More about Meduse

The right side of Meduse's mouth is covered with wounds not seen on the left side. This is interesting because studies have shown that most rorquals (the largest group of baleen whales) exhibit a strong right-side rolling preference while filter-feeding. Based on the newly acquired knowledge of their bottom feeding behaviour (see post on Exciting results from Operation Calanus), it appears that the humpbacks in Mingan also display this peculiar preference when they find food.
