红蟹, also known as the red crab, is a species of crab found primarily in the South China Sea and along the coasts of Southeast Asia. They are characterized by their vibrant red color and are often sought after for their sweet, tender meat. These crabs typically inhabit rocky shorelines and coral reefs, where they feed on algae and small marine organisms. The red crab is an important part of local fisheries and is often featured in various culinary dishes. Due to their popularity, sustainable fishing practices are encouraged to ensure their populations remain healthy. Conservation efforts are also in place to protect their natural habitats from pollution and overfishing.
