Granny (orca)

Granny, also known as J2, is an orca, or killer whale, estimated by some whale researchers to be 104 years old, which, if correct, would make her the oldest known living orca. Granny had been captured with the rest of her pod in 1967 but was too old at that time for a marine mammal park, so was released. In 1967, Granny was estimated to have been born in 1911. (The lifespans of wild females average 50 years, with a maximum of 90 years. Wild males live around 29 years on average, with a maximum of about 60 years.)
==Description==

Granny is recognizable from the gray "saddle patch" just behind her dorsal fin, and a half-moon notch in her fin. Simon Pidcock of Ocean EcoVentures said he has seen Granny thousands of times, and that the markings on orca fins are like fingerprints.〔
Now that orca studies have been going on for several decades, the exact age of many whales is known. The age of older orcas, such as Granny, is estimated by their offspring; they give birth around age 15, and stop having offspring around 40; by adding the generations together, ages can be estimated. There are also photographs of Granny from the 1930s and the size and growth of Granny and the other orcas is also used in the age estimates.〔 In Granny's case, she was photographed in 1971 with a male orca, J1 Ruffles, who was thought to be Granny's son. Ruffles was estimated as at least 20 years old, and as scientists believed him to be Granny's last offspring, her own age was estimated at about 60.〔
