Also known as J2, some researchers believe that Granny was born around 1911 while some with more conservative methods claim it was closer to 1960. J2 had a very specific characteristic: a grey spot on the back of her dorsal fin and a half-moon shaped notch. In 1967 she was captured together with a group of killer whales but hunters thought she was too old to be kept in a zoo or aquatic park. If it’s true that she lived 105 years, that would make her the longest-living killer whale.
