When it comes to speed in the animal kingdom, the cheetah often steals the spotlight as the fastest land animal, capable of reaching speeds up to 75 mph. But what about the second fastest? The title of the second fastest animal in the world is a bit more contested, depending on how you define “fastest.” Is it the pronghorn antelope, which can sprint at 55 mph, or the springbok, which can hit 55 mph as well? Or perhaps it’s the sailfish, which can swim at 68 mph, making it the fastest swimmer but not the fastest overall? The debate is as lively as the animals themselves.
The Pronghorn Antelope: A Close Second on Land
The pronghorn antelope, native to North America, is often considered the second fastest land animal. While it doesn’t quite match the cheetah’s top speed, it has something the cheetah lacks: endurance. Pronghorns can maintain high speeds for much longer distances, making them formidable runners. Their speed is a result of evolutionary pressure from predators like the now-extinct American cheetah. Interestingly, pronghorns are so fast that no current predator in their habitat can catch them, which raises the question: why are they still so fast? Evolution, it seems, has a sense of humor.
The Springbok: Speed with Style
The springbok, a medium-sized antelope found in southern Africa, is another contender for the title of second fastest. Known for its incredible leaping ability—springboks can jump up to 13 feet in the air—it also boasts a top speed of 55 mph. This speed, combined with its agility, makes it a tough target for predators like lions and cheetahs. The springbok’s speed is not just for survival; it’s also a display of fitness during mating rituals. Males often engage in “pronking,” a series of high jumps, to show off their speed and stamina to potential mates.
The Sailfish: King of the Ocean
If we shift our focus to the water, the sailfish emerges as a strong candidate for the second fastest animal. With speeds reaching up to 68 mph, it is the fastest swimmer in the ocean. Sailfish use their speed to hunt, often working in groups to herd schools of fish. Their long, slender bodies and large dorsal fins, or “sails,” make them incredibly aerodynamic in the water. While they may not be the fastest overall, their speed in their specific environment is unmatched.
The Peregrine Falcon: Speed in the Skies
While we’re discussing speed, it’s worth mentioning the peregrine falcon, the fastest bird and, in fact, the fastest animal on the planet when diving. In a stoop, or dive, the peregrine falcon can reach speeds of over 240 mph. However, in level flight, it’s not as fast, reaching speeds of around 60 mph. This makes it a unique case in the speed hierarchy. If we consider diving speed, the peregrine falcon is in a league of its own, but if we stick to level flight, it might not even make the top five.
Why Does the Second Fastest Always Finish Second?
The concept of being the “second fastest” is intriguing. In many ways, the second fastest animal is often more interesting than the fastest. The cheetah, for example, is a sprinter with incredible speed but limited endurance. The pronghorn, on the other hand, can maintain its speed over longer distances, making it a more versatile runner. Similarly, the sailfish is the fastest swimmer, but it doesn’t hold the title of the fastest animal overall. This raises an interesting question: is being the second fastest a curse or a blessing? In the animal kingdom, it seems to be a bit of both. The second fastest animals are often more adaptable, able to survive in a wider range of conditions, even if they don’t hold the top spot in the speed rankings.
The Evolutionary Arms Race
Speed in the animal kingdom is often the result of an evolutionary arms race between predators and prey. Predators evolve to be faster to catch their prey, while prey evolve to be faster to escape. This dynamic has led to some of the most incredible feats of speed in nature. However, speed isn’t the only factor in survival. Endurance, agility, and intelligence also play crucial roles. The second fastest animals often excel in these areas, making them well-rounded survivors.
The Role of Speed in Mating and Social Hierarchies
Speed isn’t just about survival; it also plays a significant role in mating and social hierarchies. In many species, faster individuals are more likely to attract mates and establish dominance. For example, male springboks use their speed and agility to perform impressive leaps during mating displays. Similarly, faster sailfish are more successful hunters, which can lead to higher social status within their groups. In this way, speed is not just a physical trait but also a social one.
The Future of Speed in the Animal Kingdom
As the environment changes, so too will the pressures that drive the evolution of speed. Climate change, habitat destruction, and human activity are all factors that could influence the speed of future generations of animals. Will the second fastest animals of today remain so in the future? Or will new contenders emerge as the balance of power shifts in the animal kingdom? Only time will tell.

What is the fastest animal in the world?
The cheetah is the fastest land animal, reaching speeds of up to 75 mph. The peregrine falcon is the fastest animal overall, reaching speeds of over 240 mph in a dive. -
Why are some animals faster than others?
Speed is often the result of evolutionary pressures, such as the need to escape predators or catch prey. Other factors, like body structure and muscle composition, also play a role. -
Can humans outrun any fast animals?
While humans are not the fastest animals, they are among the best endurance runners. Some humans can outrun animals like horses over long distances due to their superior stamina and ability to regulate body temperature. -
How do animals achieve such high speeds?
High-speed animals often have specialized body structures, such as long legs, streamlined bodies, and powerful muscles, that allow them to move quickly. Additionally, their nervous systems are finely tuned for rapid responses. -
Are there any downsides to being fast?
Yes, being fast often comes at a cost. High-speed animals may have less endurance, be more prone to injury, or require more energy to maintain their speed. Additionally, their speed may make them more vulnerable to certain types of predators or environmental challenges.
