colder waters

Aerodynamics:

• Torpedo-shaped body minimizes drag
• Smooth dermal denticles (shark skin)
• Efficient tail shape
• Streamlined fin placement

Muscle composition:

• High proportion of red (aerobic) muscles
• Fast-twitch fibers in key areas
• Specific adaptations for sustained speed

Jumping Out of Water

Mako sharks are famous for spectacular leaps.

Height records:

• Typical jumps: 3-5 meters above surface
• High jumps: 9-12 meters documented
• Comparison: great whites rarely exceed 3 meters

Why they jump:

Hunting:

• Pursue fast prey that escapes to surface
• Break through waves to catch targets
• Sudden direction changes via splash

Defense:

• Startle predators
• Confuse pursuing animals
• Physical intimidation

Reproductive:

• Male displays to attract females
• Power demonstrations
• Show fitness

When hooked:

• Try to break line
• Jump into boats (famous danger)
• Escape attempts

Mechanics:

Jumping requires:

• Explosive tail thrust
• Warm-blooded power
• Streamlined body for maintaining direction
• Coordination to land safely

---

Hunting Behavior

Mako sharks are pelagic (open ocean) predators.

Prey:

• Primary: bluefin tuna, skipjack tuna
• Secondary: bonito, mackerel, squid
• Opportunistic: other fast fish
• Rare: seabirds, smaller sharks

Hunting strategy:

Unlike great whites (ambush from below) or bull sharks (murky water attacks), makos:

1. Pursue: chase prey in open water
2. Match speed: accelerate to catch targets
3. Strike: rapid attack with sharp teeth
4. Secure: hold prey with grip
5. Consume: eat while still moving

Tuna specialists:

Makos evolved to hunt tuna, which are:

• Extremely fast
• Open ocean species
• Difficult for slower predators to catch
• Perfect match for mako capabilities

Feeding efficiency:

Despite high-speed hunting:

• Success rate moderate (25-40%)
• Can't sustain long pursuits
• Energy-expensive hunting style
• Effective despite misses

Where They Live

Mako sharks inhabit warm open oceans.

Global range:

• Atlantic: most of ocean, tropical to temperate
• Pacific: Indo-Pacific, Eastern Pacific
• Indian Ocean: widespread
• Mediterranean: present year-round
• Temperature range: 16-24°C preferred

Habitat:

• Pelagic: open ocean preferred
• Surface waters: primarily top 150 meters
• Avoid: coastal shallow waters

Reproduction

Mako reproduction is slow.

Sexual maturity:

• Females: 18-20 years (late for sharks)
• Males: 6-8 years
• Late maturity: contributes to conservation concerns

Breeding:

• Mating season: summer
• Fertilization: internal
• Gestation: 15-18 months

Offspring:

• 4-25 pups per litter
• Born approximately 70 cm long
• Viviparous (live birth, no eggs)
• Pups independent immediately

Reproductive rate:

• Every 2-3 years
• Not annual
• Limited lifetime offspring
• Population recovery slow

Attacks on Humans

Mako sharks rarely attack humans.

Attack statistics:

• Total unprovoked attacks: ~9 historical
• Fatal attacks: 1
• Rate: much lower than great white or bull
• Context: mostly during fishing encounters

Why rare:

• Pelagic lifestyle (away from swimmers)
• Rarely encounter coastal humans
• Different hunting habitat
• Don't approach divers aggressively

When attacks occur:

• Catch-and-release fishing
• Boat encounters
• Rarely open water swimmers

Danger level:

Despite low attack rate, makos are dangerous because:

• Extremely powerful jaws
• Razor-sharp teeth
• Aggressive when threatened
• Can leap into boats
• Commercial fishers often injured

The Blue Streak

Mako sharks represent evolution pushing shark biology to the limits.

Where most sharks optimized for specific environments (reefs, coasts, rivers, deep sea), makos optimized for pure speed in open ocean. Their warm blood, streamlined body, and powerful muscles produce top speeds no other shark approaches.

This specialization comes with costs. They cannot match great whites in ambush hunting. They cannot live in shallow coastal waters like bull sharks. They cannot filter feed like whale sharks. They are purely pelagic speed specialists -- and extraordinarily good at that specific niche.

Every mako shark swimming today continues the evolutionary success of pelagic speed predation. They hunt tuna in open ocean. They migrate vast distances. They leap spectacularly when provoked. They represent the limits of how fast sharks can swim and how far they can jump.

Their populations are declining faster than they can recover. Without international conservation cooperation, makos could become significantly rarer in coming decades. The fastest shark in the ocean needs protection from the most dangerous predator in ocean history — humans.

