Regarding the eating habit of sailors, a Japanese sailor rescued by a whaling ship of the US in the 19th century recorded that American sailors on the ship did not eat the meat of large-sized whales because they considered the meat is bad for them, but ate dolphin meat on rare occasions.
同じく19世紀にアメリカの捕鯨船に救助された日本人船員も、アメリカ人船員は大型鯨肉は毒だからと食べないが、イルカはまれに食べていると記録している。
