Evidence suggests that catfish are opportunistic feeders and may be the least gape limited of North American freshwater predatos. To better understand the size of prey vulnerable to catfish look at gape dimensions for individuals of various sizes to determine the maximum size prey a catfish can kill based on its gape limitations. I believe results support the assumption that catfish are one of the least gape-limited predators.
Eric, can you expand on this, please? How can a predatory fish be non-gape limited, i.e. how do I eat a cheeseburger taller than my mouth at maximum opening in a single bite?
