Badgers, moles, voles, rabbits and some bears.
Dens are made usually by the female wolves that are going to have pups. How they make the dens are quite simple, a wolf looks for a good tree to dig under and then she digs a small enough hole in which the wolf could easily move around in with her pups. Most times the den is made with a little distance away from the pack's usually hangout area so that the den is far away enough that the other wolves wouldn't disturb but close enough for the pack to quickly arrive if there's some sort of danger.
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
A lair is nothing but a resting (and nesting) place for an animal.
Roots are important to plants because the roots control the whole part of it. If the plant had no roots then it could not absorb water and nutrients to keep the plant alive.
2nd cervical vertebra (axis) has dens (also called odontoid process).

Dens
Many small animals live in burrows, or dens. Some small birds will make nests on the ground.
Raccoons do not typically live underground. They usually make their dens in tree cavities, burrows, hollow logs, or dens in rock crevices. They are adaptable animals and can also make their homes in attics, barns, or other man-made structures.
Minks make their dens in trees rocks logs and underground.
Dens can be found in various environments depending on the animal species. For instance, foxes often create dens in wooded areas or fields, while bears typically use caves or hollowed-out trees. In aquatic environments, some animals like beavers build dens in riverbanks. Overall, dens are strategically located to provide shelter, protection, and proximity to food sources.
No they only sleep in trees
Animals that live in dens include bears, foxes, wolves, badgers, rabbits, and groundhogs. Dens provide shelter and protection from predators and the elements for these animals. They are used for sleeping, raising young, and storing food.
