Vaquita
Why in News: The world’s most endangered marine mammal, the vaquita, is teetering on the edge of extinction.
About Vaquita
The vaquita, scientifically known as Phocoena sinus, is the smallest member of the porpoise family and is known for its shy nature.
Endangered Status
- Vaquitas are the most critically endangered marine mammals globally, with fewer than 20 individuals remaining in the wild.
Distribution
- They inhabit the northern part of the Gulf of California, where the waters are abundant with fish and shrimp.
- Vaquitas are typically found in shallow waters up to 50 meters deep.
Physical Features
- Vaquitas are the smallest cetaceans, measuring between 4 to 5 feet (1.2 to 1.5 meters) in length and weighing 65 to 120 pounds (29.5 to 54.4 kg).
- They have chunky bodies, rounded heads without snouts, and sport a dark gray coloration with lighter gray undersides and distinctive black patches on their face.
- Their dorsal fins are unusually tall and wide compared to other porpoises, and they feature a dark ring around their eyes.
Behavior
- Known for their elusive behavior, vaquitas tend to avoid boats and human activity.
- They use echolocation, emitting high-frequency clicks for communication and navigation underwater.
Threats
- The decline in vaquita numbers is primarily attributed to illegal gillnets set for totoaba, a large fish endemic to the Gulf of California.
- Both vaquitas and totoabas are similar in size, making them unintentional victims of these gillnets.
Conservation Status
- Vaquitas are classified as Critically Endangered on the IUCN Red List, highlighting the urgent need for conservation efforts to protect this species.
