Ambush predators evolve large weapons because they strike rather than chase prey

Evidence

Weapons in ambush predators experience very different selection from weapons in other predators. Instead of running, swimming, or flying fast to catch prey, ambush predators snatch them with a quick strike from claspers. As a result, many have large weapons. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 956
