Out of 497 photographed sightings, 445 were determined to be usable in the analysis, and of these sightings, 47 displayed Xenobalanus: 38 odontocete sightings and 9 mysticete
The new findings suggest that Odontocetes and Mysticetes

Though large sperm whales often yielded more than 40 barrels of oil, mysticetes
