"I've had the pleasure of reviewing all of the books in Meomi's wonderful 'Octonauts' series, which are published by Immedium. I have to say, they just keep getting better and better, and the newest,The Octonauts & the Great Ghost Reef is probably my favorite yet. Not only are the illustrations so cute I want to hang them on my walls, but the story is great, and it's educational... Every page is filled with the cutest illustrations, featuring Meomi's signature characters!"

"The eight cuddly underwater explorers from The Octonauts and the Sea of Shade (2007) take a vacation to the Great Reef City only to discover the wondrous reef ecosystem has become bereft of both life and color. They learn that coral is actually made up of thousands of little creatures, and the buildings built on top of the reef have strangled them of sunlight. Even if children don't quite respond to the gentle socio-environmental message of learning to live in harmony with one's surroundings, the anime-inspired artwork and oodles of minute details bubbling around each page will have them deeply immersed in the fantastical undersea world."

"For many here at COLOURlovers, the illustrations and color compositions found in this brilliant series have continually been a source of inspiration, and The Octonauts and the Great Ghost Reef is no exception." - Colour Lovers

"The illustrations are delightful and a host of reef dwellers are beautifully presented, as other reef neighbourhoods are also explored. Despite this being designated a picture book for children 4-8, The Octonauts & the Great Ghost Reef is another fine example of top quality illustration that makes a fine book for anyone of any age to pore over."

"Kids should be drawn in by the zippy graphics and comprehend the message about conservation."

"The Octonauts are Diesel Oakland's favorite team of underwater animal explorers. Cute, colorful, imaginative, and action-packed, their exploits appear in four volumes...Their mission? To investigate the mysteries of the deep and to help their fellow creatures. Kids will love the fact that The Octonauts have their own unique personalities, a deep sea workstation in which they live and play, and jobs just like real scientist-explorers. Adults will appreciate the cool graphics and quirkyhumor. And both will look forward to the vibrant illustrations and little visual details that make each adventure worth returning to again and again."
