Activity content: Humpback whales of the Ogasawara Islands
The Ogasawara Islands are one of the breeding grounds in the North Pacific, consisting of three groups.
As it is said, "Whales are creatures at the top of the food chain," their ecological status and role as higher animals in the marine ecosystem are significant. The lower organisms that serve as food for whales show considerable annual variability, and the composition of whale diets responds sensitively to these changes. Additionally, due to the characteristic of higher animals to accumulate pollutants, whales are particularly susceptible to the effects of heavy metals such as mercury and cadmium. Studying whales not only helps to elucidate their ecology but also provides clues to understanding changes in marine ecosystems and the realities of marine pollution associated with climate change.
