What type of behavior is exhibited by an animal that growls, hisses, bares teeth, and lunges?

1. Curious

2. Playful

3. Defensive

4. Threatening

The correct answer is: Threatening

The behavior exhibited by an animal that growls, hisses, bares its teeth, and lunges is indicative of a threatening response. This type of behavior typically signifies that the animal feels threatened or is warning a potential aggressor to stay away. Such actions are often associated with a desire to confront or deter perceived danger, reflecting the animal's instinctual need to protect itself or its territory. When an animal growls or hisses, it produces vocalizations that signal discomfort or aggression, while baring its teeth can be a clear indication of a willingness to bite if the situation escalates. The lunging aspect of the behavior adds an element of intimidation, suggesting an intention to scare off an intruder. This combination of actions is a common way for animals to communicate their readiness to defend themselves, making it primarily a display of threat rather than other types of behaviors like curiosity, playfulness, or defensiveness. In contexts where the animal feels cornered or overly challenged, it might also show this kind of aggressive behavior as a first line of defense.