For now, they're still out there, cruising through open ocean at 35 km/h, accelerating to 74 km/h when pursuing tuna, occasionally leaping 12 meters out of water in spectacular aerial displays. The ocean's sprinter continues doing what it does best.

Frequently Asked Questions

How fast is a mako shark?

Shortfin mako sharks (Isurus oxyrinchus) can reach burst speeds of 74 km/h (46 mph), making them the fastest sharks on Earth. Their typical cruising speed is 35 km/h. Measuring their top speed is difficult because they're fast and unpredictable, but multiple scientific methods have confirmed speeds over 70 km/h. For comparison: great whites max at 56 km/h, bluefin tuna reach 70 km/h, and most fish swim under 30 km/h. Their speed comes from specialized muscles that generate more power per unit mass than cold-blooded shark species. They have counter-current heat exchangers (rete mirabile) that keep their muscles 10°C warmer than surrounding water. This partial warm-bloodedness gives them dramatic acceleration advantages. Their streamlined body and powerful tail amplify the effect. They need this speed to catch tuna and bonito -- some of the fastest fish in the ocean. Without their speed, they couldn't compete for these agile prey species.

Are mako sharks dangerous?

Mako sharks are potentially dangerous but rarely attack humans. They have triangular razor-sharp teeth and are capable of causing serious injury. However, they prefer pelagic (open ocean) habitats and rarely encounter beachgoers or coastal swimmers. Over the past century, only about 9 unprovoked attacks have been attributed to mako sharks globally, with 1 fatality. Compared to bull sharks, tiger sharks, or great whites, they are far less likely to attack humans. Most documented mako attacks occurred during fishing -- when the shark was hooked or threatened. They have a reputation for being aggressive when cornered or threatened, and their speed and power make any encounter dangerous. Deep-sea fishermen targeting them face the most risk -- they famously leap out of the water during fights and attack boats. They are considered among the most dangerous sharks to catch on rod and reel because of their aggression, speed, and ability to jump into boats. For most people, mako sharks pose no realistic threat unless specifically encountered in open ocean fishing situations.

Why do mako sharks jump out of the water?

Mako sharks are famous for their spectacular jumps, reaching heights of 9-12 meters above the water surface -- one of the highest leaps of any shark. They jump primarily during hunting when pursuing fast prey at the surface, attempting escape from predators, or during reproductive displays. Their powerful tail muscles and warm-blooded metabolism provide the explosive energy needed for such jumps. When hooked by fishermen, they often leap in their attempts to break free, sometimes landing in boats. The jumps require tremendous power -- they must generate enough thrust to launch their 100-500 kg body completely out of water. Their streamlined body and specific fin design help them maintain control and direction even while airborne. Great white sharks also jump (breach) but generally not as dramatically. The combination of speed + jumping ability makes makos distinctive among sharks. Their spectacular aerial displays have made them particularly famous, featured extensively in wildlife documentaries and sport fishing footage.

Where do mako sharks live?

Mako sharks inhabit tropical and temperate open ocean waters worldwide, preferring pelagic (open ocean) environments rather than coastal areas. Their range includes the Atlantic, Pacific, and Indian Oceans in warm to cool temperate waters. Common regions include the Atlantic waters off North America and Europe, Pacific waters from California to Chile, Mediterranean Sea, and Southern Hemisphere waters around Australia, South Africa, and New Zealand. They typically stay in deeper waters (usually 0-150 meters) away from coastlines. They migrate seasonally, following prey fish movements across vast ocean distances. Tagged makos have been tracked traveling over 16,000 km annually. They show some fidelity to specific oceanic regions but roam widely. Unlike bull sharks (coastal) or great whites (mixed), makos are true pelagic sharks that spend most of their lives in open water. This means they rarely encounter divers, swimmers, or surfers. They are primarily fished in commercial pelagic fisheries targeting tuna, swordfish, and similar species.

How big are mako sharks?

Adult shortfin mako sharks reach 2.5-3.2 meters (8-10 feet) typically, with maximum size around 4 meters (13 feet). The largest verified specimen was 4.45 meters long. They weigh 60-180 kg typically, with large specimens reaching 500+ kg. They are medium-sized sharks -- smaller than great whites or whale sharks, larger than many coastal shark species. Longfin mako sharks (Isurus paucus) are slightly larger, reaching up to 4.4 meters. Females grow larger than males (typical for sharks). Their lifespan is estimated at 29-32 years in wild conditions. Sexual maturity for females occurs at around 18-20 years -- relatively late. They have a slow reproductive rate, with gestation lasting 15-18 months producing 4-25 pups per litter. Their rapid growth initially is dramatic -- young makos grow much faster than most shark species due to their active predatory lifestyle requiring substantial food. Their size combined with speed makes them effective predators of large, fast prey like tuna.
