Pygmy Marmoset X Geoffroy's Marmoset

I believe this is the hybrid between Cebuella pygmaea and Callithrix geoffroyi free-roaming in the Jungle House.

A full species list of the walkthrough jungle house this individual is housed in is the following;
White-faced saki
Pygmy marmoset
Pygmy marmoset x Geoffroy's marmoset (unsigned)
Linnaeus' two-toed sloth
Ground cuscus
Northern sugar glider (unsigned)
Northern treeshrew
Grey-legged night monkey
Seba's short-tailed bat
Rodriguez flying fox
Tokay gecko (unsigned)
Chinese water dragon
Green iguana
Argus pheasant
Little owl

@Vision saw this individual today, very odd looking. Can I confirm you've labelled this as father x mother?

@Javan Rhino, I don't know for certain what the parents' genders were, sorry. :/
This was how the volunteer present said they were listed on the inventory list, though.

Thanks @Vision, if it wasn't for this photo I wouldn't have even given it a second thought, but very interesting looking animal
