Naked Mole Rat

- Workers
Smaller workers focus on acquiring food and maintaining tunnels, while the larger workers are more reactive in case of attacks. As in certain bee species, the workers are divided along a continuum of different worker-caste behaviors instead of discrete groups. Some function primarily as tunnellers, expanding the large network of tunnels within the burrow system, and some primarily as soldiers, protecting the group from outside predators. Workers are sterile when there is no new reproductive role to fill.
- Colonies
Colonies range in size from 20 to 300 individuals, averaging 75 individuals.
