What’s it about?

The story.

The Big Book of the Blue takes young readers beneath the waves in Yuval Zommer's oversized, whimsical spreads, with facts drawn from sea-life consultant Barbara Taylor. Opening pages introduce the families of sea animals, how they move through the water and how they breathe, before the book turns to specific creatures — whales, sharks, sea turtles, stingrays and seahorses — each given its own richly detailed page. Habitat spreads show the teeming life of a coral reef or the strange animals of the deep sea bed, and thematic pages explore how sea creatures hide, glow and survive. Every page is scattered with searchable details and short, memorable facts about ocean life. The large format and picture-book charm make it a natural read-aloud for a four- or five-year-old, while the facts and search-and-find challenges reward older children reading alone. It is a browseable, returnable first reference for any young ocean-lover.

Fit check

Right for your child?

Where it lands by age

Best shared aloud from around 4, when the search-and-find spreads and read-aloud facts land hardest, and read independently by curious 6–9s. A browsing-and-poring book rather than a bedtime read.

How it works in school.

A strong anchor text for an oceans or sea-life topic in KS1/lower KS2, with labelled facts and search tasks children can use to practise retrieval and write their own reports.

Classroom role

  • Topic companion
  • Classroom library

Good for teaching

  • Retrieval
  • Vocabulary

A book children love that happens to support school — never a stand-in for the texts a class is taught with.

Why it lands

Why they love it.

Why kids love it

Sharks, whales, glowing deep-sea fish and the crowded life of a coral reef — Zommer hides creatures to find on every spread, and the facts about who hunts, hides and glows are exactly the kind children love to repeat.

  • Being a detective
  • Secret world

Why parents love it

A big, handsome book that reads aloud to a four-year-old and holds up as a fact source for a curious seven-year-old, with expert facts from Barbara Taylor. The art is beautiful enough that adults enjoy it too.

  • Beautiful illustrations
  • Educational for adult too
  • Conversation starter

Yuval Zommer

Writer & illustrator · United Kingdom

Yuval Zommer is a London-based author-illustrator and environmentalist, best known for his bestselling Big Book nature series. A Royal College of Art graduate who spent years as an advertising creative director before turning to children's books, he creates oversized, whimsically detailed first field guides to the natural world — The Big Book of Bugs, Beasts, the Blue, Birds, Blooms and Belonging — each pairing his warm, richly patterned artwork with bite-sized facts from expert consultants. Every spread is scattered with search-and-find details that reward browsing, turning a wary child's fear of bugs, beasts or the deep sea into curiosity. The large format makes them a natural read-aloud for four- and five-year-olds and a returnable reference for older readers. A go-to for nature-loving 4–8s and the families who share books with them.
