Algunas veces los hermanos mayores de los animales incluso cuidan de los pequeños cuando sus padres se van de cacería. ¿Eres un hermano mayor o tienes un hermano mayor?
Can you imagine swooping through the air like Hatzegopteryx, a giant of the ancient skies? Hatzegopteryx (hatz-eh-GOP-ter-iks) was one of the largest pterosaurs that ever lived; about the size of a small airplane. I am Hatzegopteryx, the second book in Arbordale Publishing’s I am Prehistoric series, gives children a glimpse into the life of the awesome Hatzegopteryx, from tiny chick to majestic winged predator, and how it made its living. Unlike many pterosaurs, this one was a terrestrial carnivore, spending its time hunting prey on land. Just like today’s animals, prehistoric creatures had adaptations and behaviors that helped them survive in their habitat—a environment that was in some ways quite different from what we see around us today.
Trees give us yummy apples but also help us build houses. One of these is natural, the other man-made. Can you identify the natural resource? In this edition of The Compare and Contrast Book series, we investigate common items around us and how natural materials are made into tools, toys, and even electricity. After exploring dozens of photos, readers will be a pro at identifying ways we use natural resources from plants, animals, and elements below the Earth’s surface.
Perhaps you’ve seen an otter swimming and playing at a zoo or aquarium, but do you know how do these amazing animals live in the wild? Most are found in freshwater habitats, while others make their home in coastal kelp forests or can be found feeding along rocky shores. There are many similarities between river otters and sea otters, but there are also vast differences. Explore fascinating facts about these playful, aquatic mammals, meet the species, and awe at adorable photos in this latest installment of the Compare and Contrast Book series.
When Loran’s homework assignment is to create an animal’s adaptations and demonstrate how the adaptations help it survive in its environment, he knows just what he wants to do. Loran creates a multipurpose, super species by using all kinds of cool, one-of-a-kind adaptations taken from a variety of some of his favorite animals—like a monkey’s prehensile tail and a sloth’s claws or even curling up like an armadillo. Once he created what he thinks is the ultimate adaptation mashup of any animal ever, he is surprised to discover that his “imaginary creature” really exists—it’s a pangolin! Yes, these charming and unique creatures really do exist, and they are the most endangered animals you’ve possibly never heard of.
Yes, some of the 18 species of penguins live in cold, polar regions, but most penguins live in warm climates. One species even lives near the equator! These birds “fly” through the water with flippers instead of the air with wings. Most are black and white, but one species is blue and white. Some have red eyes, and some have yellow eyes. Some even have colorful bursts of feathers atop their heads. What do they all have in common and how are they different? Explore and learn about these lovable birds in this latest installment of the Compare and Contrast Book series.
Dog detectives? Thanks to superior sniffers, some pups learn to help scientists investigate and track endangered animals. The snoopers’ clue? Poop. Dogs that are part of wildlife detective teams are trained to catch the scent of wild animal poop (scat) so that scientists can learn about these animals without luring or trapping them. Like many pooper snoopers, Sampson, the dog in this book, was once a shelter dog, too hyper and ball crazy for families. That energy and ball drive is what makes him such a good dog detective. He is trained on many species, from salamanders to bears, but his goal is always the same. Find the scat and get the ball!
Everything around us is made from the Earth. Some things are easily replaced, while others are not. Think about the food you have eaten or the energy it took to zoom to school on the bus. What natural resources have you used today, and are they easy to replace? Step through the latest book in the Compare and Contrast series to learn about the world’s resources, how long they take to reproduce, and how technology and ingenuity are helping to relieve the strain on some of our most precious reserves.
Big brothers are amazing! Did you know that big brothers are important in animal families, too? Animal big brothers do many of the same things as kid big brothers. They play with their younger siblings, teach them new things, and help with their care. Sometimes animal big brothers even babysit when their parents leave to hunt for food. Are you a big brother or do you have a big brother?
¿Imaginas caer en picado a través del aire como un Hatzegopteryx, un gigante de los cielos antiguos? El Hatzegopteryx (hatz-eh-GOP-ter-iks) fue uno de los pterosaurios más grandes que han vivido; tenía cerca del tamaño de un avión pequeño. Yo soy Hatzegopteryx es el segundo libro de Arbordale Publishing de la serie Yo soy Prehistórico, el cual le otorga a los niños un vistazo de la vida del grandioso Hatzegopteryx, desde que era una pequeña cría hasta convertirse en un asombroso depredador alado, además de cómo hacía su vida. A diferencia de muchos pterosaurios, este era un carnívoro terrestre, el cual pasaba su tiempo cazando presas sobre tierra. Al igual que los animales del presente, las criaturas prehistóricas tenían adaptaciones y comportamientos que les ayudaban a sobrevivir en su hábitat—un ambiente que era de varias formas bastante diferente a lo que vemos a nuestro alrededor actualmente.
