With its smooth, torpedo-like shape, the seal is a phenomenal deep-sea diver. This zoology title for children, filled with beautiful photos and factual life science text, examines the marine mammal's anatomy, hunting and feeding habits, life cycle, and pup care. Its ocean habitat is described, too. A backmatter feature discusses selkies, mythical Celtic creatures known for disguising themselves as seals. Part of Creative Education's popular Planeta animal series, this North American Spanish translation supports elementary-aged readers with captions, on-page definitions, and an index.
