Animals that Start with X
X-Ray Tetra
The X-Ray Tetra, also known as Pristella maxillaris, is a small freshwater fish commonly found in the Amazon and Orinoco basins. It is a popular aquarium fish due to its unique transparent body, which allows for a clear view of its internal organs and skeletal structure.

Lastly, we have the Xenops, a bird found in Central and South America. This bird has a unique appearance, with a long, curved bill and a brownish-gray coloration. It is often seen climbing up and down tree trunks in search of insects to eat.
Xenopus Frogs
Xenopus frogs are highly aquatic frogs that are native to sub-Saharan Africa. They are commonly studied as model organisms for developmental biology due to their large eggs and embryos, which are easy to manipulate and observe.
Xenopus Frog
/ˈziːnəpəs frɑːɡ/
Xenopus frogs lay their eggs in water, and the eggs are fertilized externally. The eggs are about 1.5 mm in diameter and are surrounded by a jelly-like coating that protects them from predators and mechanical damage. The eggs hatch into tadpoles after a few days.
Xerus
Xerus, also known as African ground squirrels, are small, sociable rodents found in Africa. They are known for their bushy tails, which they use as a canopy to shade themselves from the sun. Xerus prefer to live in dry, open habitats such as savannas and deserts.
Xerus
/ˈzɪərəs/
These squirrels are social animals and live in groups consisting of females and their young. Males are solitary and only join the group during the mating season. Xerus are active during the day and spend most of their time foraging for food. They are omnivorous and feed on a variety of foods including insects, seeds, and nuts.
Xiphias
When we think of the letter X, one of the first animals that comes to mind is the Xiphias, also as known Swordfish. This large, elongated fish is characterized by its long, flat, pointed bill, which it uses to slash through schools of fish.
Swordfish are found in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and are highly migratory. They can grow up to 177 inches long and can weigh over 1,400 pounds.
Xiphias
/ˈzɪfiəs/
One interesting fact about Swordfish is that they lose all their teeth and scales by adulthood. Instead, they rely on their bill to catch prey, which includes fish, squid, and crustaceans.
