Zoarces americanus, commonly known as the ocean pout, inhabits the cold waters of the northwest Atlantic Ocean. It has an elongated body, reaching up to 90 cm, and displays a unique antifreeze protein allowing survival in near-freezing temperatures. The ocean pout is known for its benthic lifestyle, often found among rocky substrates.

Zoarces americanus, commonly known as the ocean pout, is native to the northwest Atlantic Ocean. Its geographical distribution includes the coastal waters of North America, specifically from Labrador in Canada to Delaware Bay in the United States. This species is predominantly found along the Atlantic coast of Canada and the northeastern United States.

The ocean pout inhabits cold, temperate marine environments. It is typically found in shallow coastal waters, often residing in rocky substrates, kelp beds, and eelgrass meadows. These areas provide ample cover and feeding opportunities. The ocean pout is adapted to a wide range of salinities, which allows it to inhabit estuarine environments as well.

Zoarces americanus primarily occupies benthic zones, where it plays a role as both predator and prey. It feeds on a variety of invertebrates, including crustaceans and mollusks, contributing to the ecological balance in its habitat. The species is known for its ability to survive in colder temperatures, which is an adaptation to its native region's climate.
