flic.kr/p/2s9fjnQThe morning light on Cox’s Bazar beach in August 2023 was a particular kind of soft — diffused, humid, before the heat hardened into glare. It was in that light that I noticed them: two red crabs, vivid as embers, emerging from the same burrow in the sand.
Ocypode haematochetra — the painted ghost crab — is native to this coastline, and to beaches across the Bay of Bengal. Their red colouring deepens with age; juveniles are pale, almost translucent, like the sand itself. But these two were fully adult, fully saturated in that improbable scarlet, their stalked eyes raised above the burrow’s edge with the alertness of creatures that have survived everything the tide and the tourists have brought.
They are not decoration. Red crabs are ecological engineers. Their burrows — which can reach 60–80 centimetres into the sand — aerate the beach, cycling oxygen and nutrients through substrate that would otherwise compact and die. They are scavengers and predators both, consuming detritus, small invertebrates, even sea turtle eggs when the opportunity presents itself. Their population density is, in some studies, used as a bioindicator of beach health: more crabs, healthier beach.
At Cox’s Bazar — the world’s longest unbroken natural sea beach — the red crabs once moved in great visible populations at dawn and dusk. Fishermen knew them. Children chased them. They were simply part of what the beach was.
Today, their numbers are under pressure. Beachfront development, artificial lighting (which disrupts their nocturnal behaviour), sand compaction from vehicle traffic, and plastic pollution have each taken a toll. You still see them — as I did that August morning — but you have to look, and you have to be there early, before the beach fills with noise and footfall and the crabs retreat deep into their tunnels.
Two crabs, one burrow, one morning. A small and specific encounter. But in it, something about the beach’s own insistence on continuing — on pushing back, tentatively, against the surface that threatens to bury it.
