Beluga is a very lovely whale, they are very friendly to humans. They are also very active whales, like activities, will be a variety of tools as their own toys to play. Moreover, they like to interact with humans, and kissing is one of the manifestations of interaction. Belugas can be kissed because they are friendly and do not harm humans. However, a human kiss may be harmful to belugas, especially if humans wear lipstick. Not only human kissing, human touching and other actions may cause damage to belugas, leading to their reduced life span, so it is recommended not to kiss them, do not touch them, can carry out other harmless interaction activities.
As mentioned above, belugas prefer to kiss humans because they are more friendly to humans. And in some aquariums, it is common to see belugas kissing humans. Some biologists have found that belugas may be close to humans because they think humans are more like their babies, so they do a lot of close activities. However, belugas themselves do not understand that human kissing and touching are harmful to themselves, so we had better not do similar behavior when we go to see belugas to avoid causing harm to them and affecting their life span.
