Sus barbatus barbatus. One of the species I was looking most to see, Zoo Berlin holds two of these odd pigs in the Suid House; though I've only seen one individual during my visit. Considering the European population is quite old and inbred, this might be the last time I see this species in Europe but I dearly hope not!
Just checked Zootierliste again and it seems that since 2016, Berlin Zoo only keeps 1 individual (the one I've seen) and considering the fact London only has 3 individuals left including 1 castrated male (to avoid inbreeding, considering this species is knowing a real bottleneck there), it is now sure the species is doomed unless Europe imports new individuals..
