This competition, launched in France by the CNRS in partnership with Acfas (Association canadienne-française pour l’avancement des sciences), invites scientists to submit their best images, reflecting their research.

A jury made up of representatives from the CNRS Communications Department, Acfas, institutions dedicated to scientific culture and scientific photographers and journalists is responsible for selecting the 20 photographs that will make up the final exhibition.

“The scream”

Reef builders, bryozoans with carbonate skeletons are sub-millimetre multi-cellular organisms. These small animals, which live in colonies at all latitudes, play a major role in regulating the climate by storing CO2 dissolved in seawater in their mineral structure. Here we are at the tip of the skeleton of a colony of bryozoans of the species Cellaria fistulosa. Each organism lives here in a kind of calcium carbonate box with openings, including a main one that allows the animal to filter the seawater and feed. A dozen or so of these “boxes” can be seen; the ones at the top are still being made. This surprising shape is the random result of the colony’s gradual growth. Researchers are trying to gain a better understanding of the resistance of bryozoans to environmental disturbances in a context of ocean acidification.
