Tiger Camouflage

By | March 9th, 2016|Tags: |Comments Off on Tiger Camouflage

Lots of animals have camouflage, colors and textures that help them blend into their environments– think of dull brown ducks that blend into the ground where they nest, or green katydid insects that blend into the leaves. But what about tigers?

At first glance, their bright orange coats don’t seem like they’d be good for blending into anything!

However, their orange coloring and black stripes actually provide excellent camouflage in the grassy forests where they live. Their stripes blend in with the tall grasses that

they crouch behind, and their orange color actually provides pretty good cover when they’re hunting at dusk when the sun is setting. Check it out!

What Even Is an Old World Monkey?

By | March 2nd, 2016|Comments Off on What Even Is an Old World Monkey?

The latest issue of Zoobooks features Old World Monkeys. But what exactly are they?

First of all, let’s go over the difference between monkeys and apes. Chimps, gorillas, and humans are all examples of apes; langurs and tamarins are types of monkeys. What’s the difference? One good rule of thumb is that most monkeys have tails, while apes don’t. Apes are often larger than monkeys, too. In general, apes rely more on their sense of sight, while monkeys rely more on smell, and apes tend to have broader, shorter noses.

When it comes to Old World Monkeys found in Africa and Asia and the New World Monkeys in the Americas, one difference is in their tails—generally speaking, Old World Monkeys don’t have prehensile tails, but New World Monkeys do. There are also differences in the monkeys’ teeth, and Old World Monkeys have nostrils that face sideways (they face downward in New World Monkeys). See if you can spot some of these differences the next time you see monkeys at the zoo!

Di-no's: These Aren't Dinosaurs

By | February 17th, 2016|Comments Off on Di-no's: These Aren't Dinosaurs

We refer to the Triassic, Jurassic, and Cretaceous periods as “the Age of Dinosaurs,” but they weren’t the only animals alive then.

Dimetrodons look like dinosaurs, but they’re actually more closely related to humans than to T. rex. They lived before the dinosaurs did, and they’re part of the group that branched off and eventually became mammals. We can tell by looking at the openings in their skulls– they have an extra hole by their ears that dinosaurs don’t have.

Pterosaurs, the flying reptiles, lived at the same time as the dinosaurs, but they’re actually only distantly related to each other. One way that we can tell is by looking at their leg bones– dinosaurs had different features on their limbs to help make them stronger.

Mosasaurs and other swimming reptiles aren’t dinosaurs either. They’re on a different branch of the family tree, more closely related to crocodiles and Komodo dragons than to dinosaurs. Their limbs sprawled out to the sides, while dinosaurs carried their legs directly beneath them. (Think about the difference between how a lizard’s legs are splayed out, but a bird’s legs are carried straight beneath their bodies.)

When paleontologists determine where an animal falls on the tree of life, they look at lots of specific little traits, like the structure of specific bones, to see just where they fit. These differences, like holes in the skull and the shape of the leg bones, might not seem important to the untrained eye, but they’re key for scientists to determine how animals are related to each other.

Brand-new Dinosaur

By | January 27th, 2016|Comments Off on Brand-new Dinosaur

Have you heard about the new giant dinosaur at the American Museum of Natural History? Fossils from a new species of titanosaur (so new that it hasn’t been named) are on display, along with a 122-foot-long replica, called a cast, showing what the entire skeleton would look like. For reference, 122 feet is about the length of three city buses laid end-to-end. You can learn about it here.

There are amazing new discoveries happening every day in paleontology, and with our new book series about dinosaurs, we’ll share all the latest facts and stories that will get kids hooked on science and reading. We can’t make it happen without your help, though—visit our Kickstarter website to learn how you can make a difference!

Old Dinosaurs, New Name

By | January 13th, 2016|Comments Off on Old Dinosaurs, New Name

Dinosaurios_Park,_Oviraptor

Did you ever get a nickname that stuck when you didn’t really think it fit? Imagine how Oviraptors would feel. Their fossils were found around dinosaur nests, so paleontologists thought that they were stealing the eggs and gave them a name that means “egg thief.” Well, it turns out those Oviraptors had a good reason to be at those nests– they were taking care of their own eggs!

One of the great things about science is that it changes every day. That’s why we’re creating a brand-new series of books to teach kids about these amazing animals. Any help that you can give us is very much appreciated– and you can get some awesome dinosaur toys and prizes for being a part of our start-up!

Dinosaurs' New Look

By | January 6th, 2016|Comments Off on Dinosaurs' New Look

Sorry, Jurassic Park, you’re showing your age.

When the first Jurassic Park movie was made in 1993, the jury was still out on whether or not dinosaurs had feathers. Today, there’s no doubt in scientists’ minds—lots of dinosaurs, including T. rex and Velociraptor, had feathers. You can see some on this fossil—the dark brown fringe along the animal’s spine is made of feathers!

Early feathered dinosaurs didn’t use their feathers for flight, though—instead, they were probably all for show. Feathers could make the dinosaurs look bigger to intimidate predators, and they could be used to attract mates, just like peacock feathers today.

