Behavior Edit
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.[8] Vaquitas are usually alone unless they are accompanied by a calf,[9] meaning they are less social than other dolphin species. They may also be more competitive during mating season.[10] They are the only species belonging to the porpoise family that live in warm waters.[11] Vaquitas are nonselective predators.[12]
