With four kids, two dogs, a cat, and a bearded dragon, I often feel like I’m surrounded by animals! Animals are a big hit in our house. My kids get their love of animal facts from their dad. He always read them books about unusual animals as bedtime stories when they were little.

Now that everyone is a little older, I’ve found that my kids teach me about unusual animals, which I love! They’ll hear about a new animal from a YouTube video and then search the library for books about it. 

These moments are my favorite. With young kids up to teens in my family, it can be difficult to find ways for everyone to connect. Animals are a topic we all agree on! My big kids love teaching my little kids new things, like where Umbrellabirds live (the rainforest). 

Are you ready to learn new animal facts with your kids? Start now with our list of Common Animals that Start With the Letter U!

Common Animals that Start With U

Ready to get your adventure underway? Start with these fun facts about common animals that start with the letter U!

Urchin

Like Olaf, the loveable snowman, urchins don’t have skills…or bones. Instead, they have a hard outer shell of calcium to protect their tender bodies. Sticking out of their shells are long spikes, which would scare off anything brave enough to come near them. Their protective spikes must be doing something right because urchins can live to be 200 years old!

Umbrellabird

Umbrellabirds are easily identified by their amazing hairdos! They look like a bird version of Elvis Presley, with a dark black fringe of feathers that drapes over their beaks. Unlike Elvis’ graceful moves, umbrellabirds are clumsy fliers. To avoid having to fly away from predators, like hawks and monkeys, umbrellabirds carefully select their home. They share trees with woodpeckers and other birds and will hop from tree to tree to search for food.

Utah Prairie Dog

These tough little animals aren’t dogs at all! Utah Prairie Dogs are actually light brown rodents that are closely related to squirrels. They got their name from how they speak in short barks to each other; prairie dogs have an incredible range of sounds to communicate. They can even describe colors and shapes with their barks and squeaks! Prairie Dogs lived in little colonies, called towns, all over the United States. Unfortunately, human towns have threatened their homes, and prairie dogs are now an endangered species. 

Unau (Two-Toed Sloth)

The slow-moving Unau is a type of sloth. Everything about sloths is slow, from their movements to their digestive systems. Did you know that it can take an unau a whole month to digest a single leaf? Because Unau are slow-moving, algae and fungi can grow in their fur. What’s remarkable about this is that the algae that grow in sloth fur can fight against cancer! Wouldn’t it be amazing if these mammals held the key to curing one of humanity’s deadliest diseases?

Zoo Animals That Start With The Letter U

Unicornfish

The Unicornfish has a large horn that extends off of the front of the fish’s face, much like a long nose. Unicornfish love living in brightly colored reefs and can even brighten their scales to match their home! 

Uganda Clawed Frog

The Uganda Clawed Frog is another animal on our list that could benefit medical research. In fact, it was the first vertebrate to be cloned by scientists! Because the Uganda Clawed Frog has special skin that produces antibiotics to protect it from infection, the frog heals incredibly fast!

Uromastyx

These spiny-tailed lizards were named by the Ancient Greeks for their “tail whips.” When the Uromastyx feels threatened, it will use its mace-like tail to hit a predator and hiss. Hopefully, this scares the threat off!
