Large ears: Gerbils have large ears that help them to dissipate heat.
Pale fur: Their pale fur helps to reflect sunlight and keep them cool.
Nocturnal: Gerbils are active at night, when the temperatures are cooler.
Long tails: Their long tails help to store fat, which they use for energy when food is scarce.
Burrows: Gerbils live in burrows that they dig in the sand. These burrows help to protect them from the heat and the cold.
Water conservation: Gerbils are able to conserve water by excreting very little urine and by reabsorbing water from their feces.
