What behavior is characterized by aggression, such as growling or snapping?

The behavior characterized by aggression, such as growling or snapping, is referred to as Fight Mode. This mode is a response to perceived threats where an animal may feel cornered or compelled to defend itself. Instead of fleeing, the animal exhibits aggressive behaviors as a way to intimidate or confront what it sees as a danger.

In contrast, Flight Mode and the Flight Response are associated with avoidance behaviors where the animal prefers to escape from a threat rather than confront it. The Fear Response encompasses a broader range of behaviors triggered by fear, which may include flight, freezing, or even submission, in addition to aggression. Therefore, the key aspect of Fight Mode is its focus on confrontation through aggression instead of avoidance.
