With photographs by Alex Mustard and text by Callum Roberts, Secrets of the Seas, published in September 2016 by Bloomsbury, is a visual voyage to some of the richest and most exciting places in the world's oceans. With chapters covering a range of habitats from the Pacific's Coral Triangle to the North Atlantic and the ocean's seaweed cathedrals, the book showcases Alex Mustard's extraordinary photography, with remarkable close-ups of a diverse range of the ocean's inhabitants.
“This isn’t a title to read just once, but one into which you’ll continue to dive – to escape, to be entertained, and to become better informed about our fascinating, spectacular oceans.” – BBC Wildlife
