Talk:Night monkey
From Wikipedia, the free encyclopedia
[edit] Color vision?
Quote:
- Unusually among the New World monkeys, they are monochromats, that is, they have no colour vision [...]
Interestingly, the corresponding entry in the German Wikipedia claims that Night monkeys do have color vision and that this shows that they are descended from diurnal ancestors. What's up with this? --Naddy 14:27, 17 Sep 2004 (UTC)
Quote:
- They are called night monkeys because they are active at night and are in fact the only truly nocturnal monkeys.[...]
This needs a reference.--joeyo 15:24, 26 June 2006 (UTC)
