Amy Klink, a graduate student working in the laboratory of Dr. Allyson Hindle at the University of Nevada, Las Vegas, has been studying hypoxia tolerance of Weddell seals. These remarkable animals can hold their breath for 90 minutes and dive as deep as 900 meters! During such long and deep dives, these seals slow down their heart rate and constrict blood vessels in visceral as well as peripheral organs. As […]
Dr. Allyson Hindle from Massachusetts General Hospital in Boston, presented some interesting research on seals at the Experimental Biology conference this week in San Diego. Seals are known for being rather plump, which for humans often leads to inflammation and cardiovascular disease. In addition, seals undergo repeated bouts of hypoxia and reoxygenation during their dives, which is also known to promote inflammation and cardiovascular disease in humans. Her research team […]
