Animals That Start With X: A List of All the Animals Beginning with X

What are some animals that start with X? How many can you come up with? Think hard! 

We have come up with a list of English common names of vertebrate animals that start with x. And includes the Xeme. What’s a Xeme? The Xeme is a Sabine’s gull, also known as the fork-tailed gull. But that’s just the beginning of all the animals that start with x that we found.

animals that start with x, the xeme
One of my favorite animals that start with x. The Xeme!

Fake Animals Starting With X That I Found in Other Lists (Like Xantis and Xanthareel)

When I researched the names from other lists, I found a lot of false information being repeated over and over. For example, you will often see the Xantis yak appear on lists of animals beginning with x. There is not a single authoritative site that refers to any yak species as a Xantis. However, you will find dozens of animal alphabets using it! Guess what! It is neither a common name, nor a scientific name for any type of yak. Where did it come from? So far I have no idea.

A similar problem is Xanthareel, which seems to show up over and over in lists of animals that start with x and is vaguely defined as “a yellow eel formerly used in medicinal foods”. But again, there is no authoritative reference to the word anywhere as an actual name of an animal. But if it was, this would definitely be my favorite animal that starts with x. It is just another made-up word perpetuated by a single site and repeated by hundreds of others.

It would seem that people are so desperate to find an animal that starts with x, they’ll repeat anything they read. Which is why I decided to create this authoritative list of animals that start with x!

Xanthareel, not a real animals that start with x
Sorry guys, there’s no such thing as a Xanthareel. Look below to find some real animals that start with x!

(A Quick Note About Scientific Names of Animals That Start With X)

Usually, when I compile a list of animals that start with a certain letter (like animals that start with n, animals that start with u, and animals that start with e) I only use English common names.  I don’t use scientific names because that’s not really what people are looking for and it usually adds many thousands of names to a list. However, for animals that start with x, I had to dig a little deeper.

For each animal group below I start with an alphabetical list of common names in bold, and then an alphabetical list of scientific names of animals that start with x in bold italics. For any genus with multiple species in it I include only the genus name (plus the number of species in parenthesis).

If you’re curious what all the species in that genus are, try searching the genus name in Wikipedia or on the IUCN Redlist. I’ve also included a few higher classifications like the superorder Xenarthra (that includes anteaters, sloths, and armadillos). Any genus that has only one species in it, I list the full scientific name and the common name if there is one. At the end is a bonus list of dinosaurs that start with x and a couple other prehistoric animals that start with x!

If you want more information about any of these animals that start with x, you can highlight a name in the list and then right click it in your browser. Choose “Search with Google” and check the results. Some of my favorite information sources are the IUCN Redlist, Arkive, Fishbase, the Cornell Lab of Ornithology, Encyclopedia of Life, & One Zoom.

  2. Xanthippe’s Shrew (a shrew in Kenya & Tanzania)
