Chinese Paddlefish
The Chinese Paddlefish, now critically endangered, once thrived in the Yangtze River. It is distinguished by its long, paddle-like snout and can grow up to 23 feet. This fish is elusive due to drastic population declines from habitat destruction and overfishing. Unexplored stretches of the Yangtze hold the last hopes for its survival. Efforts to locate and protect any remaining individuals are ongoing.
Alligator Gar
The Alligator Gar is native to the rivers of the southeastern United States, particularly the Mississippi River Basin. It can grow up to 10 feet long and is recognized for its elongated body and gator-like snout. Elusive due to its nocturnal habits and preference for deep waters. It is one of the oldest fish species, with fossils dating back over 100 million years. Its resilience and ancient lineage make it a fascinating subject of study.
