A Field of Spines

I always wonder how plants with so many spines can grow so close together. When people become prickly, we usually keep our distance. These cactus seem to thrive by being jammed together like they were on a Japanese subway. Of course, this kind of crowding provides each individual plant with protection. But my question is protection from what? Would you eat a cactus? Actually, people do eat cactus all the time. Not this particular species, but there are edible cactus. I also see cactus that get eaten by all sorts of desert animals. Maybe there is protection and strength in numbers.
