Scientific Name: Sousa chinensis
Habitat: Tropical and warm temperate coastal waters of Southeast Asia, particularly estuaries and mangroves of Pearl River Delta, Hong Kong, and Taiwan
Diet: Fish, squid (carnivorous)
Threats: Water pollution, coastal development, overfishing, boat traffic
Predators: Sharks
The Chinese White Dolphin (Sousa chinensis) inhabits tropical and warm temperate coastal waters of Southeast Asia, especially in estuaries and mangroves. These dolphins primarily feed on fish and squid, adapting their diet to their coastal environments. Major threats to their survival include water pollution, coastal development, overfishing, boat traffic, and plastic pollution. Natural predators include sharks. They are classified as Vulnerable on the IUCN Red List of Threatened Species, highlighting the need for conservation efforts. These dolphins are also culturally significant, symbolizing marine conservation in their regions (Wikipedia) (世界自然基金會香港分會) (SEAMAP).
The Chinese White Dolphin, scientifically known as Sousa chinensis, inhabits tropical and warm temperate coastal waters of Southeast Asia. They are particularly prevalent in the estuaries and mangroves of regions like the Pearl River Delta, Hong Kong, and Taiwan. These dolphins are coastal and often enter rivers, estuaries, and mangroves (Wikipedia) (SEAMAP).
As carnivorous marine mammals, Chinese White Dolphins primarily feed on nearshore, estuarine, and reef fish, along with cephalopods like squid. They adapt their diet to the availability of prey in their coastal ecosystems (SEAMAP).
Chinese White Dolphins face numerous threats:
Water Pollution: Industrial and urban runoff pollutes their habitats, affecting their health and food sources.
Coastal Development: Urbanization and infrastructure projects encroach on their habitats, leading to habitat loss and fragmentation.
Overfishing: Depletes their primary food sources.
Boat Traffic: Increased maritime traffic poses risks of collisions and disturbances.
Plastic Pollution: Ingesting plastic waste and exposure to pollutants disrupt their health and reproductive systems (Wikipedia) (世界自然基金會香港分會) (SEAMAP).
In their marine ecosystem, Chinese White Dolphins encounter natural predators such as sharks, which pose a threat to their survival (世界自然基金會香港分會).
Due to these ongoing threats, the Chinese White Dolphin is classified as Vulnerable on the IUCN Red List of Threatened Species. Conservation efforts are focused on mitigating pollution, regulating coastal development, and establishing protected marine areas to safeguard their habitats and populations (Wikipedia) (世界自然基金會香港分會).
Beyond their ecological role, Chinese White Dolphins hold cultural significance in regions where they are found, often serving as symbols of marine conservation and environmental awareness. Their presence in estuarine and coastal ecosystems underscores the importance of preserving these critical habitats for biodiversity conservation (世界自然基金會香港分會).
