Are these Ivory carvings real?

Question:

Are these Ivory carvings real?

How can I tell if they are real or not. The price is very cheap. They measure 26 inches. Thanks!

I'm not going to buy the statues because I'm against the killing of elephants. The question is for a friend who wants to buy it and resell it. Thank you for your answers!
