Beluga whales are smaller-sized whales that are very social and inhabit Arctic and sub-Arctic waters. They are rarely reported outside of this range. However, in October 2021, a lone beluga appeared in the waters of the Pacific Northwest (PNW) and remained in the area for approximately a month. This presentation will describe the biology and ecology of whales; the case of the lone PNW whale; and current threats and challenges that face wild populations of beluga.
