Primate brain has special parts specifically wired to visually process snakes [1]. It is also thought that it has specific parts that process the shape of spider, and maybe other insects [2]. This is one explanation why primates have such a strangely large brain. Processing image requires a lot of computational power, being arboreal, primates need to distinguish snakes and spiders to safely crawl in the forest. This is not to say, primates wouldn't eat snakes or spiders. I don't know if other primates eat them (they might be?) but humans do eat both [3] [4].
