Do you know of any animals that start with X? Most of us don’t have an answer to that question off the top of our heads, but there are actually quite a few! 

In this blog post, we’ll explore fascinating creatures with one thing in common—their name starts with the letter X.

Read on to learn more about these unique and interesting animals that start with X!

1. Xerus

The Xerus is a small mammal that is native to the African continent. It is often referred to as a ground squirrel and is a member of the Sciuridae family, which also includes the prairie dog, chipmunks, and marmots.

The Xerus has a grizzled brown fur coat and distinctive black stripes on its face. It spends most of its time on the ground, digging burrows and foraging for food such as nuts and seeds.

The Xerus can be found in many areas throughout Africa, ranging from the grasslands and savannahs of the south to the deserts of the north.

Although it typically lives alone, it may form large colonies of up to several hundred individuals. The Xerus is an active animal, spending much of its time foraging for food and avoiding predators such as jackals and birds of prey.

This is the first on our list of animals that start with X!

2. Xantis

Xantis is the second on our list of animals that start with X and has quite a unique story. These animals were first discovered in the late 1990s in the rainforest of Central Africa.
