Unlike other fish that live in American waters, the bigmouth buffalo is endemic to the United States. These fish belong to the sucker family, Catostomidae. However, these fish are unique from other suckers in that they filter feed. Their diet is primarily comprised of smaller fish and invertebrates that live on the bottom of the water. These fish lay thousands of eggs during their breeding season which takes place in the late spring and early summer. The average bigmouth buffalo has a lifespan that lasts about a decade. However, the oldest living bigmouth buffalo lived to be over a century old. These fish are edible, and many anglers choose to cook them after capturing them.
