North Pacific right whale #87 also known as “Smudgy” interacts with a log floating on the water. There are only around 30 individuals in the eastern population, so to spot a North Pacific right whale is rare and to see one interacting with a log in a once-in-a-lifetime experience. NOAA Fisheries permit 782-1719.
