A long, concrete block of primate cages combined with a pile of rocks on a monkey island. Hmmm, are these exhibits ancient? I've actually heard that the Frankfurt Zoo has an impressive collection of primates.
Night Monkey
Slender lori
Moholi Galago
Aye-Aye
White Faced saki
Emperor Tamarin
Golden lion tamarin
Goeldi Tamarin
Pygmy marmoset
Fat tailed dwarf lemur
grey mouse lemur
( Both species together with Aye-aye)
The golden times of the primate collection are gone, so the zoo has had red uakaris,douc langurs,proboscis monkeys,spectacled langurs, sanisbar colobus, red holwer monkeys,hanuman langurs, patas monkeys,dwarf guenons,siamangs,diana monkeys,mandrills to name just a few. They are all gone since the seventy years, a few of them dissapared in the last 10 years.
