We have two species of burrowing crayfish living in the areas surrounding our creeks. When the ground gets a bit wet they'll make chimneys around some of the entries to their burrows.

As they live underground it's rare to actually see one of these crays so my photo below was the first (and still the only live) one of this species, Engaeus tayatea, on iNaturalist.
