How Do Deep-Sea Fish Get It On?

Do you ever watch Finding Nemo and wonder about the scary-looking fish with the gnarly teeth and the light on its head? Well then you’ve come to the right place! This week, we’re talking anglerfish! Marine biologist Dr. Mackenzie Gerringer and Jonathan spill the tea on what’s going on in the deep sea. We cover everything from how big the Mariana Trench is to how the deepest-living fishes reproduce–and it's WAY weirder than you think!

Mackenzie Gerringer (she/her/hers) is an Assistant Professor at the State University of New York at Geneseo. Her research centers on the physiology and ecology of deep-sea animals, including the planet’s deepest-living fishes. She earned her PhD in Marine Biology from the University of Hawaii in 2017 before working as a postdoctoral researcher at Friday Harbor Labs, University of Washington. She has spent over 200 days at sea exploring the ocean’s depths with free-vehicle landers, ROVs, and submersibles.

You can find more information about Mackenzie and the projects her lab is working on, here, and you can learn more about human impacts on deep-sea ecosystems, here.
