“Children appreciate anatomically correct depictions,” notes Zommer. “When I draw, I try to understand the creature’s shape, movement and colour palette, then add in the detail. I always think: ‘What is its essence?’” He worked with sea life expert Barbara Taylor to ensure that “everything is factually robust, as well as asking what would be fun to discover – those quirks and surprises.”
From interacting with fans of his books on social media and at events, Zommer knows they’re adopted by a wide age range, so he takes care to include elements for everyone: from striking visuals for non-readers through to fascinating facts for those who are knowledgeable about the topic. Appropriate analogies help readers connect (such as comparing sea turtles’ sight to swimming goggles), and there’s plenty of wit to make parents smile.
