Furthermore, the team found, the mole-rat somatosensory cortex is significantly larger relative to the size of the entire neocortex than that of closely related lab rats.

The great disparity of dental structures and dynamics in rodents: More—and older—mole rats are needed to be sure that the risk of dying really is flat, Finch argues.

Given that rodents are mammals like us, the mole-rat's features are intriguing.
As can be seen in Figure 1naked mole-rats have a streamlined cylindrical shape, with no external ear pinnae, and the males also have internal testes; so it is extremely difficult to distinguish males from females within the colony. Several developmental studies on other mammals, such as minipig, ferret and mainly humans, provided complementary data on tooth replacement e.
Several litters of different ages are present within the colony and most individuals will stay and work in the colony in which they were born throughout their long lives.
