Abstract

There are many species of cetaceans in the waters around Japan. Some are migratory, but others seem to be permanent residents. The rarities among the small cetaceans caught by Japanese fishermen in recent years are Stenella attenuata, Feresa attenuata, and a black individual of Phocoenoides. I am planning to present a detailed account of them in the Scientific Reports of the Whales Research Institute, but I will introduce them here briefly.
