Are there any pairs of species that act as each other's primary predators (or prey)?
This question occurred to me the other day, and it's been bugging me since then. I realize the energy dynamics don't really work out if they are both each other's only primary food source, but are there any pairs of animal species that prey on each other to the extent that both species could be considered both predator and prey?
