The totoaba is a large fish native to the northern part of the Gulf of California in Mexico. It can grow up to 2 meters long and is known for its distinctive swim bladder, which is highly valued in traditional Chinese medicine. This fish plays a crucial role in its ecosystem, helping to maintain the balance of marine life. Unfortunately, the totoaba is critically endangered due to overfishing and illegal trade. The demand for its swim bladder has led to severe population declines, prompting conservation efforts to protect this species and its habitat. Efforts include stricter fishing regulations and awareness campaigns to reduce illegal activities.
