Gaper (fish)
A "gaper" is a common name applied to several species of fish, often referring to those with mouths that can open very widely, creating a "gaping" appearance. The term is not a precise taxonomic descriptor and can vary regionally in its application.
In North America, the name "gaper" is most frequently associated with the Chilara taylori, a species of eelpout found along the Pacific coast. These fish are elongated and possess a large mouth, hence the name.
In other regions, different species with similar characteristics may be locally referred to as "gapers." The specific fish species considered a "gaper" can depend on local fishing practices and common names.
