According to rough estimates, with the vaquita population falling by 40% a year, and only 60 alive a year ago, there could be as few as three dozen left. Even though it has never been targeted directly by hunters (like many of the large whales and dolphins), accidental capture in net fisheries is a significant threat to continued survival of the vaquita as a species.

Overall (100 \% of samples analyzed), individual PAHs and the dispersant component dioctyl sodium sulfosuccinate were found in low concentrations or below the limits of quantitation using analytical chemical methods. Experts including Rojas-Bracho; Barbara Taylor, leader of Marine Mammal Genetics Program at the National Oceanic and Atmospheric Administration; and Sarah Mesnick of the NOAAs Southwest Fisheries Science Center, emphasized that the capture program should not divert effort and resources away from extension and enforcement of the gillnet ban, which remains the highest-priority conservation actions for the species.

This phenomenon is attributed to the anthropogenic Allee effect, specifically on the end where small population size leads to low species fitness because of a lack of genetic diversity and the potential for inbreeding. So much so, that can be sighted from afar, simply from the froth they produce from frequent breaches. Only adolescents perform full breaches out of the water. There are no porpoises of the cetacean phocoenid family in the Gulf.

Porpoises, on the other hand, have much smaller mouths and spade-shaped teeth. This effort, called VaquitaCPR,[51] captured two vaquitas in 2017: One was later released and the other died shortly after capture after both suffered from shock. "[49] A back market for totaba swim bladders has developed fairly recently in China (including Hong Kong). Lorenzo Rojas-Bracho, the chairman of the International Committee for the Recovery of the Vaquita, wrote that an international group of experts, including navy personnel, have been working on two primary goals: determining the feasibility of locating and catching vaquitas, as a phase one. During the NOAA testing programs existence, sensory and chemical testing methods were used to measure polycyclic aromatic hydrocarbons (PAH) and dispersants in more than 8,000 seafood specimens collected in federal waters of the Gulf of Mexico.

Bottlenose dolphins from the 1987 to 1988 epizootic were shown to be infected with either DMV or PMV, while only PMV was identified in the later Gulf of Mexico epizootic by gene sequence analysis (Taubenberger et al., 1996). The orca, otherwise known as the killer whale, is actually not a whale at all, but the largest dolphin species in the dolphin family! There are multiple ways that dolphins could have been exposed to the oilthey might have inhaled vapors at the waters surface, incidentally ingested oil from sediments or water while feeding, or have been exposed by eating whole fish, including internal organs and fluids such as liver and bile, which can harbor chemical contaminants. Experts estimate there are 30 vaquita porpoises remaining, and all of them live exclusively in the waters of the Gulf of California.
