It was estimated in 2007 that only around 150 vaquita remained in the world (4); a number that is declining rapidly as the species is impacted by significant threats (7). The upper Gulf of California is not only home to this Critically Endangered species, it is also the site of intensive commercial and artisanal fishing (7). Vaquitas become entangled in the gill nets and trawl nets that are used in these activities, claiming the lives of an estimated 39 to 84 vaquitas each year (2). This is considered the principal threat to the vaquita's survival (7). The habitat of the vaquita has undoubtedly been changed by the damming of the Colorado River in the United States and the resulting loss of its flow into the Gulf of California; however, the Gulf remains incredibly productive and loss of river input is not believed to be an immediate threat to the vaquita (9).
