An article on ChaCha shows a list of animals you never knew existed. Two of them are "types" of Pigs!
First the Sea Pig - Sea Pigs live in nearly every ocean except for the North Atlantic and
East Pacific. They have tentacles that are used to shovel dead organic
matter into their mouths. YUM.
More about the other bizare creature inside the artile.
Second is the completely bizare Pig-Butt Worm. If it makes you feel any better, the scientific name is pugaporcinus,
which basically translates to "having the likeness of a pig rump."
This is truly some weird shit.
