“The professor’s enthusiasm and Newman’s busy, blocky scenes of sea life and landforms lend extra vim to the adventure […] Just the ticket for budding naturalists with a serious interest in our planet’s remotest reaches.”

"This STEM-focused adventure is perfect for readers who love the 'Who Would Win?' series and animal fact books by Steve Jenkins"
—School Library Journal
“This book is perfect for children over the age of five. It is very detailed and not something that would be read in one setting. Younger children would enjoy having the book read to them and looking at all the wonderful illustrations.”
