Explorers are designed to appeal to all readers aged 6--8: those who are just starting to read alone and more confident readers who are beginning to exercise wider reading and cross-referencing skills. Lively, dramatic artwork scenes draw children into a subject, and each scene is followed by a photographic information spread that gives a wealth of extra detail. As a fun extra element, the reader can follow themed links to access information on related topics. Whales and Dolphins is an adventure to swim with these amazing mammals: the largest animal on Earth, the mammal with the longest migration, and dolphins singing and calling to each other.
Anita Ganeri has written over 300 information books for children on subjects including natural history, religion and geography. Her books include the Horrible Geography series, which won the Geographical Association Silver Award.
