Esox

Esox is a genus of freshwater predatory fishes, including northern pike, muskellunge, and several species known as pickerel.

Esocidae: Esocidae is the family of ray-finned fishes that includes the genus Esox. Esox is the family’s living genus of pikes and related fishes.
Ambush predator: An ambush predator captures prey by waiting or hiding before making a sudden attack. Esox typically strikes from cover rather than pursuing prey over long distances.
Pike fishing: Pike fishing is recreational or commercial angling directed at pike species. Anglers target Esox with methods adapted to their teeth and ambush behavior.
Perch: Perch are spiny-finned fishes in the family Percidae, including many freshwater species. Perch are common prey and ecological competitors, but belong to a different fish lineage.
Esociformes: Esociformes is an order of ray-finned fishes that includes Esocidae and its relatives. This broader classification places pikes among their closest fish lineages.
Lateral line: The lateral line is a sensory system that detects water movement and pressure changes in fishes. It helps pike locate disturbances caused by nearby prey.
Catch and release: Catch and release is a fishing practice in which captured fish are returned to the water. It is commonly used in recreational fisheries for large pike and muskellunge.
Walleye: The walleye is a predatory freshwater fish in the perch family, Percidae. Walleye share habitats with pike but have a different body plan and ancestry.
Ray-finned fish: Ray-finned fishes are vertebrates whose fins are supported by bony or cartilaginous rays. Esox belongs to this vast group of bony fishes.
Fish jaw: A fish jaw is a skeletal structure that supports the mouth and helps seize or process food. Pike jaws carry backward-pointing teeth suited to holding slippery prey.
