Veterinarians would evaluate vaquitas reactions and release stressed individuals, they wrote. Their ancestors are thought to have moved north across the equator more than 2.5 million years ago during a period of cooling in the Pleistocene. At the current rate of loss, the vaquita will likely decline to extinction by 2022 unless the current gillnet ban is maintained and effectively enforced, Rojas-Bracho wrote.

Dolphins and porpoises are closely-related species, which is why they have notable similarities. However, porpoises require much shallower water, and they enjoy both freshwater and saltwater. Mem. The main difference between these two marine mammals is most noticeable in their faces, fins, and body shapes. For example, Louisiana has closed areas of the Barataria Bay Basin.

Unlike a lot of other dolphins, the Frasers dolphin mostly stays away from boats. Necessary action includes habitat protection, resource management, education, fisheries enforcement, alternative livelihoods for fishermen, and raising awareness of the vaquita and associated issues.

New Jersey is the farthest north theyve been seen. 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. One way scientists tend to differentiate these creatures is by their habitats. [6], The genus Phocoena comprises four species of porpoise, most of which inhabit coastal waters (the spectacled porpoise is more oceanic).
