Vampire Bats | National Geographic

here are some happy vampire bats what’s
causing all this giddiness a great big
bad meal has arrived you can practically
hear these bats going oh boy Oh better
yet the victim is asleep this is gonna
be like well taking blood from a
sleeping Pig the bats have heat sensors
in their noses this thermal process lets
us see what the bat sees the bat wants
to feed where the pig skin glows white
hot let the dining commence like to
wildcatters fighting over a fresh oil
striper these bats battle over a
particularly rich feeding spot for
vampire bats one sleeping pig why
doesn’t the pig wake up because the bats
teeth are razor sharp and cut painlessly
the bats can sip to their heart’s
content with a pig none the wiser the
bat saliva actually prevents the blood
from clotting as the bat since the blood
runs up a groove on the underside of its
tongue mother nature thinks of
everything these vampire bats can feast
for a full half-hour drinking half their
weight in blood in a month of feedings
five vampire bats can guzzle almost a
gallon of pig’s blood in this case it’s
the bats making a pig of themselves
