Fastest Animals

Haliaeetus leucocephalus

The bald eagle is a large bird of prey and the national bird of the United States, typically found near large bodies of open water with an abundant fish supply, from Alaska and Canada down through the contiguous United States. The species was once endangered in the U.S. due to hunting, habitat loss, and the pesticide DDT, which thinned its eggshells and caused widespread breeding failures; after DDT was banned and decades of conservation effort, bald eagle populations recovered enough for the species to be removed from the U.S. endangered species list in 2007.

Acinonyx jubatus

The cheetah is the fastest land animal on Earth, built for explosive short sprints across the open grasslands and semi-desert of Africa, with a small, remnant population also surviving in Iran. Its speed comes at a genetic cost: cheetahs went through a severe population bottleneck thousands of years ago, leaving today's cheetahs with unusually low genetic diversity, which makes the species more vulnerable to disease on top of the threats it already faces from habitat loss and human-wildlife conflict.

Cathartes aura

The turkey vulture is a widespread scavenger found across the Americas, playing a critical ecological role by cleaning up carrion using one of the keenest senses of smell in the bird world.

Aepyceros melampus

The impala is a medium-sized antelope found across eastern and southern African savannas, famous for its explosive leaping ability when startled.

Panthera onca

The jaguar is the largest big cat in the Americas and the only living member of the genus Panthera found in the New World, prowling the rainforests of Central and South America.

Panthera leo

The lion is one of the world's most recognizable big cats, known as the 'king of the jungle' despite living mainly on open savanna, and is the only cat species that lives in large social groups called prides.

Thunnus albacares

The yellowfin tuna is a large, fast-swimming fish found in tropical and subtropical waters across the world's oceans, prized both as one of the ocean's most powerful predators and as one of the most commercially important fish species for human consumption. Its name comes from the bright yellow coloring of its dorsal and anal fins, which become especially long and dramatic in mature adults.

Panthera tigris tigris

The Bengal tiger is the most numerous tiger subspecies, with India alone holding the large majority of the world's wild tiger population, and it is the largest wild cat native to Asia's forests, mangroves, and grasslands. Smaller populations also survive in Bangladesh, Nepal, and Bhutan, including in the Sundarbans, a vast mangrove delta shared by India and Bangladesh where tigers are unusually strong swimmers and sometimes hunt aquatic prey. India launched Project Tiger in 1973 to protect the subspecies through a network of dedicated reserves, and the country's wild tiger population has grown substantially since, even as poaching for the illegal wildlife trade and habitat fragmentation remain serious ongoing threats.

Camelus dromedarius

The dromedary, or one-humped camel, is a large desert mammal domesticated thousands of years ago and superbly adapted to surviving extreme heat and long stretches without water.

Equus quagga

The plains zebra is the most common and widespread zebra species, roaming the grasslands of eastern and southern Africa in large, ever-shifting herds.

Canis lupus

The gray wolf is the largest wild member of the dog family, once ranging across nearly the entire Northern Hemisphere and living in tightly-coordinated family packs.

Panthera pardus orientalis

The Amur leopard is the rarest big cat in the world, a leopard subspecies adapted to the cold, snowy forests of the Russian Far East and northeastern China. Decades of poaching and habitat loss reduced the wild population to a critical low, though recent conservation efforts have helped numbers slowly recover from the brink.
