The naked mole rat is an exceptional species, both for its extraordinary biological characteristics and its social structure resembling that of insects. BIOPARC has two groups of these creatures in a specially designed facility to observe their peculiar behavior, where the latest litter can also be seen. The stunning video of the birth would be impossible to witness in the wild and allows for increased knowledge about this impressive animal.

August 2021. A litter of naked mole rat can already be seen in the Bioparc Valencia in Spain, a very strange and unknown mammal that behaves like an insect, is practically immune to cancer, can change from cold to warm blooded, has developed four mobile teeth, is extraordinarily long-lived and, in the absence of oxygen, acts like a plant.

Given its relevance from the biological point of view, BIOPARC Valencia houses a large group of approximately 100 individuals structured in two completely independent colonies. Each one usually reproduces annually and this summer a new litter of 9 offspring has been born that we can see even suckling from their mother. We can contemplate them in the area that recreates the underground life of the Savannah, through windows where the network of tunnels and rooms that imitate their original habitat can be observed.

A Giant Zambian Mole-rat pup born on June 22 is the first surviving second generation of this species at the Peoria Zoo.

The most notable feature of Mole-rats is a pair of large incisors that lie outside the mouth.  Giant Mole-rats excavate their burrows by biting at the soil with their incisors, pushing it under their bodies with their forefeet and kicking it backward with their hind feet.

Peoria Zoo was the first recorded institution in the United States to exhibit this species.  Peoria Zoo and its partners imported Giant Zambian Mole-rats from South Africa for exhibition and research in the United States in 2006.   Since their arrival zoo staff has been working to find a management technique to ensure breeding success. 

Ashley, the pup’s mother, born in 2008, was the first offspring ever to survive at the Peoria Zoo.   

At six weeks of age the Mole-rat pup weighs less than one ounce (24g), but will grow to weigh more than 1.3 pounds (600g).  Pups have dark brown fur, while adults are buff -colored.
