"dogfish" 的定义和意义

What is a "dogfish"?

A dogfish is a small to medium-sized shark found in various parts of the world's oceans. They have slender bodies, typically gray or brown in color, and are known for their sharp teeth and streamlined shape. Dogfish are opportunistic predators, feeding on a wide range of prey including fish, squid, and crustaceans. They are well-adapted to their marine environment, with a keen sense of smell and excellent maneuverability. While some species of dogfish are commercially important for their meat and oil, others are considered bycatch in fisheries. Despite their name, dogfish are not closely related to dogs and should not be confused with domesticated animals. They play a crucial role in the marine ecosystem, contributing to the balance of marine food chains.
