Built for an ant-and-termite diet, aardvarks use a 30 cm sticky tongue, enamel-free continuously growing teeth, and powerful claws to dig extensive burrows that shelter many other species, making them vital ecosystem engineers across sub-Saharan Africa. They cover fascinating adaptations (nostrils that seal shut while digging, an extraordinary sense of smell, bursts of speed up to 40 km/h), along with behavior, reproduction, and lifespan. Although listed as Least Concern by the IUCN, aardvarks face emerging pressure from climate-driven drought, which reduces insect prey and may be causing regional declines. The episode closes with conservation insights and ways listeners can support habitat protection efforts.
