What is mole-rat queen?
As in some insect species, the queen is the only naked mole rat female to breed and bear young. Worker animals dig the burrows that the whole clan inhabits, using their prominent teeth and snouts. They also gather the roots and bulbs for the colony to eat. Other rats tend to the queen.
What noise do naked mole-rats make?

Are naked mole-rats smart?
While the EQ of naked mole-rats is rather low, several features suggest they may nevertheless be quite intelligent: as outlined above, they communicate widely among conspecifics, they are playful and anticipatory, with even some reports of tool use.
Can I buy a naked mole-rat?

Which is the only representative of the genus Heterocephalus?
The naked mole rat ( Heterocephalus glaber; Fig. 7.30) is the sole representative of the genus Heterocephalus ( Faulkes and Bennett, 2013; Kock et al., 2006 ). Figure 7.30. Heterocephalus glaber – naked mole rat. Side view. Photograph from Cleveland Metro Parks Zoo.
How are Heterocephalus glaber adapted to live underground?
Other adaptations to living underground are their lack of thermoregulation and high circulating hemoglobin and myoglobin concentrations allowing them to thrive in a carbon dioxide–rich atmosphere. 3,4 Native to Ethiopia, Somalia, and Kenya, NMRs build elaborate tunnel systems (up to 2–3 km in length) for colonies that contain up to 300 individuals.
What kind of skin does a Heterocephalus have?
The skin is loose, wrinkled, and brownish pink in color. The body is for the most part absent of hairs with the exception of tactile hairs that are regularly arranged throughout the body and which are particularly prominent around the face and to a lesser extent on the tail. They are typically housed at 28–30°C, and at 50–60% relative humidity.
When does hydrocephalus occur in an older person?
Hydrocephalus ex-vacuo occurs when a stroke or injury damages the brain and brain matter actually shrinks. The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space.
