Follow @EcoJive : An orca named Granny was recently spotted swimming off the coast of Vancouver Island with her family. Seeing a wild orca is always an unforgettable experience, but getting a chance to see Granny is a gift: This old lady of the sea is believed to be 103 years old! Grannys pod, referred to by scientists as the J2, is the most widely studied group of wild orcas in the world. Researchers began tracking the J2 family in 1970 and believe the familys matriarch was born around 1911 -- just a few years after the Wright brothers took their first flight. Just imagine the stories Granny must tell to those around her. Swimming up to 100 miles every day, wild orcas days are filled with adventures and challenges, interactions and complexities. Orcas share news, work together to solve problems and have a rich cultural history. The scope and scale of what Granny has experienced and passed down to other generations over the past century is mind-boggling. Compare and contrast her life history with that of her cohorts in SeaWorlds tanks. Most never make it to anywhere near their life expectancy. At least 37 orcas have died, from captivity-related causes ranging from severe trauma, intestinal gangrene, acute hemorrhagic pneumonia, pulmonary abscesses, chronic kidney disease, chronic cardiovascular failure, septicemia and influenza. Their experiences are gut-wrenching and show SeaWorld to be the biggest, worst orca prison on Earth. As we celebrate the long life of Granny, lets remember what life is like for those who were kidnapped from their homes and families and those unlucky enough to be born in SeaWorlds tiny tanks. Ripped to Pieces Nakai, an 11-year-old male orca at SeaWorld San Diego, sustained an injury on his lower jaw that was so significant that it was described as a dinner plate-sized chunk of ripped-off tissue. Its believed that Nakai was injured on a sharp metal edge in his tank while reportedly fleeing from an aggressive altercation with two other orcas. The chunk of flesh was big enough that SeaWorld staffers were able to retrieve it from the bottom of the tank.

SeaWorld personnel drill out broken or worn-down teeth to prevent abscesses and infection. The resulting bore holes require trainers to irrigate the teeth multiple times each day. Credit: David R. Tribble | cc by SA 3.0 Dead in the Water An orca named Taima died while giving birth to a stillborn calf at SeaWorld Orlando. The baby was the offspring of Tilikum, the angry and frustrated killer whale who battered trainer Dawn Brancheau to death. Taimas mother, Gudrun, had been snatched from the ocean in the 1970s; she gave birth to Taima in 1989. Another of Gudruns calves was born with mental and physical disabilities and lived for just a short while. And she also had a stillborn calf who had to be extracted from her body using chains. Gudrun died four days afterward and never got to feel the ocean currents or hear the voices of her family members again.

SeaWorld breeds female orcas who are still just youngsters themselves and has even bred a mother with her own son, resulting in numerous unsuccessful births. Even though orca families stay together for life, SeaWorld tears calves away from their frantic mothers so that they can be shipped to other parks and forced to perform.

Orcas are meant to swim far and wide every single day. Marine scientists believe that lack of exercise and confinement cause orcas connective tissue to weaken and collapse.
