How many animals can you name starting with the letter X? It’s not apparent, like ‘A’ for antelope and ‘C’ for cat. Still, the world teems with fantastic creatures whose names begin with this little-known letter. 

Here are these fascinating animals, their habitat, distinguishing features, and why they are essential. Explore the incredible array of animals whose names begin with ‘X.’

Xerus

Xerus, also called the African ground squirrel, is a genus of highly social mammals that occurs in open grasslands and rocky African areas. They are bushy-tailed and have cheek pouches for storing food. 

They are adaptable to arid environments and live burrowed into the ground. Their incredible social nature sets them apart.

Fun Fact: Xerus squirrels are excellent foragers who can live for long periods without water, depending on the moisture in the food they consume.

Xenops

Xenops are small rainforest birds of Central and South America. These nimble cinnamon-colored creatures with upturned bills may be heard or seen chipping away at tree bark to find hidden insects.

Xantus Hummingbird

The Xantus hummingbird, named after Hungarian naturalist John Xantus, is native to Baja, California. It is a mid-sized marvel in the hummingbird family, and its vibrant green body and striking white eye stripe make it stand out. These birds are known for their loud metallic calls, essential to pollination.

Xeme

The Xeme is another term for the Sabine’s Gull, an Arctic seabird marked by forked tails and migratory heroics. 

These birds can be found near Siberia, Europe, and North America, and many will follow whales and seals to scavenge food.

Xiphias

Xiphias are commonly known as swordfish. They are famed for their speed and the equally famed long, flat bill. They can swim, occasionally reaching 60 miles per hour.

Xenotarsosaurus

Xenotarsosaurus was a carnivorous bipedal dinosaur from Argentina in the Late Cretaceous. Despite its name, its fossil records remain under debate.

Xanthippe’s Shrew

This small mammal with a broad muzzle lives in dry savannas and shrublands in Kenya and southwards in Tanzania. 

Like all shrews, Xanthippe’s shrew is a part of the order Eulipotyphla, whose members have a high metabolism.

Xoloitzcuintli

Appropriately known as the Mexican Hairless Dog or simply Xolo, this ancient breed has served as man’s loyal companion for more than 3,000 years. 

According to National Geographic, the Aztecs and Toltecs revered Xolos, who were thought to have mystical powers, guide souls to the afterlife, and so on. Typically, Xolos are unique in appearance for a dog and look particularly elegant and athletic.

Xenarthra

Xenarthrans are known to live at low metabolisms and move slowly. They are found mainly in Central and South America. 

Did You Know: They can eat up to 30,000 ants daily and thus provide natural pest control!

Xinjiang Ground Jay

Its name says it all—you’ll only see the rare Xinjiang Ground Jay, also called Biddulph’s Ground Jay, in the highly arid habitats of China. 

This bird prefers running and jumping to being airborne, employing its robust beak to dig out food from the ground.

Xenopus

Xenopus species, African clawed frogs, have smooth, slippery skin and live entirely in water. Because of their unique egg development, they are widely used in scientific research and have made key contributions to genetics and developmental biology.

Xantusia

Southern California’s Eastern Sierra and the San Gabriel Mountains are the homes of Xantusia, or night lizards, small reptiles. A secretive animal with granular textured skin, they clothe themselves well for camouflage.

Xenopeltis

There’s a dazzler of Southeast Asia: the sunbeam snake or Xenopeltis. When exposed to light, its scales reflect an iridescent rainbow of colors.

Xantus’ Leaf-Toed Gecko

This small reptile is found in Mexico. When held, it squeaks and can shed its fragile tail in defense. This is one of the unique ways animals enhance their self-defense.

X-Ray Tetra

The X-ray tetra is popular among aquarium enthusiasts for its almost see-through, translucent body. 

This smaller freshwater fish is naturally found in the Amazon River’s coastal waters and is excellent at adapting to changing water conditions.

Xestus Sabretooth Blenny

The Xestus sabretooth blenny is a fish with comb-like teeth and bright, camouflage-suitable colors that lives among coral reefs in the Indian and Pacific Oceans.

Xenoceratops

Xenoceratops was a horned herbivorous dinosaur that roamed present-day Canada during the Late Cretaceous.

Xenacanthus

This freshwater shark, named Xenacanthus, had a long, eel-like body and lived over 200 million years ago during the Triassic period.

Xiphosura

Xiphosura (horseshoe crabs) are wonderful marine arthropods, often confused with the crustaceans. They are also one of the remaining groups that evolved over 300 million years ago.

Through this wildly unique list, we can explore how even the scarcest letter in the English alphabet can characterize the stunning variety of these ecosystems. From mammals and reptiles to birds and even extinct creatures, the diversity of ‘X’ animals reminds us of the endless curiosities of the natural world.
