(FOX40.COM) — After months of planning, the Sacramento Zoo announced it’s bringing a naked mole-rat colony for the first time in the zoo’s history.
According to the Sacramento Zoo, the colony offers guests a glimpse into these “unusual rodents.”
The naked moles are now settling into their newly built habitat inside the Kenneth Johnson Reptile house. However, have you ever wondered why they’re “naked”? Brandson Fuentes, Animal Care Supervisor at Sacramento, said they evolved to be fossorial.

“They really don’t need it. So they’ve evolved to be fossorial, which means that they live almost their entire life underneath the ground,” Fuentes said. “Which means, the need for thermoregulating or to shed water or any of those sorts of things that you typically see in haired mammals, they just don’t have the need for it. You know, underground there the temperatures stay nice and stable, so they’re not seeing a big temperature fluctuation, like you would with other species… so it’s just really a need, they didn’t have the need for it.”

Funtes said these unusual rodents operate much like an ant colony or beehive and can live surprisingly long, often reaching their 30s.
Zoo officials said naked mole-rats are a nearly hairless, subterranean rodent that is found in parts of eastern Africa, such as Somalia, Djibouti, and Kenya.

According to Zoo authorities, the mole-rats have no external ears and are nearly blind due to their incredibly small eyes. They rely on smell, ground vibrations, and air currents to navigate.
The naked mole-rats also have an incredibly complex social structure within their colony, with designated roles in the colony such as soldiers and caretakers, officials said.
Just like bees, the naked mole-rat colonies are also headed by a queen as the matriarch and only breeding female of the group. Queens grow larger after each of their first eight litters, with established queens able to produce litters of 28 pups.
The naked mole-rat exhibit will remain at the Sacramento Zoo indefinitely.
