This large-sized informative compendium is the kind of non-fiction that children like to come back to again and again to pore over its pages. Each double-page spread dives into a different sea-themed question, such as ‘Are jellyfish made of jelly?’ or ‘Why do crabs run sideways?’. There is never too much text on each page, but what you find is accessible chunks of information cleverly interspersed into each ocean scene. The illustrations are stunning and come together to make wonderful spreads that serve as a treasure trove of visual delights for young eyes, as text and pictures work together to build an understanding of underwater habitats and the life they hold.
