The facts are accurate and give enough description without overwhelming the reader. The book is very organized with every four pages dedicated to the same animal. The text is always in the left upper corner so the students know where to look.

The illustrations are beautifully done, both the close ups and the full pages. I would definitely used the book for an interactive read aloud in the younger grades. The book is intended for emergent readers but I think some of the vocabulary would be a little difficult. The book is a great one to have children to listen to the text and look at the pictures to put together what animal is being described. The end of the book has an instructional glossary with even more facts about the animals. The child must guess what animal he/she thinks it is and turn the page to see if they are correct and learn more facts about the animal. The book gives several clues along with a close up picture of several black and white animals. Evaluation: The book is a great one to have children to listen to the text and look at Illustrated by Phyllis Limbacher Tildes One study analyzes that zebras have more stripes in hotter habitats.Illustrated by Phyllis Limbacher Tildes Published: 1996 Non-fiction, Puzzle picture book Summary: The book gives several clues along with a close up picture of several black and white animals. This would create convection currents around the zebra that would cool it. Air may move more quickly over black light-absorbing stripes while moving more slowly over white stripes. Further, attractiveness increases with stripe width, so the relatively narrow stripes of the three living species of zebras should be unattractive to horseflies.ĥ. These flies are attracted to linearly polarized light, and the study showed that black and white stripes disrupt the attractive pattern. A 2012 experiment in Hungary showed that zebra-striped models were nearly minimally attractive to tabanid horseflies. Experiments by different researchers indicate that the stripes are effective in attracting fewer flies, including blood-sucking tsetse flies and tabanid horseflies. Although the striping pattern is unique to each individual, it is not known whether zebras can recognize one another by their stripes.Ĥ. The stripes may serve as visual cues and identification. The stripes may help to confuse predators by motion dazzle-a group of zebras standing or moving close together may appear as one large mass of flickering stripes, making it more difficult for the lion to pick out a target.ģ.

In addition, even at moderate distances, the striking striping merges to an apparent grey.Ģ. The vertical striping may help the zebra hide in the grass by disrupting its outline.

The more traditional of these (1 and 2, below) relate to camouflage.ġ. The stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal.Ī wide variety of hypotheses have been proposed to account for the evolution of the striking stripes of zebras. It is likely that the stripes are caused by a combination of factors. Embryological evidence, however, shows that the animal's background color is black and the white stripes and bellies are additions. It was previously believed that zebras were white animals with black stripes, since some zebras have white underbellies. It can weigh up to 350 kg (770 lb), males being slightly bigger than females The common plains zebra is about 1.2–1.3 m (47–51 in) at the shoulder with a body ranging from 2–2.6 m (6.6–8.5 ft) long with an 0.5 m (20 in) tail.

While plains zebras are much more plentiful, one subspecies, the quagga, became extinct in the late 19th century – though there is currently a plan, called the Quagga Project, that aims to breed zebras that are phenotypically similar to the quagga in a process called breeding back. Grévy's zebra and the mountain zebra are endangered. However, various anthropogenic factors have had a severe impact on zebra populations, in particular hunting for skins and habitat destruction. They occur in a variety of habitats, such as grasslands, savannas, woodlands, thorny scrublands, mountains, and coastal hills. The unique stripes of zebras make them one of the animals most familiar to people.
