The vaquita can be saved from extinction.
Vaquita conservation management and action has been largely ineffective at controlling vaquita mortality in gillnets.
At the current rate of decline, the vaquita could be extinct by 2018.
Vaquitas have probably always been rare.
Highly-trained US Navy bomb-locating bottlenose dolphins are being used to locate vaquitas.
The oldest vaquita was estimated to be 21 years of age.
As well as gillnet entanglement, the vaquita is vulnerable to several other potential threats.
Mortality in gillnets has long been recognized as the most serious and immediate threat to the vaquita’s survival.
The vaquita and the totoaba, a large long-lived fish species in the croaker family, have much in common.
The demand for dried totoaba swim bladders is threatening not just the totoaba but also the vaquita.
There are less than 30 vaquita individuals left in the wild.
The vaquita’s population is declining rapidly, with a decline of nearly 50% since 2015.
Most biological and ecological information of the vaquita is unkown.
The mating system and social structure of the vaquita have not been studied.
The vaquita is the only cetacean endemic to Mexico.
Vaquitas are generalist feeders, consuming a wide variety of over 21 benthic and demersal (bottom-dwelling) teleost fish, squids, and crustaceans.
Vaquita are typically inconspicuous at the surface as they avoid boats and rarely splash, jump, or leap.
Unlike most other porpoise species which breed every year, vaquitas give birth every 2 years.
Potential predators of vaquitas are large sharks, killer whales, and man.
There is reverse sexual dimorphism in the vaquita, as females are larger than males.
Vaquitas usually occur in small groups of 1-3 individuals; often just a mother and calf pair.
The life span of the vaquita is expected to be similar to that of the harbor porpoise, approximately 20 years.
The vaquita was not scientifically described until 1958, with full descriptions of external morphology not available until 1987.
The vaquita is the most endangered marine cetacean in the world.
The vaquita has the smallest geographical range of any marine mammal.
The vaquita is the smallest porpoise species.
The vaquita is a marine species that lives in a relatively shallow, turbid, and dynamic environment, typically less than 40 meters deep.
The vaquita’s name “sinus” is Latin, meaning “bay,” referring to the occurrence of the species in the Gulf of California.
Fishermen in the upper Gulf of California were familiar with the vaquita long before scientists were aware of its existence.
The vaquita first became known to the scientific community after the discovery of a bleached skull in 1950.
