Cuando la tarea de Loran es crear las adaptaciones de un animal y demostrar cómo estas adaptaciones le ayudan a sobrevivir en su entorno, él sabe exactamente lo que quiere hacer. Loran crea una súper especie polivalente usando todo tipo de adaptaciones geniales y únicas tomadas de una variedad de sus animales favoritos, como la cola prensil de los monos, las garras de una pereza e incluso la capacidad de enroscarse como un armadillo. Una vez que ha creado lo que piensa que es la más increíble mezcla de adaptaciones animales de todos los tiempos, se sorprende al descubrir que esta “criatura imaginaria” realmente existe—¡es un pangolín! Sí, estas encantadoras y únicas criaturas realmente existen, y son los animales con más peligro de extinción sobre los cuales quizá nunca has escuchado.
Sí, algunas de las 18 especies de pingüinos viven en regiones frías y polares, pero algunos pingüinos viven en climas cálidos. ¡Una especie incluso vive cerca del ecuador! Estas aves “vuelan” a través del agua con aletas en lugar de en el aire mediante alas. La mayoría son blancos y negros, pero una de las especies es azul y blanca. Algunos tienen ojos rojos y otros tienen ojos amarillos. Algunos incluso tienen ráfagas coloridas de plumas sobre sus cabezas. ¿Qué tienen en común todos y cómo se diferencian? Explora y aprende acerca de estas aves adorables en la entrega más reciente de la serie de Un libro de comparaciones y contrastes.
¿Perros detectives? Gracias a sus extraordinarias habilidades para olfatear, algunos cachorros aprenden a ayudar a los científicos a investigar y rastrear a animales en peligro de extinción. ¿Tras qué pista van? La caca. Los perros que son parte de los equipos de detectives de la vida salvaje están entrenados para captar el olor de la caca (excrementos) de los animales salvajes para que los científicos puedan aprender de ellos sin tener que atraerlos o atraparlos. Al igual que muchos cazadores de caca, Sampson, el perro en este libro, solía vivir en un refugio, era demasiado activo y alocado para las familias. Esa energía e impulso es lo que lo hace tan buen detective. Está entrenado para seguir a muchas especies, desde salamandras hasta osos, pero su meta siempre es la misma. ¡Encontrar la caca y capturar la pelota!
Todo lo que nos rodea está hecho con recursos naturales. Algunas cosas son fáciles de reemplazar, mientras que otras no.

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?
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.

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.
