Schooling Edit
Like other Phocoena, vaquitas are usually seen by themselves. If they are seen together, it is usually in small groups of two or three individuals.[6] Less often, groups around 10 have been observed, with the most ever seen at once being 40 individuals.
Diet Edit
Vaquitas tend to forage near lagoons.[6] All of the 17 fish species found in vaquita stomachs can be classified as demersal and or benthic species inhabiting relatively shallow water in the upper Gulf of California. Vaquitas appear to be rather nonselective feeders on small fish and squid in this area. Some of the most common prey are teleosts (fish with bony skeletons) such as grunts, croakers, and sea trout.[13] Like other cetaceans, vaquitas may use echolocation to locate prey. They possibly locate their prey by following the sounds of prey movement.[1]
