What herbivores live in the rainforest?
This is a tough question to answer because there are multiple different types of rainforests. A rainforest in the typical sense is a tropical forest that receives at least 100 inches of rainfall a year, but there are also temperate rainforests which receive about 79 inches of rain per year. The image below is of a temperate rainforest.
Rainforests are diverse and exist on multiple continents. Thus, different herbivores inhabit different rainforests. Here's a map of rainforests of the world below:
Howler monkeys in Central and South America are herbivores, as are capybaras, leaf-cutter ants, sloths, and many, many other insects, birds, and mammals.

All were filmed in Peru in 2011 - Tambopata River.
In South East Asian rainforests, you have gibbons, rhinos, elephants, and, again, many more animals.
