Pallas's Long-tongued Bat

Fascinating facts about the Pallas's Long-tongued Bat

• A tongue nearly as long as its entire body unfurls from a bat the size of a thumb — Pallas's long-tongued bat's tongue reaches 8.5 centimetres, compared to its 6-9 cm body length. When retracted, it coils down the throat past the ribcage like a fire hose. This architecture lets it drain flowers blooming deep inside curved corollas that no other mammal can reach, making it an irreplaceable pollinator for hundreds of tropical plants.
• Hovering in mid-air while drinking nectar, this bat burns through calories so quickly it must feed every 10 minutes or risk starvation — a metabolic rate so extreme that a human equivalent would need to eat 150 hamburgers daily just to survive. At night, a single bat visits up to 1,300 flowers, and its body temperature drops to match the ambient air when it rests, a survival tactic that slashes energy demand by 95 percent.
• The bat's brain shrinks and grows with the seasons depending on food availability — up to 20 percent smaller when nectar runs low in the dry season, then rebuilds itself when blooms return. This neural plasticity, unknown in most mammals, suggests the brain rewires on demand rather than staying fixed, challenging everything we thought about mammalian neurology.
• Pollen clings to the bat's face and body as it feeds, coating its fur with a yellow dust that it grooms and swallows, obtaining vital proteins and minerals nectar alone cannot provide. A single bat can carry pollen loads of 250 milligrams — roughly its own body weight in stuck pollen — effectively acting as a living agricultural worker for rainforest reproduction.
• These bats roost in large harems of up to 40 females per male, a social structure rare in bat species, where the male aggressively defends access to all breeding females through the year. This polygynous system, paired with their dependence on flowering plants scattered across the forest, means population crashes ripple instantly through plant reproduction across thousands of hectares of rainforest.
