Definition
Noun: 1. A specific reproductive female in a eusocial colony: The "queen mole rat" is the single, primary breeding female within a colony of naked mole rats (Heterocephalus glaber). She is responsible for producing all or nearly all of the colony's offspring. 2. A distinct physical caste: This individual is not just a behavioral role but a physiological caste. The queen mole rat is typically the largest member of the colony, a condition triggered by and sustained through her reproductive dominance.
Usage Examples
- Noun:
- The queen mole rat is the center of the colony's social structure.
- Only the queen mole rat and a select few males reproduce.
- Researchers observed how the queen mole rat suppresses the reproduction of other females in the colony.
Advanced Usage
- "to become the queen mole rat": This phrase describes the process where a female mole rat ascends to the breeding position, often through competition, which triggers significant physical growth and hormonal changes.
- When the previous breeder died, a subordinate female fought to become the queen mole rat.
- "reigning queen mole rat": Emphasizes the current, dominant breeding female's rule over the colony.
- The reigning queen mole rat has produced over a hundred pups in her lifetime.

- Reproductive suppression: The physiological process by which the presence and dominance of the queen mole rat inhibit the reproductive systems of other females in the colony.
Noun
- an especially large mole rat and the only member of a colony of naked mole rats to bear offspring which are sired by only a few males
