"Open-backed fish" usually refers to the sunfish (Lophius piscatorius), also known as deep-sea angler fish, sea cockroach fish, cockroach fish, dragon fish, etc. The openback is not a type of fish, but a common name that refers to a type of deep-sea fish. The following is a detailed introduction to this species of sunfish:
Physical characteristics: The sunfish has a wide, flat body, a wide head, a large mouth with retractable jaws, and a flat body dorsally and ventrally. The body is usually covered with hard scales, which come in a variety of colors, often showing a natural undertone to suit the underwater environment.
Characteristic organs: Its most distinctive feature is the dorsal spinal spine (commonly known as the "ghost claw"), which is a dorsal fin supporting bone extending at the front of its head, similar to a "rod" used to capture prey.
Habitat environment: Sunfish usually lives in deep sea environments, mainly inhabiting continental slopes and continental shelf edges. The depth can reach about 1,000 meters. It is a typical deep-sea bottom fish.
Predating habits: Sunfish usually camouflage themselves to become part of the seafloor environment, waiting for prey to pass by and quickly prey on it. Its unique appearance and feeding habits make it an important member of the marine ecosystem.
Economic value: Sunfish is considered a deep-sea fishery resource with important economic value. Its meat is rich in texture, showing a tender and delicious taste. It is favored in some areas for its high protein and low fat nutritional value.
Cooking methods: Sunfish is often used in a variety of dishes. Cooking methods such as frying, roasting, boiling and stewing are all very popular.
In view of the fact that fishery development of deep-sea fishes can easily have certain impacts on them, in some areas, deep-sea fish resources, including sunfish, are being strictly protected to ensure their health and balance in the marine ecosystem.
All in all, sunfish is a deep-sea bottom fish that has attracted much attention for its unique appearance, deep-sea ecological status and edible value. At the same time, it also needs reasonable protection and management to ensure its survival and reproduction in the future.
