The Genus Psephurus, commonly known as the Chinese paddlefish, is a critically endangered species of freshwater fish found in China's Yangtze River. Due to overfishing, pollution, and habitat loss, the species is at risk of becoming extinct. Synonyms for this genus include Psephurus gladius, Paddlefish gladius, and Chinese sword fish. Their unique elongated snout adapted for filter-feeding make them distinct from other fish species. Conservation efforts are currently underway to protect this iconic species and prevent their disappearance from our planet. As apex predators, they play a crucial role in maintaining the ecological balance in the river system.
