Monkey World sent one animal to Twycross, a female that has since died, at what must have been a fairly young age. Not sure how many animals Twycross sent them before the two recent males, didn't they get most of theirs from Apenheul, apart from the recent acquisitions.
I remember an old episode of Monkey Business (or whatever it used to be called) where they sent a monkey to Twycross, it must've been this individual.
A shame that they've gone though, they were a very charismatic species!
