How many species of vaquitas exist?
There is only one recognized species of vaquita: the Phocoena sinus. Vaquitas are a unique and critically endangered species of porpoise found in the northern Gulf of California.
Why are vaquitas endangered?
Vaquitas are endangered primarily due to entanglement in illegal gillnets used for fishing in their habitat. The use of these gillnets, particularly for catching another endangered species, the totoaba fish, leads to accidental capture and drowning of vaquitas. The demand for totoaba swim bladders, considered a delicacy in traditional Chinese medicine, has driven this illegal fishing activity. The vaquita population has sharply declined as a result, making them critically endangered. Efforts are underway to address this threat and protect the remaining vaquitas.
Why are vaquitas being poached?
Vaquitas are not poached themselves; they fall victim to illegal gillnet fishing practices targeting another endangered species, the totoaba fish. The swim bladders of totoaba are highly valued in traditional Chinese medicine, leading to illegal fishing in the Gulf of California where vaquitas inhabit. Unfortunately, vaquitas get entangled in these gillnets, and as a result, they face accidental capture and drowning. The illegal trade of totoaba swim bladders drives the demand for these gillnets, posing a severe threat to the already critically endangered vaquita population. Conservation efforts aim to combat these illegal practices and protect the remaining vaquitas.
How many vaquitas are left in the world as of 2023? (What is the exact vaquitas Population?)
The initial extensive survey of vaquitas across their range in 1997 reported a population of 567 individuals. However, alarming declines ensued, with estimates plunging to 150 by 2007 and a further decrease to less than 19 in 2018. The devastating impact of bycatch and the challenges of low reproductive output from a dwindling population have led to a current estimate of fewer than 10 vaquitas as of February 2022. The precarious situation persists in 2023, with ongoing estimates suggesting as few as 10 individuals remaining in the wild.
What is the lifespan of vaquitas?
The lifespan of vaquitas is estimated to be around 20 years. However, due to their critically endangered status and the ongoing threats they face, many vaquitas may not reach their natural lifespan. The primary cause of concern for vaquitas is accidental entanglement in illegal fishing gear, particularly gillnets set for another endangered species, the totoaba fish. This threat has led to a rapid decline in the vaquita population, making conservation efforts crucial for their survival.
Which species of the vaquitas is the smallest?
Vaquitas (Phocoena sinus) are a species of porpoise, and they are relatively small marine mammals. Among porpoises, vaquitas are considered the smallest species. They have a compact and slender body, typically reaching lengths of around 1.2 to 1.5 meters (4 to 5 feet) and weighing approximately 40 to 55 kilograms (88 to 121 pounds). Their small size is one of the factors that make them particularly vulnerable to threats such as accidental entanglement in fishing gear, contributing to their critically endangered status.
