Here we have a male and female lion (Pantheraleo) in the middle of quite the communication. Lions have one of the most complex behaviors of any felines as they are a very social creature. When resting, lion socialization occurs through a number of behaviors, the most peaceful being head rubbing and social licking. They also communicate through a variety of calls each with a different volume, intensity, tone and tempo. Their communications include snarling, hissing, coughing, meowing, purring and of course, roaring – the loudest roar of any large cat.
