don't all carnivores?

Strictly speaking the spider monkey is an insectivore, a group not known for their counting ability. That ability is unique to primate insectivores.

arachnivore, in reality :p

1 in 10000 suffer arachnaphobia

How does one tell the difference between arachnophobic spider monkey and an anorectic one?

Do you have a source for this information, or is the comic only for entertainment, rather than edutainment?
