Join the Cat in the Hat and the Fish as they introduce beginning readers to the many different kinds of creatures that live in or near the sea. This title and others form part of a series of books that takes an off-beat look at nature and natural sciences through a fun combination of Seussian rhymes and zany illustrations. Aimed at early readers  from four to seven year olds  the books are designed to bridge the gap between concept books written for preschoolers and more formal non fiction titles that require fluent reading skills. By presenting the facts in a lively and rhythmic manner, they provide the critical foundation upon which complex facts and ideas can eventually be built.
