naked mole rat
LowSpecialized (Biology/Zoology), Informal
Definition
Meaning
A small, hairless, eusocial rodent native to East Africa, scientifically known as Heterocephalus glaber.
A fascinating model organism in biological research, particularly for studies of cancer resistance, pain insensitivity, and social structure. Informally, a metaphor for something bizarre, resilient, or unattractive.
Linguistics
Semantic Notes
The term is a compound noun. While it describes a specific species, it is sometimes used loosely to refer to other hairless fossorial mammals (e.g., the Damaraland mole rat). Its uniqueness makes it a high-specificity term.

FAQ
Frequently Asked Questions
They are not completely blind but have very poor eyesight, suited for their dark, underground habitats.
Like bees or ants, they live in colonies with a single breeding queen, non-breeding workers, and soldiers.
They are rodents, more closely related to porcupines and guinea pigs than to true moles or common rats.
They are common exhibits in major zoos and aquariums worldwide due to their unique biology.
