Aliens In Hong Kong

Believe it or not? Aliens are everywhere in Hong Kong. There must be some around you. Of course, I am talking about alien species – the species introduced outside their original distributions. From house cockroaches, apple snails, fire ants, to vertebrate as below. These are all not native to Hong Kong.

Whether if the Water monitor (Varanus salvator) is a native or introduced species is not confirmed. But many believe it is an introduced species.
