Praying Mantises

praying mantisesPraying Mantises: Hungry Insect Heroes (Insect World) by Sandra Markle

Finally, a book about praying mantises that doesn’t perpetuate the myth that female praying mantises always eat their mates. Sandra Markle writes in Praying Mantises: Hungry Insect Heroes, “Scientists report that mantises rarely do this in the wild.” It turns out that the myth was started when people kept praying mantises indoors to observe them. Female mantises require a lot of food to produce eggs and the people who fed them rarely supplied enough. The ravenous females ate anything presented to them at that point. When kept outside, the praying mantis often has enough to eat and her mate doesn’t become lunch.

Sandra Markle starts with a detailed look at the outside and the inside of a praying mantis. This is helpful for someone who has never looked closely at a praying mantis. Throughout the book are fabulous photographs and quick “mantis facts” that help capture a reader’s attention as he or she skims through. At the end, between “Digging Deeper” and the index, there are two activities. The first, strike time, relates to how extremely fast a praying mantis can grab its prey. The activity is easy to do and doesn’t require a mantis. The second is to observe a mantis up close in a jar for a day or two and then let it go. Just remember from above, it is hard to keep a praying mantis well fed.

We have had a praying mantis on the same plant for weeks now. Every morning we check to see that it is still there, and we’ve developed a fond feeling towards it. After reading this book we can now take our observations to another level.

Penguin Secrets Revealed

secret-of-the-puking-penguinsSecret of the Puking Penguins . . . and More! by Ana María Rodríguez

Secret of the Puking Penguins and the other books in the Animal Secrets Revealed! series are actually well kept secrets themselves. Hidden behind the blaring, attention-grabbing titles are serious books for kids interested in real science. Ana María Rodríguez interviews five actual scientists about their research and describes new and interesting discoveries that they have made.

In the first chapter, scientists Anthony Herrel and Jay Meyers investigate how chameleons’ incredible tongues work. The tongues are not only sticky, as many of us already knew, but also are physically shaped to act like a suction cup. As the activity at the end of the chapter demonstrates, the suction cup action works much better at grabbing prey than stickiness alone.

The second chapter is about sensory apparatus in alligators. It isn’t until the third chapter does the reader find out about the “puking penguins.” As anyone who lived through the penguin craze of a few years back knows, penguins regurgitate food to their chicks. Rodríguez discusses how three French physiologists are so fascinated by the king penguins’ ability to hold food in their stomachs for long periods that they decided to study it further. By taking samples, the scientists revealed the penguins produce numerous antimicrobial substances (antibiotics) in their stomach to help preserve the food, including one completely new substance that no one had discovered before! How cool is that?

The final two chapters are about research of cuckoos, a bird that lays its eggs in the nests of other birds, and about how peacock feathers create their iridescent colors. “Chapter Notes” at the end are numbered references from each chapter. This is a nice touch that parallels how literature would be cited in an actual scientific paper, getting budding scientists ready to produce the real thing.

Other than the author should have included a few more activities to reinforce learning (there is just one), this book is fascinating and informative for young readers interested in science. Now let’s get the secret out.

Bouncing Baby Spiders

Babies are always cute, but some people might have trouble with using the words cute and spider in the same sneakyspinning-baby-spiderssentence. Those readers may change their minds after picking up Sneaky, Spinning Baby Spiders by Sandra Markle. In this book Markle has combined spectacular photographs of baby and adult spiders with carefully crafted text. For example, the photograph on page five of a jumping spider flying through the air as it pounces is amazing.

The accompanying text is exactly the right balance of factual and lively to make it informative and fun to read. It must have been difficult not to slip into anthropomorphism when the subject is babies, but the author kept just the right tone. Markle writes “mother spider,” but not “mom.” She also uses feminine pronouns instead of the neutral “it.” Those touches draw the young reader in.

Although the author has done a great job with the text, I did find one inaccuracy. Whenever an author is not an expert on a topic and has to rely on others for photographs, a chance for errors creeps in. In this case, the spider identified on page 24 as a “slender sac spider,” genus Chiracanthium, is actually a giant crab spider, genus Olios. One the plus side, the photographs also represent spiders from throughout the world, instead of from only one area or continent as so often is the case.

At the end of the book, the map of where the spiders are found is a nice touch. I also like Markle’s paragraph about how she was inspired to write this book by finding a spider’s web intact after a severe storm. It is a warm, personal note that sets the tone for the entire book.

All in all, Sneaky, Spinning Baby Spider is a wonderful addition to any library.

Another Way to Find Book Reviews

Have you ever been looking for book reviews on a certain book, and not felt you have gotten all you could have from the search? I know you probably have already discovered this, but when searching for book reviews of Dinotrux, I accidentally found a new way to search for book reviews. Instead of searching for “Dinotrux book review” in the web, try “Dinotrux” in images.

Results of a standard web search:

search11

(Note: I did this search yesterday and I don’t know how my post ended up on the first page. It’s a fluke, I’m sure.)

Here’s what an image search looks like:

search2

Seems like a lot more and better options, although maybe that’s because I’m a visual person.

In any case, I’m going to try to include images of the cover from now on so people can find my reviews. Up to know I have just added Amazon links, which has been fast and easy and gives readers a quick way to find out more, but wouldn’t show up in an image search.

I am very curious what you think. Did you already know about searching by image? What do you think of searching by image, does it lead to more finds? How do you include book cover images in your reviews and why?
