Crayfish burrow (chimney)

Order Decapoda


I spotted a crayfish burrow ("chimney") on the ground in the woods near a wetland area. It looked like a model volcano made of mud, maybe six inches high. The mouth of the "volcano" was ~1" wide; the base was ~5-6" wide. The "most common species [of crayfish] burrow during the late summer, spend most of the fall and winter underground in water filled tunnels, then move to open water ... ."

I consulted an expert on the crayfish of HMP. The type of crayfish that creates the chimneys is unknown. It is believed the chimney-building crayfish live in the burrows year-round: the crayfish emerge from their burrow at night and move to the water to feed; the crayfish return to their burrow in the morning. The expert tried and failed to trap one of these crayfish; she is considering alternate plans for building a trap.
