Wildlife photography, science communication, and showcasing the wonders of the natural world through the lens of Martin Stevens.
Martin Stevens is a scientist who studies animal coloration and behaviour. For his day job, he is a Professor of Sensory and Evolutionary Ecology at the University of Exeter, Cornwall Campus and runs a research group that studies animal coloration, behaviour, and vision, including our own impact on the world.
In his research he has long-used digital imaging techniques to study the science of animal coloration and vision. Outside of his main job, he is a keen underwater photographer, determined to capture the wonderful animals and scenery of UK marine environments, including many of the remarkable but lesser-known species. In particular, he aims to show off the creatures and underwater worlds close to home around Cornwall.
Alongside wildlife photography, he has written a number of popular science books, including in 2021 Life in Colour, (BBC Books, February 2021) which accompanied the David Attenborough BBC TV series, as well as most recently Secret Worlds (Oxford University Press, June 2021) all about remarkable animal senses.
