have you ever shared your dinner with a
friend who is hungry then you're more
like a vampire bat than you might have
thought vampire bats practice
hematophagy which means they feed
exclusively on
blood but unlike their mythical
counterparts vampire bats don't actually
suck blood instead they use their razor
sharp teeth to bite mammals typically
horses and cows although sometimes
humans and then lap up the blood that
escapes from the wound fortunately for
their victims vampire bats don't take
enough blood to kill but finding enough
blood to eat isn't always easy vampire
bats hunt on most nights but if they're
unsuccessful for more than two nights in
a row they will starve to death
fortunately vampire bats just like
people are often willing to help their
friends in fact to prevent a fellow bat
from starving female vampire bats will
sometimes regurgitate a portion of their
most recent bloodmeal into the mouths of
nearby female vampire bats but proximity
alone doesn't guarantee this Behavior
vampire bats use a practice called
reciprocal altruism they learn to
recognize bats who've shared with them
in the past and they only share with
them this includes familial relatives
and current or former Roost mates
basically their
friends so far in the wild scientists
haven't found any evidence that male
vampire B BS participate in this food
sharing
process and while the reason for the
Divide between Sexes isn't completely
understood what is clear is that female
vampire bats like humans get by with a
Little Help from their friends
