Conversational text and soft, crosshatched pen-and-ink illustrations ebb and flow in a fluid look at the largest mammal ever to inhabit the earth. Invoking the senses, Davies describes the blue whale's physical attributes in irresistible, crystalline terms. Its skin is ""springy and smooth like a hard-boiled egg, and it's as slippery as wet soap."" The enormity of the blue whale comes into focus in the illustrations that place it next to a giraffe and an elephant, bringing it into the everyday realm of children. The scale of this leviathan becomes even clearer when Davies notes that its eyes are the size of teacups and its ears are no larger than the end of a pencil. She covers its yearly migration, and its diet of 30 million tiny krill in just a day. Undulating bold text provides auxiliary facts that complement the main story. Effective use of shrinking and expanding typeface and the inclusion of two human observers accentuate the proportional vastness of both the creature and its ocean. This unassuming book is teeming with new discoveries upon each rereading.
