What is elk and emu?

Answer 1

"A deer is a ruminant mammal belonging to the family Cervidae. A number of broadly similar animals, from related families within the order Artiodactyla, are often also called deer."

The above answer is from Wikipedia. Deer family animals have split hoofs, equine family have a single hoof. Deer are more closely related to goats, sheep and cows than to horses not only due to the feet, but due to their digestive system.

Answer 2

Emus and ostriches are both large, long-necked, Flightless Birds with excellent vision. They belong to the same order of birds - ratites - but are not in the same family. Other ratites include the Southern cassowary of Australia and New Guinea, the kiwi from New Zealand, the ostrich from Africa and the rhea from South America.

Ratites have wings but the bones in their chests do not have the capacity for flight muscles, which is what a bird needs to fly.

Answer 3

An elk is a large species of deer. An emu is a large species of bird.
