The Vaquita is a small porpoise that is severely endangered. Up until now there has been a no take zone in the upper gulf of California, in order to avoid accidental bycatch, but unfortunately that has been eradicated.
With fewer than a dozen Vaquita left, this is likely to be the end, as bycatch of even just a couple a year will mean the little porpoise is no more very soon
Time will tell if conservationists are correct
