Vaquita (Phocoena sinus)

The vaquita is a rare species of porpoise. It is endemic to the northern part of the Gulf of California. Estimates of the number of individuals alive range from 100 to 300. Vaquitas are the smallest and most endangered species of the cetacean.Vaquitas use high-pitched sounds to communicate with one another and for echolocation to navigate through their habitats. They generally seem to feed and swim at a leisurely pace. Vaquitas avoid all boats and are very evasive. They rise to breathe with a slow forward motion and then disappear quickly. This lack of activity at the surface makes them difficult to observe. Vaquitas are usually alone unless they are accompanied by a calf, meaning that they are less social than other dolphin species. Vaquitas are nonselective predators.
