Vampire Bats' Unique Energy Source Unveiled by Treadmill Tests

Scientists have discovered that vampire bats use blood-derived amino acids as their primary energy source, rather than carbohydrates or fats, to fuel physical activity. This was determined by observing the bats on treadmills and measuring their metabolic activity. The study found that the bats rapidly oxidize amino acids from their blood meals, similar to bloodsucking insects, highlighting a unique adaptation among mammals.
