Dolphins, One Species at a Time, by Ari Daniel

You have probably seen cans of tuna in your local supermarket marked “dolphin safe.” That label means the tuna was fished in a way that spares most dolphins from being killed in the tuna fleet’s giant nets. Biologist and guest reporter Matt Leslie brings us a story about tuna, the intertwined fate of fisheries and dolphins, and the work of scientists. It’s a story that lies behind the label of every can of tuna. It spans two generations of scientists and a revolution in scientific methods. Matt reports from a dolphin morgue in La Jolla, California, USA.
