So why haven't we evolved the ability to drink the nutritionally and ethically dubious substance? The vampire bat has a small body with large wings on either side. These digestion-assisting and immunity-protecting bacteria would likely have been incorporated into the microbiome alongside changes to the bat's genome. Using bloodmeal and faecal samples from common vampire bats from coastal, Andean and Amazonian regions of Peru, we showcase metabarcoding as a scalable tool to assess vampire bat population structure and feeding preferences.

By examining vampire bats' DNA, scientists say they have uncovered some of the ways vampire bats survive on their 'extreme' germ-laden, low-carb, vitamin-deficient diet of just blood.

Diet of the Vampire Bat These bats feed exclusively on animal blood, this is called hematophagy. By examining vampire bats' DNA, scientists say they have uncovered some of the ways vampire bats survive on their 'extreme' germ-laden, low-carb, vitamin-deficient diet of just blood. This finding contradicts several previous studies that considered D. ecaudata the species with the most specialized diet among vampire bats, feeding exclusively on bird blood in natural conditions ( Villa-R., 1966 ; Villa-R. et al. Then, by cutting out the insect middleman and consuming solely blood, they reduced all competition from other animals who would otherwise be eating their meals. pointed canines and blunted molars of an omnivore, Vampire bat's blood-only diet 'a big evolutionary win', Wood-inspired cement with high strength and multifunctionality, A third of rivers in US found to be changing from blue to green and yellow, Full mitochondrial control for the ultimate anticancer biohack, Model estimates subsidence risks across the globe, 2 questions: illusory "force" between hands, and "wave genetics".
