Pallas's Long-tongued Bat (Glossophaga soricina) lives in tropical rainforest across Central and South America. Its conservation status is Least Concern.
Fascinating facts about the Pallas's Long-tongued Bat
- Pallas's long-tongued bat burns sugar faster than any other mammal, running a metabolism that rivals hummingbirds. It can tap straight from the nectar it drinks, fueling 100% of its energy needs in under thirty minutes, and over 80% of its daily power comes directly from those simple sugars. Because it uses half its stored fat each day.
- The bat's tongue works like a hydraulic mop. When it sticks its tongue out, blood rushes into tiny hairs at the tip, swelling them into erect rows that increase the tip's length by more than 50 %. This sudden expansion creates a pressure-driven flow that pulls nectar up the tongue like a tiny pump.
- A single bat can drink more than its own weight in nectar each day, up to 150 % of its body mass, and still lose almost 60 % of its fat stores every 24 hours. This extreme intake fuels its rapid metabolism, but it also means the animal lives on the edge: any short-term loss of flower resources could starve it before it can rebuild its fat reserves.
- Reproduction is a race against time. After a gestation of about 106 days (roughly 3.5 months), females usually give birth to a single pup that clings to the mother's belly. The newborn can hang on its own by day 18 and learns to fly by around day 26, while captive bats can live up to ten years, giving the species a narrow window to replace each generation.
- Social foraging ranges from tiny defended patches to marathon trap-lines. Some bats guard territories smaller than 10 m² and chase rivals up to 30 m away, while others follow fixed routes of 150-250 m, with the longest recorded at 1 450 m. Colonies can swell to about 1 000 individuals, showing how flexible their feeding strategies are in the neotropical forest.
