Ocean First Institute presents "The Shocking Lives of Electric Rays" - a webinar with Dr. Laura Ekstrom

Most of us have heard that sharks and rays can sense electricity, but did you know that some of them can make it, too?! The electric rays are a group of ~70 species that all possess large electric organs in their pectoral fins. These electric organs can be used in defense against predators or for use in capturing and killing their prey. A shock from one of the larger Torpedo rays can even be fatal for unaware divers. During this presentation, Dr. Laura Ekstrom (an OFI Advisory Board Member) will share all about how they make their electricity, how they use it, and where you can find these truly amazing animals!

Laura’s research experience includes elasmobranch (shark, skate, and ray) behaviour, physiology, and biomechanics. She has extensive experience in elasmobranch husbandry. Current work includes investigations into the mineralization of the elasmobranch skeleton, patterns of locomotion in benthic rays, and the biomechanics of body stabilization.

Dr. Ekstrom completed a Postdoctoral Fellowship at Mount Holyoke College and is currently an assistant professor at Wheaton College in Norton, Massachusetts. She is an active supporter of women in STEM and is a co-founder of Wheaton’s Summit for Women in STEM, a one-day conference to highlight, mentor, and connect women in STEM across New England.
