Vaquita (Phocoena sinus)

The vaquita, scientifically known as Phocoena sinus, is a species of porpoise and is considered the most endangered marine mammal in the world. This elusive cetacean is endemic to the northern part of the Gulf of California, located in Baja California, Mexico.

Physical Characteristics

The vaquita is the smallest species of the cetacean family, characterized by its diminutive size, with adults measuring about 1.4 meters (4 feet 7 inches) in length and weighing approximately 54 kilograms (119 pounds). Its distinctive facial markings, including a dark ring around the eyes and dark patches on the lips, distinguish it from other porpoises. The vaquita’s body is robust with a rounded head and lacks any prominent rostrum.

Habitat and Distribution

Confined to the northern reaches of the Gulf of California, the vaquita's habitat is limited to a small area, making it particularly vulnerable. This region, known for its rich biodiversity, is a critical habitat for various marine species, yet it is not without its threats.

Conservation Status

The vaquita is classified as critically endangered by the International Union for Conservation of Nature (IUCN). Its population has been severely reduced due to several factors, the most significant being bycatch in illegal gillnets used for fishing totoaba, a large fish also native to the Gulf of California. The swim bladder of the totoaba is highly valued in traditional medicine, leading to illegal fishing practices that inadvertently capture and kill vaquitas.

Efforts in Conservation

Various conservation efforts are underway to protect the remaining vaquita population. Organizations and government bodies are working to enforce fishing bans and remove illegal fishing nets from the vaquita's habitat. There is also a push for sustainable fishing practices and increased awareness about the vaquita's plight.
