flying squirrels and sugar gliders are similar in terms of their size, fur, big eyes, white belly and capability to glide from treetops using a thin piece of skin that is stretched between their legs. nevertheless, they differ in locations since sugar gliders live in australia and flying squirrels live in north america and sugar gliders are marsupial mammals and flying squirrels are placental mammals.   biologists have figured out that sugar gliders and flying squirrels are probably not very closely related as the result in studying their genes and other traits. so in this case, if flying squirrels were brought to australia, probably, they’d compete with sugar gliders for resources.
