With all the hype around shark tagging, sometimes I joke, "What did scientists do before tagging?" I'm pleased to begin sharing interview segments from my visit with a shark researcher, @alessandrodemaddalena70 , who is opposed to invasive methods. Who would like to see the rest of the interiew? And by the way, happy birthday Alessandro! #observationscience #sharktagging #savingwhat? #whitesharks #sharkscience Interview filmed by @mjbillen
