The vaquita is the world's rarest marine mammal. How few of these porpoises remain?

The correct answer is: As few as 30.

A survey conducted last summer and released in early 2017 estimates that the number of vaquitas is at an all-time low. The reason for the sharp decline is bycatch—fishing nets that inadvertently catch and drown the porpoise.

Vaquitas share waters with the much sought-after totoaba fish. The totoaba’s bladder is a highly prized delicacy in Asia and is illegally traded en route to China from Mexico and through the US.

The only way to save the vaquita from extinction is if the Mexican government bans all fisheries within vaquita habitat. WWF is committed to working with the Mexican government and the international community to ensure a future of the vaquita as well as sustainable livelihoods for local communities. Find out more.