The idea of lizard-like dinosaurs has stuck in people’s minds, though, in part due to the scaly-skinned predators in movies like Jurassic Park. Some people think that it “ruins” dinosaurs to picture them with feathers, saying that they wouldn’t be scary any more. To which we say, really? You’re not scared of this?

Deinonychus_im_NHM_Wien

In the new book about dinosaurs that we’re working on, we’ll be sharing dinosaurs with a whole new generation, giving kids (and their parents) the most cutting-edge scientific information about these amazing animals. Please help us make it happen!

Tiny Readers, Tiny Owls

By | December 23rd, 2015|Comments Off on Tiny Readers, Tiny Owls

The owls in our latest issue of Zoobies got us thinking- those books are geared toward our smallest readers, so what better time to talk about the world’s smallest owls? Burrowing owls are just a little bit bigger than a robin. True to their name, they live in underground nests, including old prairie dog burrows. They’re some of the only owls that are active during the day, but they still do most of their hunting at night. You can spot them in the western United States during the summer, but this time of year, they’re in Central and South America.

The World’s Smallest Frog

By | December 9th, 2015|Comments Off on The World’s Smallest Frog

Paratype_of_Paedophryne_amauensis_(LSUMZ_95004) (1).pngAs you might remember from the latest issue of Zootles, there are all kinds of frogs in the world. One of our favorites is this newly discovered frog from Papua New Guinea (an island nation just north of Australia). Scientists discovered them living in dead leaves on the jungle floor in 2012. The tiny frogs make sounds like insects, and the scientists who heard their calls tracked them down to see what was making the noise—they never expected to stumble across the world’s smallest frogs!

At 0.27 inches long, they’re one of the world’s smallest vertebrates, or animals with backbones. This one fits on a dime with plenty of room to spare! Can you imagine discovering a new species? Where would you look?

St. Louis Zoo Cheetahs

By | December 2nd, 2015|Tags: |Comments Off on St. Louis Zoo Cheetahs

Cheetah Cheetah at Whipsnade Zoo

The St. Louis Zoo is home to some amazing animals, including cheetahs. Even if you can’t make it out to the zoo to visit them, you can still learn all about these amazing animals on their website. For instance, have you ever noticed the long black “teardrops” under cheetahs’ eyes? On their site, you can learn about how these stripes may help cheetahs see their prey better by reducing glare, like the eye black that baseball players wear. Is there anything else you’ve ever wondered about these animals? There’s a good chance that you can find the answers with a little help from the St. Louis Zoo!

Lightning Fast

By | November 25th, 2015|3 Comments

Quickwhat’s a fact you know about cheetahs? Chances are, the first thing that came to your mind was their speed. It’s a reputation they’ve earnedthey’re the fastest land animals, reaching up to 70 miles per hour. But did you know that they can go from standing still to running at 45 miles per hour in two seconds? That’s faster than most race cars can accelerate!

Cheetahs’ long legs and flexible spines help them move at high speeds, and their muscular tails help them balance.

Why do cheetahs need to be so fast? Rather than stealthily sneaking up on their prey in close quarters and relying on brute strength, cheetahs use their speed to hunt. They live on open, grassy savannahs, where they spot their favorite prey, fast-moving animals like gazelles, from a distance. When food is scarce, though, cheetahs eat small animals and even birds’ eggs and fruit!

Fun Facts and Crafts at the Shedd Aquarium

By | November 12th, 2015|Tags: |Comments Off on Fun Facts and Crafts at the Shedd Aquarium

Some bad news for all the kids out there who love dolphins, whales, and sharks—you probably can’t get one as a pet. But, thanks to the Shedd Aquarium’s fun crafts, you can decorate your room with them! Their website has all kind of fun sea creature-related activities for families to enjoy, from baby beluga origami to paper crowns decorated with sharks. You can also spend some time on the Shedd’s website to learn more about your favorite animals. For instance, did you know that dolphin milk has as much fat in it as half and half that we put in our coffee? That’s so that the baby dolphins can build up a layer of blubber to keep them warm in the cold water. There’s a lot to explore on the Shedd’s website—have fun!

Frozen Frogs

By | November 4th, 2015|Tags: , |Comments Off on Frozen Frogs

Rana_sphenocephalaIt’s starting to get chilly outside, and while some animals have thick layers of fur to keep them warm, other animals, like the frogs featured in the latest issue of Zootles, need to find other ways to stay warm. So how do cold-blooded, thin-skinned frogs keep warm in the winter?
Like many other animals, frogs slow down their bodies and hibernate during the winter. Frogs that spend most of the time in the water nestle into the mud at the bottom of their pond.They don’t bury themselves completely, though– they still need to be able to access the oxygen-rich water. Meanwhile, land-dwelling frogs burrow into the ground beneath the frost line. Some of them even have an “anti-freeze” substance in their bodies that prevents their organs from being damaged. Come spring, their bodies thaw, and they return to their normal, active lives.
