17 Draculin, a protein present in the saliva of vampire bats, prevents the blood from clotting while the bat feasts on the blood of its prey.

Draculin is a protein found in the saliva of vampire bats. Vampire bats drink blood to sustain themselves. The vampire bats do not suck the blood from their prey.
