"Look Who Lives in the Ocean" by Alan Baker is a beautiful hardbound book with wonderful sealife illustrations.
Each page is filled with a depiction of life under the ocean accompanied by well-written clues as to what sea-creature is being described. Also on the page is a small glimpse of the creature. Upon turning the page the sea-creature is revealed in another full page illustration with a new clue written as to who the next creature is. Along the border of that page is a small headshot (or other small glimpse) of the next creature.
The book is very educational for lower elementary grade levels. Preschoolers will also enjoy this book due to the colorful illustrations and limited written text.
At the back of the book is a map of the continents and oceans of the world. Also, there is a page with an expanded description of each of the sealife creatures.
