Are all spiders predators? They are, aren't they? Why am I asking you when I can just ask google? Google says yes, all spiders are predators. It's weird to me that in the entire evolutionary history of the spider, some 380 million years, not a single spider decided to go vegetarian. Maybe one did but then it got eaten by another spider. Anyways, I found some interesting pictures of fossil spiders with these weird giraffe necks in a book, and it turns out that there are living examples! Crazy.
Did you know there were once predatory ungulates? That's right, hoofed carnivores. Like vampire cows only meaner. Andrewsarchus mongoliensis is a great example.
And did you see this bird-poo caterpillar? Not many predators for those things, I'll bet.
