A team of scientists from Woods Hole Oceanographic Institution (WHOI) and NOAA Fisheries are collaborating to help stem the decline of a critically endangered population of beluga whales in the Cook Inlet, Alaska. A study recently published in Animal Microbiome outlines important first steps in understanding epidermal microbial communities in beluga whales, as well as their role in beluga health. This study is one piece of a larger puzzle for researchers looking at everything from social structure to acoustic interference and contaminants, all with the shared mission to reverse the dire decline of this vulnerable population.
