Greenling

Greenling is a common name that can refer to several different species of fish, primarily within the family Hexagrammidae. The most widely recognized greenling is the kelp greenling (Hexagrammos stellaris). These fish are found in the North Pacific Ocean, inhabiting rocky reefs and kelp forests from Alaska down to California. They are typically greenish-brown to olive in color, often with spots or bars, and can grow up to about 30 inches in length. Kelp greenling are omnivorous, feeding on a variety of small invertebrates, algae, and smaller fish. They are an important part of the nearshore marine ecosystem.

Another species sometimes referred to as greenling is the lingcod (Ophiodon elongatus), although this is less common and can cause confusion. Lingcod are larger predatory fish, also found in the North Pacific, and are known for their mottled brown and green coloration. However, they belong to a different family, Ophiodontidae. The term "greenling" most accurately describes members of the Hexagrammidae family, such as the kelp greenling and the masked greenling (pleurogrammus arizonae). These fish are often caught by recreational anglers and are considered a food fish in some regions, though their populations can be affected by fishing pressure and habitat degradation.
