A new species of pig-like mammal called a peccary has been discovered in the southeastern Amazon region of Brazil, a scientist announced today. It is the largest peccary in the world, about the size of a large dog.
The newly named beast (Pecari maximus) was found in the basin of the Rio Aripuanã and confirmed to be a distinct species via a genetic analysis conducted by the Leiden Centre for Environmental Sciences in the Netherlands.
Though new to science, locals already knew about the creature. Tupi Indians called it Caitetu Munde, which means "great peccary which lives in pairs."
I think it's funny that the article notes that the local people didn't even realize there was anything strange about the creature, and that they have hunted it for a while now.
This is not the right type of peccary, but it may give you an idea:
