A favourite story-telling photo: Male brown crab guarding a newly moulted female that is tucked in behind her old armour

The photographs I get most enjoyment from are those that tell a story about an animal’ s life. That’ s why I find crabs such appealing subjects; they move and act at the ideal speed, slower than fish and faster than starfish or sea anemones! Sometimes, they don’ t even need to move.

A recent favourite was taken while diving on the beautiful Norfolk chalk reef. There, in a small cave-like hollow at the base of the reef, a large brown crab was positioned over another one in a protective pose. This second crab looked rather sickly and as I got down closer, the crustaceans’ story became clear.
The second‘ crab’ wasn’ t a crab at all; it was a now empty but very complete suit of armour. The‘ new’ freshly-moulted crab that had emerged was tucked further back under its guardian, much better protected and largely hidden behind the old armour that acted as a useful barrier. Other aspects of the scene confirmed what was happening: the partly hidden crab at the rear had the newly-moulted‘ fresh’ colouration, the abdomen(‘ tail’ flap) on the underside of the old armour showed it was a female and the white crack visible in the suit showed where its occupant would have been able to slide out.
