The hints given refer to the continent(s) where attacks have been documented. If blank, the animal is sufficiently widespread that any inhabited continent may apply.

This is about animals that have both killed and, at least partially, consumed humans. Scavenging doesn't count. Killing without eating doesn't count.
Controversial or inconclusive cases have been excluded.
Hint: Some of these are small animals working in groups.
