A juvenile humpback whale was spotted in Unalaska Bay on Sunday night. Alaska Sea Grant biologist Melissa Good took tissue samples, but was unable to perform a full necropsy.
Two dead whales have washed up on Unalaska's shores in the past week: an adult fin whale — which is the second largest mammal in the world — and a juvenile humpback.
And while local biologists hoped to determine the cause of deaths of both whales, because of COVID-19, they likely won't be able to.
That's because it takes a large team of individuals to do a whale necropsy — or animal autopsy — which, in order to protect public health and adhere to social distancing requirements in the wake of the pandemic, just isn't possible, according to Melissa Good, the local marine advisory agent with Alaska Sea Grant.
"Human safety is always the number one priority," Good said. "Other places have difficulties with doing necropsies, whether the animal floats into a remote area or there's bears in the area — you're always putting human safety first and then going, 'okay, can we get a sample after that?' Right now, it happens to be that COVID-19 is at the forefront of all of our minds. And it's something that we all need to be cognizant about, and continue to protect ourselves and the community. So we just can't take those risks."
Unalaska typically sees about one dead whale wash up on its shores every year, according to Good. And when that happens, a team of biologists often perform a necropsy to determine the cause of its death.
