Is it a moose or an elk in the picture attached? It's from this Wikipedia article. I've always called this animal an elk. Wiki says:
The moose (North America) or elk (Eurasia), Alces alces, is the largest extant species in the deer family.
So these two words are synonyms.
On the other hand, Encyclopaedia Britannica gives the following information:
*Elk (Cervus elaphus canadensis), also called wapiti, the largest and most advanced subspecies of red deer (Cervus elaphus), found in North America and in high mountains of Central Asia.
Moose (Alces alces), the largest member of the deer family Cervidae (order Artiodactyla).*
As you see, these are two different species, the moose and the wapiti (or the American elk).
What is the animal in the picture called?
