Zoologists
Transcript:
Zoologists first began to explore the unusual lifestyle of the naked mole-rat in the 1970s, identifying it as the only known mammal to be ‘eusocial’. Rather like bees, naked mole-rats live in colonies in which powerful ‘queens’ control groups of as many as 300 animals. Researchers soon discovered that this small animal, which is native to East Africa and lives exclusively underground, packs a number of other surprises. It is unique among mammals in being poikilothermic or cold blooded, and is extremely efficient in its use of resources. When the naked mole-rat finds a calorie-packed underground tuber, it eats what it needs and then covers the tuber with soil so that it can continue growing, meaning that the naked mole-rat, like humans - farms its crops.
