Kampung children are familiar with the sparring behaviour between the males of the Fighting Spider, Thiania bhamoensis . Spiders are territorial animals who prefer to live by themselves individually. Rarely do they interact with their own kind except when mating.
Spiders do fight when they meet.
Kissing is associated more with the human behaviour and do not exist in the animal kingdom. Insects, like the ant, may appear like kissing when they meet but they are communicating by 'knocking' their antenna. These fishes can be found in many tropical fish aquariums.
