The Vaquita's wikipedia page is also saying there are only 12 of these porpoises left.
The WWF page doesn't appear to be quite so up-to-date in its statistics, as it is still saying there are 30 left.
Not that that number is much better, in the grand scheme of things.
In fact, it's pretty horrifying.
Attempts by the Mexican government, alongside conservation groups, in November of 2017 to capture some in the hopes of beginning a breeding programme failed as one of the females died shortly after collection. Quite a setback to a plan with good intentions.

They are not hunted in their own right, but caught up in the gilltrap nets used to collect the Totoaba - an endangered fish harvested for its swim bladder (a Chinese delicacy in soup, and medicine).

They are an important link in the biodiversity chain which exists within their habitat. Their loss will most certainly have a ripple effect; and indeed with such low numbers their whole genetic diversity is affected, as is their ability to even breed.
Please, spread the word before it is too late.
