Ecology, Habitat, & Behavior
The common refrain to crayfish is that not much is known about their life cycle certainly applies here. Interestingly, they’re commonly used in aquaculture, so it’s possible that while this information may not be widely published in the scientific community, it is more common knowledge commercially.
White River crayfish are common in a wide range of slow water habitats (sloughs, lakes, , and can dig extensive burrows to avoid drought and cold (though they are a more temperate species). In the fall, males will enter the burrows of females for mating. Their gills are capable of uptaking atmospheric oxygen while in their burrows (though they still require moisture to do so). Their burrows can be 30-40cm deep and terminate in an open chamber. The entrances to burrows are marked by chimneys that can be as much as 6″ high.
