Bathymasteridae
The Bathymasteridae are a family of marine ray-finned fishes, the ronquils, belonging to the order Scorpaeniformes. They are found in the northern Pacific Ocean, primarily along the coasts of North America and Asia. Ronquils are generally small, bottom-dwelling fish that inhabit a variety of habitats, including rocky reefs, sand flats, and muddy bottoms.
Common Names
Members of this family are commonly known as ronquils. Other common names include sandfish, flatheads, and lingcod, although the latter name is more often used for a different species.
Characteristics
Ronquils are characterized by their elongated, flattened bodies, which are often covered in scales. They have large, protruding eyes and small, terminal mouths. Their dorsal fin is long and continuous, with a distinct anterior portion that is often spiny. Ronquils typically have a single anal fin, a pair of pelvic fins, and a forked caudal fin.
The coloration of ronquils varies depending on the species, but many are drab brown or gray with darker markings. Some species have bright orange or yellow fins. Ronquils can grow to a maximum length of around 30 centimeters (12 inches), but most species are much smaller.
Environments
Ronquils are generally bottom-dwelling fish that inhabit a variety of habitats, including:
- Rocky reefs
- Sand flats
- Muddy bottoms
They are often found in shallow water, but some species can live at depths of up to 1,000 meters (3,300 feet). Ronquils are carnivorous and feed primarily on small invertebrates, such as worms, crustaceans, and mollusks. Some species may also consume small fish.
