Moridae
The Moridae, commonly known as codlings, are a family of cod-like fish found in the cold, deep waters of the Atlantic, Indian, and Pacific Oceans. They are characterized by their elongated bodies, small mouths, and barbels, which are whisker-like sensory appendages located under their chins. Moridae are generally bottom-dwelling fish, often inhabiting depths of 200 to 1,000 meters (660 to 3,300 feet), where they feed on crustaceans, polychaetes, and other small invertebrates.
Common Names
Moridae are known by a variety of common names, including codlings, grenadiers, rattails, and cusk-eels. These names reflect the diverse appearance and habits of the various species within the family.
Characteristics
Members of the Moridae family share a number of distinctive characteristics, including:
- Elongated, cylindrical bodies
- Small, terminal mouths
- One or two barbels under the chin
- Two dorsal fins, the first of which is short and spiny
- One anal fin
- A forked caudal fin
- A lateral line that runs along the sides of the body
- Scales that are small and embedded in the skin
Moridae species vary in size, with some reaching lengths of over 2 meters (6.5 feet). They are generally silvery or grayish in color, and their bodies are often covered in small, black spots.
Environments
Moridae are primarily found in cold, deep waters, inhabiting the continental slopes and abyssal plains of the Atlantic, Indian, and Pacific Oceans. They are often associated with seamounts, canyons, and other topographic features that provide suitable habitat. Their diet consists mainly of benthic invertebrates, such as crustaceans, polychaetes, and other small organisms. Moridae are an important part of the deep-sea ecosystem, serving as prey for larger fish and marine mammals.
