in terms of pets, dog is undoubhtly most popular. talking about wild animals, india is a biodiversity hotspot so there are a lots and lots of popular animals among animal gazers but i think lion which is national animal, is most popular.
Animals are multi-cellular, they can move on their own, and are heterotrophs. most of the animals have furs which is the most common characteristic. Also, they are eukaryotic and they sexually reproduce.
It would be your own personal opinion. The most popular animal in North America to hunt is the Whitetail deer. For me it is Dangerous Game in Africa. It is my complete passion and when I get older I want to be a P.H. in Africa.
