Check out this awesome issue of the American Cetacean Society’s magazine, called the Whalewatcher. The issue is called “Porpoises on Peril: the Vaquita and its Relatives,” which, as you might guess, specializes on the porpoises. You can read it here: Whalewatcher.
A very well-written article completely about the Vaquita can be found in the new issue of Audubon Magazine! It is called “Safety Net”. Please purchase the magazine at a local bookstore, or check it out at http://www.audubonmagazine.org/articles/conservation/safety-net-0. This article is extremely vital to the Vaquita.
