I'm David Shiffman (@WhySharksMatter) , a shark scientist at the University of Miami. Happy Shark Week! AMA!
Hi, reddit! I am a Ph.D. student at the University of Miami's Abess Center for Ecosystem Science and Policy, where I study shark ecology and conservation. I went to Duke for undergrad and have a Masters in Marine Biology from the College of Charleston.
I've interacted with over 3,000 sharks on 3 continents. Our lab, the RJ Dunlap Marine Conservation Program, took over 1,000 high school students into the field with us last year to help with our shark research, so let me know if you're a high school teacher (RJD.Miami.Edu/Participate)!
I write for Southern Fried Science (southernfriedscience.com), one of the most widely read ocean science blogs on the internet. I also tweet about sharks @WhySharksMatter , and am always happy to answer any questions that anyone has about sharks.
Happy Shark Week! Ask me anything. UPDATE: After 600 questions and 3 hours, I'm exhausted. You can find me on twitter @WhySharksMatter and I'll answer your questions later. Thanks for having me, reddit!
