Discover the unique traits of shortfin and longfin makos, their incredible speed and hunting behavior, and their critical conservation status. From their streamlined physiology to their global migration patterns, we explore every facet of these apex predators.
Overview of Mako Shark Species
Mako sharks include two distinct species: the shortfin mako shark (Isurus oxyrinchus) and the longfin mako shark (I. paucus). These swift, active, and potentially dangerous sharks belong to the mackerel shark family, Lamnidae.
The shortfin mako shark inhabits all tropical and temperate seas worldwide, known for its remarkable speed and agility. This species is distinguished by its streamlined body, pointed snout, and crescent-shaped tail. Their body color ranges from blue-gray to deep blue dorsally and white ventrally. Adult shortfin mako sharks can grow up to about 4.5 meters (14.8 feet) in length and exceed 500 kg (1,100 pounds) in weight.
| Species | Geographic Range | Maximum Length (m) | Maximum Weight (kg) |
|---|---|---|---|
| Shortfin Mako (I. oxyrinchus) | Tropical and temperate seas | 4.5 | 500 |
| Longfin Mako (I. paucus) | Tropical seas | 3.8 | 170 |
The longfin mako shark, on the other hand, is scattered worldwide in tropical seas. This species also has an efficient and streamlined body but is known for its longer pectoral fins compared to the shortfin mako. The distinctive physical features contribute to their swift and active nature in deeper, warmer waters.
The shortfin mako is renowned as the fastest known shark, capable of reaching speeds up to 46 miles per hour in quick bursts. This incredible speed is attributed to their strong muscles, streamlined bodies, and specialized blood vessels that maintain higher body temperatures than the surrounding water, helping them stay warm and active.

The hunting strategy of mako sharks is characterized by their speed and agility. By utilizing their streamlined bodies and powerful tails (visit mako shark tail for more info), mako sharks can launch rapid attacks on their prey, exhibiting remarkable bursts of energy and precision.
Conservation Status
Understanding the conservation status of the mako shark species is essential to grasp the challenges these sharks face.
Threats to Mako Sharks
Shortfin mako sharks face numerous threats that have brought their populations to alarming levels. One of the most significant threats is bycatch. These sharks are often caught unintentionally in longline fishing operations targeting species like swordfish and yellowfin tuna. Despite not being the primary target, the high-quality fins and meat of mako sharks make them a valuable bycatch.
| Threat | Description |
|---|---|
| Bycatch | Unintentional capture in longline fishing targeting other species |
| Commercial Fishing | Targeted for their high-quality fins and meat |
| Habitat Loss | Increasing ocean pollution and habitat destruction |
Declining Populations and Bycatch
The decline in mako shark populations is a significant concern. The shortfin mako shark was recently reclassified from “Vulnerable” to “Endangered” due to rapidly declining numbers and the increased risk of extinction (NOAA Fisheries). This reclassification highlights the urgent need for increased conservation efforts.
These sharks are highly migratory, often traveling long distances every year. This migratory behavior exposes them to multiple fishing zones and various fishing methods, increasing the likelihood of being caught as bycatch. The combination of being sought after for their quality fins and meat, and their accidental capture, contributes significantly to their population decline.
To mitigate these impacts, increased awareness and stricter regulations are necessary. Conservation efforts must focus on reducing bycatch, protecting critical habitats, and enforcing sustainable fishing practices.
