Which type of pheromones helps in recognizing other animals?

Territorial pheromones play a crucial role in recognizing and establishing boundaries among animals. These pheromones are secreted by animals to communicate to others that an area is claimed and to deter intruders from entering their territory. This recognition allows animals to maintain social order and minimizes conflicts over space. By marking their territory with specific scents, they communicate their identity and status to other animals, facilitating awareness and recognition within their species.

In this context, it is essential to understand that other types of pheromones serve different functions. For example, alarm pheromones are used to signal danger and elicit a flight response, while aggregation pheromones attract individuals to a common location without necessarily conveying information about boundaries. Similarly, epideictic pheromones can provide cues about population density but do not specifically facilitate territorial recognition. Therefore, the function of territorial pheromones as identifiers of space and owners makes them the correct choice for recognizing other animals.
