About this book

An octopus that recognises individual faces. A shark that returns to the same reef year after year. Whale songs that spread between oceans like music.

Secrets of the Ocean gathers what marine researchers have genuinely observed — sourced, dated, and free of the myths that usually surround the deep. Written to be read in one sitting and remembered far longer.

Delivered as an illustrated PDF you can read on any device.

Proceeds support our mission to protect animals and oceans, and to bring more true stories of hope into the world.
