Killer whales (Orcinus orca) and humans. In 1977 a pod of about thirty killer whales were seen attacking a 18 m (60 ft) blue whale off the tip of Baja California. European whalers first targeted the blue whale in the 1860s. Peak catches were reached in the early 1930s, when nearly 30,000 were caught in a single year.

Young Killer Whales are theoretically hunted by large sharks, although this is considered unlikely and has never been witnessed. As adults, it is theorized that Great White Sharks may try to "sneak-attack" stray adult specimens. This, again, is theoretical, as it has never been witnessed, and Killer Whale almost never 'stray' from their family pods. Killer Whales are also far larger then even a very large Great White's normal prey size.Additionally, Killer Whales are hunted by Man in Japan, Argentina, and Norway, though this is sporadic.The killer whale's enemy is man. If it isn't our pollution that kills them, it is whaling.Another sad fact is that whales kept in theme parks, sometimes live in squalid conditions for our entertainment. All for mans selfish need to make money.
