Las nutrias / Otters at the Zoo [PDF ebook] 

Otters move so fast in their habitat at the zoo, sometimes it can be difficult to get a good look at them. With this book, beginning readers get much more up-close and personal with adorable otters. Including what otters eat and how they spend their time, the main content and language is age-appropriate for pre-K readers. Full-color photographs correlate to the otter information to further aid new readers as they swim along with otters at the zoo.
