Zommer's incredible Big Book series takes to the sea in this third installment — and it is as delightful as ever. Why do octopuses have eight arms? Why do crabs run sideways? Are jellyfish made of jelly? The facts are funny and genuinely astonishing, and the illustrations give every slippery creature its own irresistible personality. I enjoy this series just as much as my kids do. A perfect gift for the curious child in your life.
