We’ve compiled an ultimate list of more than 130 animals that start with U! Our list uses only common names because scientific names are impossible to pronounce and probably not what you’re looking for.

We’ve also only included wild animals (no domestic animals or pet breeds). This list focuses on vertebrates (mammals, birds, reptiles, amphibians, & fish) but includes a couple invertebrate animals at the end, like the Urchin!

But first, how many animals beginning with u can you come up with? Go get some paper and a pen and try and make your own list first. We did the same (well, we had some help as we have a bunch of books over here but guess how many animals we got on our list?

How Many Animals That Start With U are on our list?

4 Reptiles

54 Fish
6 Invertebrates
= 137  Animals That Start With the Letter U!
