Love in the animal kingdom can be displayed through physical and verbal communication. Animals pass information between each other with signals, which are cues that can be picked up by the sensory system and are transmitted from one animal to another. Sounds, songs, scents, and waving a hand/paw/claw (body language) are all examples of signals. It can be tricky for some. Males will put on a show, sing and dance, or compete to the death for the favor of a female. Some species only have brief liaisons while others have lifetime bonds and partnerships. Meanwhile, what they all have in common is at the end of the courtship; the decision mostly comes down to the female.
We will first look at the elephants. Since elephants are highly intelligent, they are fascinating to watch when it comes to how they communicate. They use a combination of both verbal and non-verbal methods to convey messages. "When males want to attract females they can offer very high pitched trumpeting sounds for many hours throughout the day. This will continue in order to attract females. It is believed that this can actually put a female into estrus which will make them give off powerful hormones and want to mate with the males that are calling out there" (Elephant Communication). When it comes to an elephant's non-verbal communication, when they come into contact with those they know, they often wrap their trunks around each other. This is a sign of excitement and affection, similar to how humans give each other a hug or even shaking hands. Also, elephants can be seen rubbing their bodies against each other as a sign of affection.
Another species in the animal kingdom that has an interesting love language is horses. "If you get a chance to see them in the wild they are mutually grooming each other, scratching each other, leaning gently into each other, sharing breath with each other (a very intimate activity done by putting their noses together and sharing the air).
