There's only one remaining population of Baudin pigs left in the world, but now two more of these extremely rare pigs have died on South Australia's Kangaroo Island.
The Baudin pigs were released onto the island by French explorers in the early 1800s and have since developed into a unique strain.
But a bushfire decimated the wild population in 2007.
Owner of the last remaining population of these pigs, William Marshall, says the recent loss of an additional two pigs, to natural causes, drags their numbers down to 11.
"It leaves me with three mature boars, two sows that haven't bred, two breeding sows which are breeding and four very young, seven or eight week old little female piglets that I've hand raised from one of these younger breeding sows, but just such precarious numbers being the last of them in the world."
