Aggression - Competitive Animals

by Brent Uhing

Aggression is...

"Aggression - A threatening behavior that one animal uses to gain control over another animal."


Animals show aggression when competing against other animals for a similar goal. This behavior involves potential harm to other animals.

Animals get aggressive over many different things: food, mates, land, and much more.
