Vaquitas live in an area smaller than ¼ the size of metropolitan Los Angeles. Found only in the upper Gulf of California, Mexico, they are closely related to Southern Hemisphere porpoises. Their ancestors may have crossed the equator during one of the glacial periods between 2.6 million and 11,000 years ago.
