sniffing-butts

According to Scientific American:

“A lot of communication in the animal world occurs via volatile, information-carrying “scent” chemicals, many of which remain to be chemically identified.

Generally speaking, pheromones are a type of infochemical used within a species to influence social behaviors and attract mates whereas kairomones send signals between different species and are often used to detect predators and prey.”

It makes sense that animals would emit and sense different scents interspecies vs. intraspecies, doesn’t it?
