- CORAIL is a tribute to coral as an ecosystem essential to our survival. -

Livre Corail Martin Colognoli
CORAL book edition


The photographic book CORAIL is an immersion into the fragile world of coral and the communities that depend on it. It captures the solidarity, respect and connection with living things. A world that is both raw and real, and at the same time dreamlike and fabulous. This book is therefore somewhere between art and documentary.

Using powerful, often spectacular images, the French photographer appeals for the preservation of these emblematic ecosystems through an artistic report that retraces six years of field experience.

It is a hymn to the defence of biodiversity and a tribute to coral as an ecosystem essential to our survival.


Co-founded by Martin Colognoli in 2012, Coral Guardian is a French international solidarity association that works to conserve coral ecosystems and the communities that depend on them. The aim is to involve local communities in the restoration, protection and enhancement of coral ecosystems, which have been locally degraded by human pressures.

CORAIL is honoured to have a preface written by two prestigious personalities: Charlie Veron and Denis Allemand.

Born in Sydney in 1945, Charlie Veron is an Australian biologist specialising in the study of corals and their reefs.
He has named around 20% of coral reefs and discovered and delineated the “Coral Triangle”.
Chalie Veron is also an environmental campaigner.

Denis Allemand is a university professor of animal biology and Scientific Director of the Monaco Science Centre. His main area of research concerns the physiology of marine organisms, mainly corals, and their use as model organisms to understand major biological problems (biomineralisation, symbiosis, ageing, etc.).

Available in bookshops and on the HEMERIA website.

Based on an original idea by Martin Colognoli, a team of professionals (art director, publisher, writers, printer, etc.) have given priority to the image.

Firstly, by choosing a large portrait format (34 cm by 25.5 cm) with 156 pages, a silk-screen printed hard cover and paper that is pleasant to the touch.


The layout alternates spectacular photographs of the coral (alive or dead and back to life), portrait photographs and more abstract, contemplative black and white photographs. It shows all the dimensions of Martin Colognoli’s photographic work: both a desire to bear witness and a desire to offer more artistic work that aims to sublimate the coral.


A book is printed in France after a year of collective work, sold for €59 in bookshops or on the HEMERIA website!


Hemeria has teamed up with Printmodel®️ for the production of its books, which will benefit from their unique expertise in the reproduction of images on printed media, with tailor-made choices of paper, printing technology and enhancements (silk-screening, branding).


Printmodel uses only the finest materials, in particular paper from sustainably managed forests produced in accordance with FSC and PEFC standards, to limit its environmental footprint. The CORAIL project will take part in the reforestACTION programme: for every book purchased, a tree is planted.
