The octopus population in the waters south of England is booming. Typically a rare species, fishermen in one town pulled in more than 70,500 pounds of octopus on a single day — compared to the usual average of about 400 pounds. This population boom comes as those same waters are experiencing a marine heat wave that has lasted for several months. Host Carolyn Beeler speaks with marine ecologist Lissa Batey about the increased population, the response from the fisheries and how the overall marine environment is shifting due to climate change.
