Species classified as Primary burrowing crayfish will still crawl out of a pond filled with great habitat and make chimney burrows. They can't 'help it', It is in their genetic make up. It is what they do when the reproduction urge 'strikes'. Secondary burrowing crayfish rarely burrow and usually crate shallow burrows depending on the species and habitat conditions.
