What is "bukavac"

Bukavac is a demonic mythical creature in Slavic mythology. Belief in it existed in Srem.

Bukavac was sometimes imagined as a six-legged monster with gnarled horns. It lives in lakes and pools, coming out of the water during the night to make a loud noise (hence the name: buka - noise), jump onto people and animals, and strangle them.
