Well, in fact, those are peccaries, not pigs. I've checked the difference out and... well, they are no doubt important if you're zoologist. They include important facts like different teeth, more complex stomach and fact they are more aggressive then pigs (that could be important for nonzoologists too, but since a wild swine is just as able to give you a chase when it has piglets, the difference isn't really all that big).
Anyway, this little, I think the guys are cute, so whether they are piglets or peccarilets, I like them.
Some (real) pigs:
