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)

It's technically an oversimplification since Argentinian owl monkeys, A. a. azarae, are cathemeral (active both day and night). http://pin.primate.wisc.edu/factsheets/entry/owl_monkey Jcblackmon (talk) 00:46, 9 August 2008 (UTC)

Do you know if that applies to the species Aotus azarae in general or just the subspecies A. a. azarae? Rlendog (talk) 03:18, 9 August 2008 (UTC)

Just the subspecies. - UtherSRG (talk) 09:51, 9 August 2008 (UTC)

extinct species Insulacebus toussaintiana

I'm going to update the taxobox on Insulacebus to have the genus be in family Aotidae. I plan to also update this page to have a small amount of info on that species. Should be similar to the info at titi or Cebidae, as a couple of examples. - UtherSRG (talk) 23:29, 11 September 2022 (UTC)

I was wrong about this. See below... - UtherSRG (talk) 20:22, 12 September 2022 (UTC)
