How many fingers do whales have? Why do whales strand on beaches? Do dolphins protect humans from sharks? What does DNA reveal about the ancestry of cetaceans? This comprehensive book is a collective response to thousands of letters and phone calls received annually by the Smithsonian's National Museum of Natural History. Students, teachers, and scientists all have amazingly varied questions about whales and dolphins, and the most revealing inquiries are presented here with detailed answers.
