There are many subspecies of wolf including the Arctic wolf, all of which use a variety of howls to communicate to one another.
Wolves are legendary because of their spine-tingling howl, which they use to communicate. A lone wolf howls to attract the attention of his pack, while communal howls may send territorial messages from one pack to another. Some howls are confrontational. Calls may be answered by rival packs. Much like barking domestic dogs, wolves may simply begin howling because a nearby wolf has already begun.
Lions communicate through a range of behaviours and their expressive movements are very highly developed. They will perform peaceful tactile actions such as licking each other and rubbing heads. Head rubbing, or nuzzling, is a common greeting behaviour for lions. They also communicate through a variety of vocalisations including purrs, snarls, miaws and hissing. Their vocalisations also vary in intensity and pitch.
Lions roar to communicate their position to other prides. A lion’s roar is the loudest of any big cat and can be heard up to 8 km away.
