The Vaquita is seldom seen and tends to avoid boats. It is an unobtrusive porpoise, barely disturbing the surface when it comes up to breathe. Despite its general avoidance of humans, they are still in severe decline and will not recover without immediate action taken to save the species. The vaquita most frequently becomes tangled in gill nets meant to catch the totoaba sea bass, which itself is severely endangered. This type of fishing has been declared illegal in the cetacean’s range, but it still occurs and causes harm to the porpoise population.
